I have been running Michelin PSS 4S tires for two years on many autocrosses, and they are starting to get heat cycled. The only modification to the car is the 32mm bar in the rear, which took out all of the understeer. Im wondering for my next set of tires if I should stick with the 285s or go up to 295s. I plan to keep the square set up as it worked very well for me.
Is Pete still around?
