which means the 275s on the back, picking the correct rubber makes a big change
Has anyone tried Pirellis P Zeros on the GT, I hear they stick like glue..

I have 275 Sport max Dunlops on the back of my 335, as used on the RSpec. The difference between them and the original 245 Dunlop 9000's is staggering. It's gone from being twitchy and being unable to use more than 1/3 to 1/2 throttle in the lower gears, it would light up tyres at 80+ kmph if you stood on it. To being more like a normal car. There has been no other changes to the car. So wider better quality rubber works. Is anyone surprised?
