What is a strut bar? How does a strut bar work? What forces act on the strut bar through the suspension? A strut bar, or tower bar, connects the top strut towers together, in order to increase the rigidity of a vehicle by allowing both strut towers to react to compression and tensile forces. A strut bar plays a larger role for MacPherson strut vehicles, however it can still be important in vehicles with double wishbones as well for compensating vertical forces.

It doesn't act as a sway bar, it simply keeps the body a bit more stiff. Sway bars are used to reduce roll, which is not what strut bars are used for. I have a video on sway bars if you're curious.

Correct, the MacPherson strut is load bearing of the forces from lateral acceleration, where as a double-wishbone handles the vast majority of the forces through the control arms. Of course, the weight of the car, bumps, and weight transfer by cornering still put additional pressure on the coils, thus a force on the strut tower.

Strut bars works well in Macpherson struts. One reason why? Because car manufacturers now, have placed strut towers very near the firewall where they can bolt a part of the chassis (usually at the base of the windshield) unto them. Acting as a strut bar on mass production cars, like a Honda CRV or a Nissan Sentra. So yes, buying and installing a $20-$50 aluminum strut bar on your old car is NOT a waste of money. Even if you don't use it for racing, it does make your chassis a tiny bit tighter for maintaining the correct geometry that can go a tiny bit off thru the years. Take it as an investment not as a racing mod.

Otherwise yeah, I don’t see why it wouldn’t help, even if just a tiny bit.

Ok. Ok. Thank you very much for this post! Until today, I had no idea what a strut bar was or what it did. We have a PT Cruiser and the previous owner installed a strut bar (Alutec UltraStrut) that is welded right beside the strut bolts, as you indicated. My problem is it goes directly over the power steering reservoir which means I can't open that reservoir to check it. It almost blocks the coolant reservoir ▬ but at least I can open that one.

On any car with shock towers and unit body construction, some flexing will occur. An upper strutbar is mostly for show (and adds weight) and only partially effective unless a lower bar is used to tie it all together; essentially you are boxing the suspension as a true frame would do. Upper and lower A-arms are the best means for keeping tire contact and have better travel (and respond better to lowering springs).

Cheers to your ideas and opinion. Cars are carefully engineered for purpose, appeal, and a certain lifespan; but it's a business, so compromises are made. Simply, if something minor like a an upper strut bar really added so much precision, and hence safety, to the suspension then it would be found on more cars wouldn't it?

elliot438bcfc I see. As far as strut bars/braces go, the baseline you seem to have for your car's handing is NOT without those parts in place. I was hoping to know if all the strut bars were installed by you and that's what improved the handling. The improvement you have achieved seems to be mostly due to the coilovers. Of course, I am only deducing that from your comment since you are the one who drives your car. However, if all the strut bars (save for the H brace) came as stock, the car actually needs them to handle well and would not be as poised without them. I wonder how much of an improvement a strut bar provides in real world circumstances in a car that does not come stock with it. All theoretical questions I guess...
@elliot438bcfcVTEC
@elliot438bcfcVTEC 8 жыл бұрын
Siddharth Rajkumar I believe strut bars will have a small effect on handling. I don't think Honda would put them there for no reason as they made the car to be as light as possible. During hard cornering (providing grip is adequate) there will be flex and strut bars will definitely lessen this flex. Similar to how brake stoppers work.
@siddharthrajkumar7619
@siddharthrajkumar7619 8 жыл бұрын
+elliot438bcfc That makes sense. If they made the shell of the car as light as possible, that means some load bearing parts (like strut mounts) might flex under cornering stress. To make up for that they must have installed strut bars instead of adding large areas of thicker sheet metal. Brake stoppers? Do you mean bars or link rods that connect the chassis/body to brake calipers to prevent them turning about the rotors?

Great video describing the suspension load forces! A strut bar will definitely help stiffen a McPherson strut suspension vehicle, but at the same time it will increase ride harshness, noise and vibration. I put one on my 1984 VW Jetta GLi coupe, and on harsh road conditions, it sounded like someone was hitting my dash with a sledgehammer. Unless you track your vehicle or have very smooth roads where you live I wouldn't recommend them in daily use. That said, I did mount a lower control arm brace and a rear strut bar - those helped the vehicle corner better without any increase in NVH.

I haven't installed the catback because I want to do engine upgrades differently - I want to prove they've made a difference, which requires dyno testing. I want to be able to tear apart my car and leave it in a garage, without needing it - which requires another car. This should all be solved within a year, as I'm saving for a new car currently. My channel grew a bit faster than I expected, so I'm just trying to keep up!

