"Adding power might make you faster on the straights but subtracting weight makes you faster everywhere." Ahh, Colin Chapman's Lotus philosophy! Great video Hoki :)

I always end up in A class with a 2000 pound car that has 320hp and can only go 140, but god do they turn lmao

0:16 Conversions 2:11 Aero 3:14 Tires and rims 5:54 Drivetrain 7:14 Handling 9:30 Engine 12:00 Overall Priorities Found myself coming back often, so I put down the chapters

This could be used as a quick reminder. I did not read any comments and also wrote this down in one watching of the vid., so take this with a grain of salt. Summary 12:00 Prioritize: Antiroll Differential Wheel spacers Race/Rally/Drift Tires and braking Shift quick enough Gear rations Weigh reduction Power Long version: 0:00 - 12:00 Conversions: Engine swapp: Stock engine unless pushing into other class, as they have better PI value. Drivetrain: Recommended to leave as is. Execptions online for launch speed Turbo: Generally preffered over superchargers. Good choice if you cannot reach power goals with NA engine. Superchargers: More weight and less peak power, linear power gain and starts lower in the rev range. Aero: Forza parts very useful on high class cars. Generally worth on A+ class cars. Add(for appropriate front/rear) only if you are struggling for front/rear grip. Wheel & Tire mods: Compound: Choosing right compound should be chosen by temp. Drive around and inspect tire telemetry. Blue too cold - downgrade Transperant good Yellow too hot - upgrade Width: Max for driven wheels Rims: Can reduce weight 17"+ recommended Bigger wheels = more weight, more responsive handling, better grip Go for spacers if possible Transmission mods: Clutch: Huge help on manual cluthless and automatic Not worth if you are driving on manual Transmission: Upgrade if stock gear ratios are off or need faster shift time Driveshaft: Go for it, weight reduction Differential: Does not cost any PI, go for it Breaking: Max is not always better. Max braking for A+ Only upgrade if you are not maxing out braking Open up telemetry and check the peak braking power: Under 100% - downgrade Over 100% - good, might benefit from upgrade? Suspentions: Skips street/sport Race Drift Rally according to the mode Antiroll: Max Chassi reinforcement: Most do not need any Extremely useful for older cars that are pushed into a higher class Raw weight reduction: Great if you can affford PI. Choice between POWER/WEIGHT R. = Shave weight instead of adding power. Prioritize losing weight in wheel / driveshaft / flywheel weight over raw weight reduction Power: Intake - lower priority. Increases power/torque sometimes reduced weight Throttle body - lot of power and torque and shave weight. Good way to add power Fuel system - good mod power and torque does not shave weight Exaust - higher priority shaves a lot of weight, adds good power and a lot of torque Cam shaft - highest priority lots of power/torgue and increased redline Valves - lower priority Displacement - a lot of extra power/torque Compression - lower priority Turbo - higher priority great way of adding a ton of power Cooling(intercooler/oilcooling ) - avoid if you can get power else where. On simulation helps to prevent engines from overheating, otherwise justs adds weight Flywheel - good way to add/reduce few PI

That's my philosophy too: prioritise handling. A slow car that can turn at full throttle is faster than a fast car that needs to brake at every single turn. I often win races against more powerful cars because my car can do almost all the race at 100% gas

Hoki, has anyone told you that you have such a calming and beautiful voice. Love this video by the way.

"Adding power makes you faster on the straights, but subtracting weight makes you faster everywhere." One of my favorite quotes :)

Die hard sim players: “now you don’t want to max out everything and you want to prioritise speed or handling” Ever other FORZA player: “so guys just maxed out my new car to X999 class can’t wait to go so fast”

After binge-watching all of your videos since I recently discovered your channel, this was the last guide that I desperately needed! Your content has made me a millions times more interested in this game and it's community, so thank you for making really enjoyable and accessible guides for us!

