I need to dial out the oversteer and was looking the Weltmieser front saybar for that. Or would a M30 front bar with a stock back bar work? Leaving the back softer, will that help to take out the oversteer? This is mainly a daily driver, but will go to some DE's so I'm not looking for a full track setup.

As far as I knew, our cars have a fair amount of understeer with the factory setup. Have you modified the car or are you running larger tires?

I am hoping that increasing my front tire size to match the rear will dial out some of the under steer!

I'm running 17 x 7's on front and 9's out back 225 45 and 255 40's RE11. I have less over steer with this setup. The back is siting lower than the front. The front looks like it's setting a little high. And Koni yellows in the back with LSD. I installed the front swaybar upright brace that was installed over the winter, but the rest is from the PO. The front has a 2" from the fender lip to the tire and the back is even. I think the front sould be droped a inch or so but not sure I want to run Koni yellows for a daily?

J Berk

Interesting.

I run yellows daily. They have about 3000miles on them now. Set to a middle setting.

Stock 16" wheels and I generally run the factory sized tires.

car is not mo30....and the only other mod is the kla strut tower brace.

Pretty neutral towards understeer .....not a hint of oversteer.

What are your alignment specs?

mopar bob

Not sure on the specs but it needs to go in this week for a check with the new tires.

Your rear is too low and you are riding the bumpstops, which is causing the oversteer. Ask me how I know.

Cheers,

What do you think about these 2 springs to drop the nose of my car. I don't want to drop it to far, I need to get in and out of my driveway.

Progressive Sport Springs that drop the car 1" and has a spring rate of 190 - 230
or the Weltmieser drop spring that drop it 1.5" that has a fixed rate of 200

I will also reindex the rear bar to raise it 1"

There can be alot of reasons for oversteer many of which result from having something wrong on the car. Before you start throwing parts at the issue I would understand how the car is set-up now to understand where the oversteer may be coming from. My bet is you can fix it with no parts and just a little time.

M758

Possible, but I drive a fellow racers car that was doing just that. Very odd feeling as the car transition from "fine" to "woah". Not your normal oversteer . This is one reason why it is important to know where and when the oversteer is occuring.

On track or on the street. Corner entry, corner exit. on power? off power, slow corners fast corners? Not knowing this just shooting the dark. Then we need to know tire pressures, alignment settings, driving style etc.

I work with alot of 944 racers who have handling issues. Fixing the car is impossible until we get some basics down.

In general lowering the front and rasing the rear will cause more oversteer. Rear end low should cause understeer especially at corner exit power on. So changing these parts could solve your problems or make the worse. It really depends on what the real problem you are facing is.


Like I said throwing parts at this issue before you understand what is happening is great way to screw-up the car pretty badly.

mine is pretty balanced, it over-steers in some spots and under-steers in others.

Joe is right on the money. So much depends on where you're getting oversteer, and what you're doing when it happens. If you're braking late, and getting oversteer going into a turn, then a driver adjustment is probably needed.

If you're getting oversteer while you power out of a turn, then a suspension/alignment adjustment is probably more in order.

It looks like the rebound on the struts are not great so I'm looking to upgrade. I wouls love Bilstein PSS9 for my car but it looks like they are not made any more for the S2/968. So it looks like it my be Koni yellow's with Weltmiser 250lbs front springs that drops nose a inch or so. Or is there some thing better for a daily driver that does some DE's

M758

Again throwing $$$ and parts the problem.
