[V6Convertible]

I recently purchased some Saleen replica Rims

18X9 for the front
18X10 for the rear

I autocross the car regularly and intend to purchase the stickiest street tires I can get for the best price.

With the wider rear rims I could run wider tires on the back, but I have heard this could increase understeer. Any feedback on that would be appreciated.

I am considering Kumho mx's as they seem to be excellent performance for the money.

I dont drive the car much except too and from the races locally, So wear is not as important as performance.

Ill Be racing in Street Modified where my competition can run race tires, So Im already at a disadvantage.

I orignally purchased the wider rear tire because Im running a supercharged v6 with 4.10 gears , I thought bigger tires on the back would help prevent wheelspin, and the more rubber on the road the better.

However in my last autocross race I learned that due to understeer that mustangs can be "steered with the rear tires" effectively, using a little drift to bring the car around corners.That make sme want to reconsider putting bigger tires on the rear.

The Car has the following Mods

Steeda sport springs
x2 ball joints
bumpsteer kit
tokiko illuminas all around
Vortech V1
Magnaflow dual exhaust
SCT chip(dyno tuned)

any other autocross advice for the 95 v6 convertible would be appreciated.