As far as upgrading process (in terms of what to upgrade first) I pretty much always have the same structure, prioritized after usefulness (filling the PI with the big rocks (important upgrades) and filling it with the sand (nice-to-have stuff) afterwards is much easier than filling in the sand and _then_ trying to get the big rocks in, if you want to go with that image). Interesting to note though: the PI is actually calculated in-game as a floating number (IIRC) - that's why some upgrades don't change PI at first, then suddenly do after you come back to it from upgrading the rest, that's why it's a good idea to leave some tweaking points. *1) Conversions (duh).* Changing this after you upgraded the rest defeats the purpose as you replace your upgrades. *2) Tires.* I usually have a PI goal in mind, and I prioritize this over anything else because my car will literally stand or fall with this. Tire compound first, then tire width, then track width. I leave the rims as a tweaking point for later (since Forza doesn't differentiate between sprung and unsprung weight, it's just more weight shaved off). *3) Aero.* As a rule of thumb, I try to leave the aero stock below S1 class. In A class if a car is particularly unruly, but mostly I get by without; I found it costs quite a bit of PI and the handling hit I take for not taking Aero upgrades is negligable for the most part in A class and below. *4) Transmission.* Unless the gears are completely wonky, final gear tuning is enough. Clutch I only upgrade if I feel the shifting is too slow. Differential costs no PI and adds tuning options, so always take that. Driveline I leave as a tweaking point, since sometimes you can get away with upgrading your driveline without upping your PI and the performance boost isn't high enough to prioritize this over more power IMHO. *5) Platform and handling.* Suspension > ARBs > Brakes > Weight Reduction (depending on the car); Roll Cage only in cars that aren't -race cars OR - built after 1995(ish). Or in some cases, just as a way to optimize the front weight percentage. A good indication when it's a good idea is when it adds more than 2 PI. *6) Engine.* Camshafts > Exhaust > Fuel system > Fly Wheel > anything else that brings me up to the PI I want. BONUS: *7) Transmission.* Going back to check if I can sneak in a driveline upgrade :D

Me: slaps all max upgrades on my car and makes them all s2+

Dude, this was so incredibly helpful - thank you. I was finally able to tune/upgrade the 22b which was impossible to use before with my crap upgrading.

Thank you for making these. Just came here via your tuning guide - these are really helpful videos, very clear and calm, and very much appreciated.

Drift suspension is usually 1lb less than race, sometimes 0, but can be tuned back to race alignment & stiffness. This provides no advantage over race suspension in a race but in freeroam rush it is hugely beneficial to have extra angle to bring yourself out of bad situations.

I’ve found a very enjoyable niche in B class... not too fast but fast enough to still feel like a race and not a parade.

You have no idea how much you've helped me Hoki. Thank you so much 🙏

I was desperatley looking for such a video by release of FH4....thankx for doing now!

These videos are really helpful because I don’t know much about upgrading and tuning cars Thanks a lot

Great video as always bud. Saw somebody else mention this below, a video on the different engine swaps might be good. What cars they come from, what type of racing they are suited to and whatever else is relevant lol. Anyhoo keep up the good work! ✌️

The tuto I wanted so bad!!! Thaaaank you!

Excellent video! Man I want to drive one of those irl

Good clear info. Thank you

Thanks man!! You've earned my respect

Great video mate the only thing that I would argue is the tire telemetry part I would keep the Grippy tyres but raise or lower the tyre pressure accordingly

These videos are great ! Thank you

One thing to keep in mind is that the camshaft upgrade essentially extends your gears without having to purchase the transmission with adjustable final drive. In some cases you can use this to your advantage and not have to buy the trans to get the speed you need.

It might be important to note the camshaft upgrade also changes the torque curve, especially noticeable on the rally engine swaps since they're tuned for specific RPM and have airflow restrictions, it's still usually a good idea to take it, but if you want to keep the mountain of torque low down you have to keep them stock.

Exactly what I was looking for, thanks

Insane video, keep up

Not gunna lie its about time someone did a guide on upgrading and not just streaming they're gameplay. Just a suggestion your next video SHOULD be fine tuning. ;)

Thanks Hoki your a real life saver

Very helpful and too the point. Subscribed

Side note : Rally suspension is good for drag dracing as it improved 0-60 time and you can add height in the back of your car

Finally. There hasn't been one of these since DJS did one for horizon 2

Hey Hoki! Your videos have helped me so much, and I really enjoy watching them! Keep it up!!! 🔥🔥🔥

Woah. I didnt know about the tire compound temperature and brakes hitting peak grip, thanks man!

