LV,
If you think the car oversteers too much you can fix that by a number of means.
The following is an excerpt from
Air Pressure for Competition Tires from Tire Rack's Tire Tech section.
Guide To High Performance Handling
Adjustments...................Decrease Understeer......Decrease Oversteer
Front Tire Pressure...............Higher..................... .........Lower
Rear Tire Pressure................Lower..................... .........Higher
Front Tire Section..................Larger................... ..........Smaller
Rear Tire Section..................Smaller.................. ..........Larger
Front Wheel Camber.............More Negative..................More Positive
Rear Wheel Camber..............More Positive....................More Negative
Front Wheel Toe....................Toward Toe-Out................Toward Toe-In
Rear Wheel Toe....................Toward Toe-In..................Toward Toe-Out
Front Wheel Caster...............More Positive....................More Negative
Front Springs........................Soften............. ................Stiffen
Rear Springs.........................Stiffen........... ..................Soften
Front Anti-sway Bar...............Soften (Thinner)...............Stiffen (Thicken)
Rear Anti-sway Bar...............Stiffen (Thicker)...............Soften (Thinner)
Weight Distribution.................More Rearward................More Forward
First I'd try dropping the pressure on the front tires 5spi and increasing the pressure in the rears by 5psi, giving you a 10psi difference front to rear. If this starts to give you the results you're looking for you can step up to these changes that may give you bigger dividends.
Increase the rear negative camber (I'd start with half a degree).
Increase the rear tire section width. (You'd have to get a wider rear wheel to do so safely).
Those 3 things should make a very significant difference.
