Things are progressing slowly with the car, so thought I´ll respond to another common question regarding the open differential. Yes, it has a completely open diff. I would like to say that a LSD isn´t needed if a car is setup properly but for the sake of not being killed by the world wide web I´ll put it like this: If you have a naturally aspirated car with low power in relation to the grip you have and also run on real racetracks where avg speed is higher than eg autocross etc - you actually don´t need a LSD. The LSD actually robs you from power (simplified). It tries to equalize the speed between the right and rear driven wheel (and will continue to do so until you are driving in a straight line) thus actually works against you steering input. So, everything else equal, you need to steer more (thus also slowing down more) in order to achieve the same rotation/turning radius, because the LSD tries to straighten you out. And the more you steer, the more speed you lose. Yes, some will debate that a "torque biasing LSD" instead of a "friction plate LSD" will have less of these tendencies and I could agree to some extent but then you have the case of thinking that you always have an LSD but you haven´t because both wheels need to be on the ground so it starts to become unpredictable because you can go from full "lock" to no lock, when you think you have lock. An open diff is very predictable, it will always spin the inner wheel if there isn´t enough traction and that scenario can be modulated with the right foot potentiometer. So, putting an LSD in this particular car, for driving on the Nurburgring, would actually make it slower. Yes, slower. "Then why do all "real" sportcars have LSDs" (and MX-5s do too from the factory BTW). - Well, I am not saying they are bad by default because they aren´t. I am just saying that in my particular application and intended use it would actually slow me down. In a daily driven car or in a car where I also want to drift around (dry or wet), AutoX or play around with in the local roundabouts I would choose a car with LSD, any LSD, every day of the week. And here is the plot-twist... I have actually considered an LSD. Why? Well, I like to have fun and drive when it rains on the trackday too. Since the grip is sooooo much lower in the wet, which is the same effect as having a lot more horsepower, the car would benefit from an LSD in those cases. It is also a safety-thing actually. If I end up in a wide drift because of any reason, it might be hard to hold it with an open diff thus I would risk one-wheel-spinning, getting grip in the back, and getting understeer that would push the front wide (read: Hitting the armco nose-first) instead of keeping the drift around the corner and continuing. So, what would I choose IF a go down that line? I would go for a friction plate LSD with as many surface areas as possible for stable behaviour and low maintanence but I would set it up to just do a tiny-tiny amount of locking. As little as possible. That bare minimum lock to help out in those cases in the wet or when jumping over curbs etc, but not robbing speed/creating understeer according to the explanation above. I hope you enjoy reading this. Kind Regards, Robert

Hi everyone, I see a lot of questions and theories reagarding my gearbox and it is actually pretty fun to read but I thought I could help out and clear out some questions marks. The car originally had a OEM 6 speed and can be seen driven with that box in other videos. Today the car has a classic 5 speed H-pattern and a different final drive. It started life as a standard NC 5-speed box but the gear rations inside are different than stock, they are closer. I only use 2nd, 3rd and 4th on the Ring and that is done on purpose. 4th gear is 1:1 ratio so the least amount of energy losses through the gearbox hence I want to have that as the top gear for all those up-hill sections etc. All other gears matches perfectly now with my increased rev-limiter and larger OD tyres (245/40 17). Yes, I could have put a shorted FD and used 3-5 instead but that would have been worse overall since I need to shift more ofter and will again run out of revs before braking points and have greater energy losses in 5th as it isn´t 1:1. No dog-box, no dog leg or any other animals in my MX-5 :-). I hope this clears out some thoughts... Cheers!

This is the cleanest lap of the Nordschliefe I have ever watched. Absolutely incredible! One to be remembered

This was great to watch and to see you drive it irl! Too bad you didn't have a passenger seat, so I could not stalk you for a passenger lap :p

Oh how I wish I could see the pass on that 911 at 2:17 from the Porsche's perspective. Dayummmm. Also, that GT-R was absolutely flying.

Holy shit you really are the definition of driver mod.

Ok who disliked this video? Was it a Mustang owner?

Legendary. Proper nice work with the car and the driving. CHAPEAU mon ami!

Great driving, man! I had a great time talking to you during the past 2 days, I hope we'll meet again. Thanks for your love for sharing and for being such a cool guy, keep it on!

This was so mesmerizing, I couldn’t stop watching, and the SOUNDS! Awesome👌🏼

when people say the Miata is a "girl's car" I'm going to show them this

you were catching that nissan gtr on corners

I keep watching this over and over again. You are a King!!!!

What an amazing performance, driving skills of the chart and the little mx5 seems to be exceptionally well tuned. Great job guys 😃

Unbelievable stuff. Robert's previous videos actually led me to buy an NC. Much love

Craaaaazy car and driver. That is so fast for a Miata! Looked absolutely fun to drive...

I find this really relaxing.

Fastest boat ever!!! brilliant driving 😍

Anyone notice his throttle to brake ratio? The man was on FULL THROTTLE almost the entire run!😳 He barely touched the brakes!😆 Wow! 🤯

I thought you’d never lift off the gas!!! Impressive! Car is a screamer! Love Miatas.