Thanks for the info dude

Awesome video as always :D So helpfull

About Radiator and Oil Cooling, you can balance it by prioritizing Air Intake, Exhaust, Valve, and Piston with race option and add Radiator/Oil Cooling on sports/street option because they only add a little weight. I've been experiment with radiator/oil cooling and sometimes it can balance engine response and make other upgrades more effective for adding power.

This helps so much I enjoy A and S1 the most.

I love this tutorial but I will still keep my Isetta which was tuned to spin like beyblade when you floor the gas.

very helpful :)

Very good. Forst time I've watched your vids. Obviously you're a Forza expert. Very informative for the beginner to the seasoned vet. (Taught me something!) I'd like to point out, most of this applies to both motorsport as well as horizon. Rally parts being the main exception. I will be referring my Academy members to your channel. Thanks for the high quality, in depth info!

One caveat to weight reduction is that it'll make tunable suspension more necessary (as does the change in weight balance that usually comes with engine swaps). In certain cars where you only want to bring them up by less than a full class, more power and/or stickier tires can be the full upgrade (and sometimes the extra weight from differet/bigger/wider wheels/tures or chassis stiffening) can help keep them in a lower class than they would pop into with the added power might put them just a few points over.

Driving with a wheel means I prioritize handling (tires/anti-roll/suspension/gearing etc...) and weight, then add power if there is any room left as a last concern. If I am tuning specifically for an event I prioritize tires and suspension then tune gearing for what I anticipate will be my top speed in the event (playground games doesn't require a high top speed so I can have a close-ratio tune that will make me faster than everybody else and keep from bogging).

Great video... slightly disagree with tyre. What i have found is if your car is slipping while cornering, upgrading tyre fixes it. You can corner fast. Temp is not the only deciding factor for tyre.

I'm a new player, thanks for this video

I've been doing it wrong this whole time. Extremely helpful video!

Great video ,only 1 aspect missing,in all the forza games ive played from forza 2 till now,the weight distibution front to back is made very important . Even drifting cars,front to back dist of 50 % is what I always give priority after weight and tyre. Because the weight distribution has a overal bigger effect on handeling in general. Plus the upgrades that effects this are the ones that most of the times can even downgrade the pi. One of the more advance tuning ways is upgrading for even weight distribution. I know for sure that You know what I mean,i could explain coolers en oiling upgrades with a certain engine and charger can make a almost drifting race car transform into a car as relax handeling and save as a volvo ( just an example ,a volvo is ..well pff In the end the cars that have that great handeling al ready stock always have that ratio of 50 . For a drag rce it doesnt matter and using an engine designed for drag or streetrace when rally or city racing is not the way. But if for example a high performance car is what u using in moderate to high rev range and power band track( like most of the tarmac race in fh4 then going for the weight distribution is the logic thing the v12 engine with awd swap and max turbo plus cooling and oil can make a 45 % to the back sliding nightmare suddenly into a 50 % relax car. Mostly it is the best way of gettimg a front bias car ,like many of the muscle car ,lose that terrible understeer. Im sure that many of you know the frustrating feeling of a high powered ford that goes like a rocket but almost needs to park on every low speed corner,and can be used as a landscaper on those long sweeping speed corners. That Problem Can be solved the way I said. Because almost every other way one loses a lot of the power and acc. This way one can have the raw power of a great muscle car with the cornerimg of a rdical. The radical is the most over looked handeling car in the game ,not that senna or mosler or f1 is the best handeling car ,but the radical is ,it has the cornering feel of a lmpt car in forza motersport ,if it would lack that little bit of max speed it would be the far best car. Hey dont believ me ,just pick goliath and leave it stock ,you wil,not beat the f1 or the maserati because those a faster,but you will have an easer ride for sure...try a hill climb or down on fortune island..

