Middy oversteer
Lightning - 6/3/11 at 06:57 PM

Just let my mate drive my car. He put it into a roundabout and spun it. I have noticed myself that it does rather dig into the corners. What could I change to reduce the oversteer?

Just got the thing back on the road after modifying the exhaust. Now reads 95 dB at 7500revs....result.

Ease off the throttle?

Good point. but not what i had in mind

Lol,

Have you looked at your camber on the rear? Suspension setup may be a little unforgiving. Try softening it up a bit.

Dont let anybody else drive your car

sorry no help, i guess its going to be a case of changing sping rates and damping and tracking, its going to take alot of time and money i fear

He should have known better being on traffic. There is a fair bit of camber on the rear . It is adjustable could reduce it a see what happens.

What toe are you running on the rear? Toe out will increase oversteer I think.

As you say its digging in, I take it its enduced by weight transfer under breaking/lift off rather than transfer backwards when accelerating out of a bend?

Tyre pressures - more at front, less at rear
If you have single adjustable shocks - soften the rears, stiffen up the front end shocks (lessen the weight transfer to the front),
If you have double adjustbles then soften the rebound on the rears, stiffen the bounce on the fronts.

(PS this is based on computer game set up, so pinch of salt to be taken - LOL)

Stiffer front antiroll bar or springs

A slight adjustment to camber will make quite a difference. How is it set up at the moment?
I run about 1 degree front and 1.5 degrees rear - I can drift if I really try to hang the ar$e out but it is controllable.

I would set it at "0" and see if that makes it any easier to drive. Then you can start making 0.5deg incremental changes.

Thanks for your input guys.

I will try different things as suggested but one at a time and note the difference.


I'll try tyre pressures first as thats the easiest

Hi

Actual static camber settings are one thing. WHAT is happening to the camber during a corner / roll situation. You may find that it is heading in a Positive direction and reducing the camber rather than pulling more negative camber on. You need to know the answer to this before making any logical camber settings.
