Anyone know?

Or is Stiffened suspension the answer to stopping the rear from going so light on lift off?

I don't think it will eliminate "snap oversteer".

A sway bar will tighen up the front end of the car to help compensate for oversteer. Some S2000 members say that a sway bar will help with the 4 wheel slide.

I have not tried a sway bar yet...but I have done the "snap oversteer" in an autocross. But, I believe the "snap oversteer" is caused by the driver.

Hi ced!

I am talking about this whole 'tail-happy' discussion. wondering if when the weight transfers from the rear to the front when lifting off the throttle, the weight transfer would be reduced or at least the effect of it reduced if the suspension at the front is stiffer.

someone else I think UKPaul said he is going to buy a sway bar following his spin. I dont understand what a sway bar does thats all.

What do the comptech coilovers do for you??

like the red calipers! are they new or painted? where did you source the solution?

do the wheels alter handling?

The sway bar will not affect back-to-front weight transfer. The purpose for a sway bar is to keep the car from rolling (swaying) side-to-side.

A sway bar will have no impact on weight transfer. If you shift the weight forward for any reason you will reduce rear grip and if it is at the wrong time the rear of the car will come around. This is how all balanced cars work, although some transition more slowly.

Cars that respond quickly to the driver do it quickly to bad as well as good inputs.

The sway bar reduces body roll at the front suspension. Without a change to the rear this shifts the handling balance a little to less oversteer and more understeer under some conditions. It will change the feel and add some control over the rear drifting out.

It will not stop spins induced by overpowering the tires in a turn, forward weight transfer (by reducing the throttle or braking), gross application of steering, cold tires, and wrong speed or line.

The bar is an improvement for some driving but will make little difference for many. It likely will not compensate for errors in judgement or make the car easy to control at the limit.

I'm with cdelena on this one. I feel it improves handling greatly and reduces the tendancy to oversteep in general. It gives the car a more solid front end feel and more uprite stance. Turn in seems quicker. It wont compensate for driver error like overcorrection, slow reflexes or poor judgement. It simply raises the bar (no pun intended) but misjudgement will still get you in trouble regardless. If you notice, the issue of snap oversteer has deminished lately. I think is was a result of the car being new and unknown.

The stabilizer bar is excellent I highly recommend it. One thing I've noticed is the ride is smoother, less harsh. It's not just me either. A good friend who has spent a good deal of time in my car mentioned it too. It's money well spent IMO.

where did you get the stabiliser bar from?

How much was it to buy and to fit?

does it in ANY way reduce the handling of the car?

thanks all for your replies so far - i must say that the only time mine has stepped out was when i powered it round on a bend, it surprised me when it came round much quicker than i had expected. I corrected it easily and have been cautious in the wet on bends since.

My concern is that 'emergency situation' where you have to react in a split second and being without 'serious' driving expertise i want to have all the odds stacked in my favour. anything that i can add that wil improve the odds i want to do.

There is a dynamic here that people tend to miss... statements like 'a front swaybar will not affect front to rear weight transfer' is true only with the car at rest. Once you put a car in motion, these parts all work in concert as forces work on the whole car. By preventing front body-roll, the front swaybar resists the inside rear wheel lifting - thereby limiting front to rear weight transfer. This is while turning the wheel and entering a corner. Remember that any changes to the suspension must be visualized with the vehicle as a whole.

There are two types of 'snap oversteer' that are being discussed, as well. One is a lift-throttle oversteer that happens entering a corner due to weight coming off the rear tires. The other type is under power and exiting a corner. This is the trickiest type of oversteer in this car in my opinion.

What happens is the rear of the car starts to lean in the corner. As you exit the corner and power is applied, the rear of the car squats which makes it grip really well. This grip continues until one of two things happen... the outside rear suspension bottoms out or the rear wheels break traction. Then the back end swings out unpredictably.

The front swaybar will help both of these problems... It will not only control front body-roll, but diagonally control rear body roll due to the chassis stiffness.

The other way to avoid the snap by changing driving style is to gently apply the throttle exiting corners. This never squats the back end so much, and then you can keep the rear under control. It will starts sliding right away instead of suddenly and you can control the rate at which it slides. Go out and practice in a big open parking lot... first in 1st gear, then in 2nd. You'll feel the difference when you go easy on the gas.

That being said, the Mugen bar will only make things better! HTH