Great video

Thanks Rob! Your explanation is very helpful as always! :)

1 thing to add, superchargers are usually used irl since its technically easier to just slap on a supercharger. But in game, u should just upgrade the main engine since it doesnt add weight

Amazing man! Thank you very much for share these informations. I started driving in the class C to learn how to drive correctly because of your video about drive education. Now, I will try to improve the setup of my car in the class C based on this video. Thanks. 👍

This is exactly what I’ve been looking for. Thanks my brother 💪🏽🔥🔥

D class, B class and and A class are the most fun with proper tunes

holy hell I learned a lto from this video. Now time to re tune all of my cars lol

wow. I never thought it would be this advanced... "if you cant heat up your tyres to proper trace temps..." i liiiike it! will put my new wheel to good use in forza it would seem Hope driving in GB wont messing me up too bad :P

You have the most useful videos on FH4 !

Just to mansion. In real world you prioritize tire temp whatever tire you've got by adjusting tire pressure so can get you to somewhere in max window grip. not the other way around. Great stuff! "Always sacrifice feeling over grip" Petter Solberg

This is the 5th video of yours that I’ve watched, planning to improve my Forza skills a lot in the near future 😏

Tuning is much more important than modifications. After putting in all parts that unlock tuning options (ie sway bar, diff), it just comes down to personal preference on mods.

Most of the cars I have are either s1 or A class I tend to find those cars the most fun to drive

I have tuned a AM Vantage GT12 with AWD and its Beautiful in S1 Street scene / Road racing, and still doesn't try to kill me in Winter.

They need to add a AWD category and FW/RW category. You’re at a huge disadvantage throughout the race

this is the first forza games i've ever played and i need some edu about cars because forza isnt about whos the fastest

Hi. The brakes also reduce the weight significantly. Moreover, they also affect the initial phase of the turn

Very helpful! Thanks very much for explaining!

I have a tuned 2002 Turbo that I drive all the time. It is 11,000+ miles on it. I designed it to look like my 1982 320is as much as possible. Anyway; I have tuned it with the drift suspension and it handles pretty well. If I don’t let off soon enough around a corner; I will spin out. I have a second 2002 turbo that has the same tune but on race springs. After doing 50 laps of the Falcon Speedway Loop, the drift suspension did put down a fast time but was trickier to learn on track. My advise is, if you want a challenge and you know how to handle a bit of snap oversteer, absolutely use the drift suspension for course racing. Also that extra steering Angel can be fun to mess around with on the streets.

Well the main thing i learned today is that your car can overheat on sim damage... and also never knew the exhaust upgrade made your car louder?

YOU ROCKS HokiHoshi. You are the best Forza KZfaqr :3

The LSD goes straight to 75/75. When it's stock it'll have different numbers on the slider for different cars.

Your tuning quickies have helped me fix my fwd and rwd cars. But can we get an awd guide..

awesome guides. i m just starting out with tuning and well most if it is probly pretty bad but i dont even care. i dont expect to create the best tunings in the world but as long as they work, im fine with it. i think its a pretty solid trade off for flexibility. because downloading other tunes allways made me feel.. helpless. for example winter season. you wanna edit your tune and slap on winter tires... well you cant do that because its locked and you need to pray for mercy that someone creates a winter tune... i just wanna do stuff myself for whatever car i wanna drive (and those cars are usually off meta cars since i wanna be that weird guy who s using that car noone uses simply because it looks good) lxD

I just thought I'd mention, you can tune your car and adjust the PSI of your rear and front tyres (tyre pressure). This can affect the heat of your tyres. A good rule of thumb is to adjust your tyre pressure so the tyres are just before yellow on the Telementary HUD when driving, this is usually around 170°F. You should note that tyre pressure is not as much of a serious factor in rally racing than it is in road racing. I recommend you balance out the tyre pressure for the front and rear tyres for rally racing and purchase the widest tyre profiles you can buy, this will keep the car somewhat planted in the dirt and allow you to make rather quick corrections.