I don't see it making a huge difference, unless there is considerable flex in the strut towers upon lowering the car back onto the ground. Regardless, if installed once lowered it will attempt to negate any force which differs from the car when it is stationary. The bar will experience compression and tension, so pre-loading it one direction (which could be the case if installed while lifted) may not always be best. Interesting question though - feel free to expand anyone...

This is a good explanation of the concept for the layman but you could have gone further by explaining how compliance in those fasteners/threads, how those steel brackets are hilariously cantilevered away from the load path make a two point bar a very very marginal improvement, if any, in the handling dept.

A street car doesn't NEED a lot of things, but people do them anyways. Like a blown 800hp 3mpg camaro or a civic with a giant turbo that doesnt spool until 5k. You can make whatever choices you want and ultimately it comes down to what car you have and what you want to do with it. but me, id save the money for just about anything else over a 3 piece, 2 point strut bar. It was more a comment hoping they would have explained some real engineering concepts behind chassis stiffness and take things a step further than the standard explanation you can get on any forum and why people continue to have people buying up those useless 2 piece bars. I think you'll find your strut bar is mostly just in the way for a street car (it was in mine)

Since we're talking street cars, triangulated braces aren't all that beneficial to them. The firewall isn't a strong point for mounting something like that. A basic design, solid sway bar would work better unless the firewall was reinforced. I've yet to read any positive feedback from tri-braces and just looking at the overall design, you can see that as a corner is moving up/down it will be pulling that bar, and therefore firewall itself, to it.

+Engineering Explained Does adding a strut bar to a car reduce or increase stress on the original chassis? Basically, would it prolong a chassis's structural integrity or the opposite?

Alex Yang depends on how you drive. increasing the rigidity of the vehicle puts more stress to the tires. I noticed this after I put a front sway bar on my 96 corolla. I got wayyyyy less body roll but noticed my tires wear faster. then again the increased stability gave me more confidence to corner faster soooo it's debatable.

Dear Engineer, the force analysis of mechanisms can not be performed like your ıntiutive approach. You should first learn degree of freedom of joints. A revolute joint as in chassis side of the lower control arms has one freedom in rotation along its axis and there can not be a moment reaction which you wrote as "friction moment" thus your all analysis is wrong.

What youre talking about? the pivot point of the lower control arm is not coincident with the friction vector... therefore there MUST be a moment created lol

You've missed something, the most important function of a strut bar is to increase rigidity of the chassis. When you corner or hit a bump, the chassis will compress and bend slightly between the struts, the strut bar is there to minimise the compression, hence improve rigidity.

Street Car - Don't touch the suspension, you just make it worse. Race Car: Double Wishbone Suspension - Don't add any strut bars, MacPherson - Maybe. Few Important concepts are missing in the video: When you tighten up the front by adding a tower brace, you make the car tight. More Understeer. When you tighten up the rear, you make the car lose. Oversteer . So you are screwing with the balance. Adding of a strut bar very often makes the car handle worse, and it always makes for a stiffer ride. When you add so much bracing to a car, all the sudden the car is so tight it mishandles on uneven roads (Most of US). This works on a track to a point, but even then it can get too tight. None of my race cars ever had strut bars in them. Street car - leave it the way it is. People spent hours at the factory trying to make a balanced ride for you, and you want to throw their work out the window in few minutes. There are situations where a use of a brace could make sense. For example: Toyota Supra has a huge understeer by default. Adding a brace to the rear will give you more neutral balance.

Russain Guy Gang the presenter is explaining the use of a strut bar. struts are fastened or installed in car’s steel plate rather than bolted in car’s chassis. struts installed in car’s steel plate body gives a bending effect on the plate and that’s where the bracket comes to its purpose. My question is, how can a strut bracket eliminate that bending effect on the plate when he the presenter uses a folding end brackets? is it the purpose is to make the struts rigid in order to hold the struts swaying movement? please help me understand the purpose.

Loony Linn Exactly, most off -the-shelf strut bars pivot at the ends because the bolts holding the bar are horizontal i.e. the same rotational placement as the exact motion it's meant to stop. You want a strut bar where the bar bolts in vertically through the brackets. Alternatively, I suppose if that's all someone had available for their car, then the brackets could just be welded to the bar.

