I have adjustable suspension, and im torn between two sizes for track driving. Either 17x275 front and rear or same size wheel 255/275 RA-1. The car is on 265/285 right now, and it feels like it tends to oversteer. But when i was at the track it didnt as much. Which would you sugest.

 

I suggest getting the same size tire all around to save money since you can rotate them and increase the life of the tires.


Do you have the same size rims front and rear now???

 

no as my post says i currently have 265/285 and its slightly biased to oversteer,

 

Are your current rims the same size front and rear?

 

I have been running a "Square Wheel/tire setup" in 4 track days...and I really like it....17x10 wheels with 275/40 Toyo RA1s all around

very neutral turn in, and good cornering speed

However, I do get some oversteer, but you just have to drive the car knowing that it is there. So I tune my sway bars on different track to help me compensate for this....
