How can I reduce oversteer without spending $$$ on swaybars and extras for my car.
Should I upgrade the tires, and wheels?
Do narrow front wheels, and wider rear wheels cause oversteer?
Is it Narrow Rear wheels, and wider Front wheels that cause oversteer?

If I go from Stock AP1 dimensions, and get myself a set of wheels and tires,
will I experience more oversteer with a setup like:
Fronts - 225/40/18 Rear - 235/35/18

Or, will this reduce oversteer?

Thanks.

 

big sway bars cause oversteer. yea skinny tires in the rear will reduce a little.

 

I believe s2k dre is wrong. You need narrower front tires and/or wider rears. A wider front tire will add grip to the front and make it easier to lose the rear. Adding a wider rear tire adds grip at the rear and should make it more difficult to slide the rear. As for sway bars, a rule of thumb, if you one end of the car is sliding stiffen the other end. Oversteer, stiffen the front. Understeer, stiffen the rear.

 

fatter front tires give the front more grip and reduce understeer and increase oversteer.

 

i got smoked on this one.

 

Thanks!

 

Do you want to reduce oversteer without spending $$$ ? Slow down!


To reduce oversteer you need to gain traction on the back and/or loose traction on the front. There are many ways to do that (tires, bars, suspension)
Good luck

 

To Quote Willie Gee
"Oversteer is when the passenger is scared, understeer is when the DRIVER is scared"

To really oversimplify, understeer is a loss of traction with the FRONT tires and Oversteer is a loss of traction with the REAR tires.

 

Properly set up (ie, correctly sized tires and a good alignment) the S2000 is a supremely neutral car.

What are your goals? Does your car tend to lose the rear end a lot? It is your driving style that is causing the oversteer? Have you had an alignment recently? How about tire condition? There are too many variables here that need to be sorted out before labeling the car as "oversteery".

 

My cheap solution on the track without any kind of hardware modification is adjusting the tire pressures.

Just make sure your rear tires have slightly lower pressure and front ones slightly higher. This way the contact area of your rear wheels will increase and front tire contact areas will decrease. This should help make the butt of your car stickier.

Play around and see how it feels to you. Just make sure you don't over-inflate or under-inflate your tires.

This is the cheapest way of adjusting over/understeer.