Epic. Just epic! Amazing driving, as usual. :)

The portion of the track that is done at full throttle is crazy! Very good grip from the car and incredible “courage” from the driver!

Love the superskill of the driver and the kinematics of the car! Thumbs UP!

Fantastic to watch, thanks for posting 👍

This must be one of the best, if not the best lap I've ever seen.

Terrific lap ...........thanks for sharing it !

Awesome drive , I love how the engine screams like it will explode any second but keeps going. I tracked mine 2.0 untill 177.000mi and swap to 2.5 now .

That's some incredible driving

Amazing.

Amazing to watch. Got some good tips off of this, im on a journey to improve my lap time in Assetto Corsa, I struggled to get a 10min lap time in the Miata NA, will put what I've seen here in to practice. Great HUD you put together for us too👌👍

Good to see you back at it! Superb drive

Wow. It's fun to watch someone drive a Miata to its limits. 7:37 is a great time. It's fun see how much speed you can keep in the turns.

Wow. Quite amazing lap.

Way to show the others how fast can a boat go with skill. Good work

Wicked lap my boy

This car made a short cameo in one of Mishas videos, the new roof looked interesting. Needless to mention it but, Great Lap !!!

I would actually pay to follow you for one or two laps. Very smooth lines!

These videos are by far my favorite on KZfaq. People ask me who my favorite driver is, I show them this channel. Edit: That has got to be a Miata record of some sort.

What a pilot! Bravo

That’s some great driving! Looks fun wringing that car out.

That's exactly how I drive the Nordschleife! The difference is, I do it on the Playstation and I if I miss an apex and crash the guardrail I can just restart the race... And also I'm slower...

Absolutely amazing 👌

amazing drive

Impressive mate - that's a clean lap ! This clearly shows you can make great performance without having 400 bhp... Congrats to the driver.

This... is.. awesome!! 🤤

This was great!

This is awesome!

I was watching on a big screen home theater, 4:32 took me by surprise 😂🤯🤯

Coming into that corner at 0:47 .... man you were flying, I’d have been terrified!

Brilliant drive mate.

The best mx5 ever! 🔥

This is unreal driving skill on display, as well as humungous brass...

It's so fun to watch good drivers on the ring ... that GTR scared me though ;D

Great driving!

In an MX5! I thought it was an aero type car. That was amazing driving!

Sick skills bro

Great vid!!! 👍😊

Great performance from both driver & car This video shows that you don't necessarily need a supercar to enjoy an impressive lap in the Ring

Dream drive, normally-aspirated, simply awesome…

No insects were harmed during the making of this video. :) Great lap!

That engine sounds amazing.

That sound!

Thank you for videos and comments ❤

u are my hero

Love the occasional fender rub.

Awesome driving skill there dude! The only thing I'd like to say is that I'd love to see an NA 20B rotary in there!

The lap time you set with so little done to your NC Mx-5 truely shows how incredible of a driver you are and the car's potential. Great eye openining experience and I feel more excited about my new NC Mx-5 as well.

Love seeing that there's at least 1 other driver pushing their car to the limit (GT-R).

Magic !

Masterful

Perfect driver!

Amazing driver

Good Job !

Beautiful lap. People like to clown on the NC but it’s got better bones to start with as a track car than the other generations.

Great driving skills! Would u pls share more pics about your car sometime?

So that's why an MX5 is so much fun.

I used to think the Mx5 was just a "girl's car". Videos like this are why the car has grown on me

Playing catch up with GTR. Nice. 👓

incredible..

Im speechless.

I was like "wtf, why this guy don't throw 6th gear?" then I read the mod list and discovered it is an 5 speed gearbox 😂 Sound great man, greetings from Mexico

This shows that with a car that barely breaks the 210kph mark, you can make some awesome time on the 'ring :) Driving pleasure can be found in any ride ^^ (that Skyline though hahaha)

The description of the shifting issue with the Max RPM Rangers pretty much an accurate description !!

amazing driver, amazing car.

I wonder what you can do with just a simple Turbo setup! Great driving, fucking love it

Serwanski was not the Koenigsegg test driver? Amazing driving! Congrats!

You can tell he really wanted to chase that GTR

It seems like an extra 50 hp would be perfect, that exhaust sound is awesome

Gonna go fast!!!

nice car tuning :) damm i want see the car from outside

Wow👏🏼

G A A A S Love it!

Wow incredible lap. I can only imagine how fast you'd be if you supercharged it! 😉

I like seeing him see something in his rear view and that pass @ 4:33

WOW!! I doff my cap to you...

6:35 awesome! grubo! :)

Robert: Smoking every car on the Nordschleife, including multiple Porsches That one GTR Driver: *I'm gonna stop you right there*

People in their VW GTis telling me MX5 Miata is not a sports car

Awesome lap. I've got a NC Open Race for trackdays. And have some questions regarding your ECU remap. Which supplier? And how did you change the rev limiter?

Wonderful sound. Good driving.