Ive always prioritize handeling uprgrades then power

I made an abomination of a awd corvette, still have to adjust some gears till its fully ready lol

I still use street and sport suspension if I’m too lazy to adjust spring rate and damping but when using street and sport they are stiffer by a lot compared to stock. Note: if you decide to run street or sport suspension always put race sway bars on and upgrade your tires at least one compound unless your vehicles already on race tires or race slicks. If you don’t upgrade tire compound it’ll feel like you’re driving on ice. And if you don’t upgrade sway bars your car will always lose traction. Also make your sway bars softer seeing how street and sport suspension is stiffer

thank you! thanks to your videos, I am starting to understand tuning and cars, so I don´t have to call my brother to tune my new cars... saves time and I am starting to have fun with it.

So much you'll have to know^^

Hoki hoshi I am so glad that you actually answered my question, to be honest I never was expecting a video in response of my comments because I always feel like my comments go unseen which I can understand you can only read so many comments at a time but anyway I appreciate you answering my questions, thank you for your help!

AWD swap is a must have if you play on keyboard, if you put RWD on a car and increase horse power, you end up just spinning tires, also cornering isn´t much fun.

As usual your video reveals, thanks. Like the Colin Chapman quote.

There’s also some cars that have awkward setups for their upgrades when trying to stay in the pi range. Sometimes the camshaft upgrade isn’t worth it in manual with/without clutch because you can match the max upgrade if you can well past the redline and there’s the potential non peak torque loss. Idk if this has any negative consequences in simulation mode by damaging/overheating the engine though.

I really only find aero good on S2 cars. S1 and below I just generally stick to the stock design and put the PI into other areas. I've found this game really likes cars with a focus in power.

The Nissan GTR LM R33 Forza Edition's premade setup comes with AWD and handles much better than if you were to do an AWD swap on a normal GTR LM R33

I've noticed that power to weight ratio always seems to lean to adding power before raw weight reduction. I didn't do a ton of testing before coming to that conclusion but it seemed fairly consistent through about 20 cars that I tested it on.

Forza doesn't differentiate between sprung and unsprung weight. The only difference maker where weight is concerned (AFAIK) is weight balance (aka "front weight percentage"), driveline, and the fly wheel.

My Z06 uses awd and is great with fine tuning

This is the best video. It’s missing the track width parts because of the sample car. Can you explain if I using a FR BMW 2002, should I max the rear width and keep the front width as original ?

Been playing FH4 for a couple months and I did not understand one single bit about this video. Guess i'll just choose a few cars and max them out.

No one: Younger me: max out everything and wonder why it drifts by just looking at it

Hey man, love your videos. :D Could you maybe do a tutorial for clutch techniques for drifting? I'm looking to improve my technique & records a bit, and find your videos really helpful :) Btw my best record is 172.532 on my fav drifty-zone (Kirk Lock, located next to Arthur's seat, Gamertag Lenny52), but i'm kinda stuck now... And thanks for reading! :)

Uggggh I've been waiting for this! Cause the Forza Tune app helps you tune but no help with mods. Although maybe a video about just engines would be nice?? I know you said it's preference but I don't know the difference lol

"If you can reach your power goals with the naturally aspirated engine, that's generally better" but turbo sound good :(

Would love to see an update for fh5!!

Some times too much power will make a lot of wheelspin on the tires it will make them a drift

I always find cam shafts add way too much pi, I max upgrade the brakes as I like to tune the braking balance so the rear tyres are being fully utilised in a braking zone, it does mean if you lock up you are very likely to spinout, but you do stop faster

The v12 maxed out naturally aspirated is balanced too. 797hp

Aim for 350-500HP for A class, 550-800+ for S1 class. Rally tires can be great on both A and S1(4WD) class cars if you are too lazy to make another car for winter/rally racing. Try out different engines. In some cases you can get the same PI with a lower rev engine, more usable power, and 10% boost to the power, which will get you around 5% higher top speed (ex:NSX-R GT is better with the V6 engine rather than the v-tec one) Other cars will benefit from high revving engines, in my experience, the lower the power.

Never underestimate a grippy car I beat plenty in circuits with them