Street car: leave it the way it is, people spent hours at the factory trying to make an UNDERSTEER prone ride for you... Fixed it for you... almost ALL vehicles (unless you are buying a halo model sports car that is factory tuned for performance) will have a suspension tune that is biased towards understeer. Which is not a BAD thing, as most point A to point B drivers will never take a car to its handling limits unless they are trying to avoid a collision... understeer is "SAFE" Now, as a driving enthusiast, you know - a car tuned for neutral handling or a small amount of oversteer is the faster car in the corners. Being able to rotate the car in a corner and correct with a dab of opposite lock is more desireable than plowing out of a corner, or worse, plowing out, lifting off and spinning the car... if spirited or track driving is your thing. Just saying, the engineers that designed the suspension in most cars didn't set it up to handle at its absolute potential. they set it up so the soccer mom that will flip the hell out if the car unexpectedly rotates in a corner and crash...doesn't Also not saying a strut bar is the answer to any particular question. I tend to agree that they are largely un needed... unless it is. I would argue the point that alot of modern cars tend to handle better when pushed to the limit when you install a stiffer than factory rear sway bar...
@Akiss

No, understeer is more complicated than simply being "loose" or "tight," or it being bad vs good, it's way oversimplifying the dynamics. The short of the answer is the function of the body is to be rigid platform for the suspension to generate consistent grip under load. If you're talking street car, there's no way it "mishandles" on even roads due to it being too tight. Street cars by nature are underdamped for comfort. Plus, strut bars are about reducing unregulated, sloppy motion. Actually, now that I think about it I think you're confusing strut bar with sway bar. Even assuming it's creating understeer, there are a million ways to offset that, like more camber in the front, stiffer rear sways, heck even changing front/rear tire pressure.

Coming from someone that has been through 4 suspension setups in his Focus ST since he blew his original monroe struts 2 years ago I can say you may be right. Unless you plan on having a race team to adjust your ride height, damping, preload, and camber in my case on both front and rear plus adjustable sway bar link all atound and adjustable control arms in rear...my car catches a dip and literally launches itself up and back down so hard yet its semi controlled so I guess you can say it works but it iant ideal. Roads suck and unless you plan on driving your car to the track and adjudting it there I would leave things alone except for maybe a mild lowering spring at most. Even that is playing with fire. I am up to a 1,000 set of coilovers, my second set, and have tried multiple adjustments and even brought it to every shop in town. I am gathering parts to put it back to stock and will be selling all the crap I wasted money on for half the price on ebay. The car is so stiff its jumpy and what sucks is there is enough adjustment in it where you could probably raise it up and adjuat the coilovers to a softer setting and get away with that but between me and the people at the shops around here it seems to be more of a hassle than they are willing to deal with. I cant even get my mecjhanic to replace parts on my car until they are noticeably bad. He wont replace struts that has 60k miles on them that he thinks are fine. The rears were leaking at 30k miles and replaced by factory though. What a joke.

@romansoroka6662 6 жыл бұрын
lampim. Agreed. The car might feel a bit "tighter" as the slight ( as in thousands of an inch) flexing of the strut towers would be reduced, but actual lap times would be the same. The crap ones shown in this video are weak at the brackets, as the brackets extend upwards and can flex themselves. The bars are bent, which in itself is a weak design. And the brace is not triangulated to the firewall, therefore the strut towers could technically flex front to rear. Mostly rubish! If your strut towers are flexing that much, the car is scary weak.

Its not marketing some of the times. The fact is... It will depend on the quality of the bar but most important the state of the car. A 10 year old car might notice a huge difference, while a 1 year car wouldnt notice difference at all. Strut braces are also used on racing.

Sorry to say this, but my struts that had a little over 80k miles, felt newer after putting on my strut tower brace bar. But now, I have been riding on Koni yellow sport shocks and struts with that same strut bar. It is even more wicked of a ride. Oh... and I put them in my vehicle myself too! Even modded my car to accept the Koni yellow sport struts to go onto, since Koni doesn’t make their yellow sports for it.

Greetings. First let me say that It has been a great help watch these videos. Now, if I want to make a homemade strut bar, I know that I should consider the calculations of the axial stiffness for positive and negative forces (compression and tension). By selecting a few young’s modulus only would need the cross-sectional area and the length of the element, and that would allow me to calculate K (Axial Stiffness). Know my question is. If I decide to add a screw in order to make the bar adjustable, how can I use the formulas of deformation in X,Y,Z along with the Poisson constant to determinate what kind of screw do I need that can resist the forces?
