Stock diameter is at least 26.8" and now you have 28.4" front. Rear is 26.5" and now you have 28.3". Something tells me you need a different stagger setup. Or settings on sways will help.

My set up is only about 2.5 % taller than stock so its not much. However the front tires got wider (percentage wise) than the rears. From 245 to 265 and on the rear from 275 to 295. So in theory it should help eliminate some of the understeer.

Something i forgot to mention was tire psi. It was front and rear at 35 hot. Next time ill try to lower both. And have the fronts a little lower.

You definitely want to square off your tires on the car, as was previously mentioned. Going wider all around is just keeping the car right where it was.

I run a square 275-18 setup at the moment, and it's incredible.

All due respect, while you may like where the car is right now, once you go square (or close to it), you probably wont go back at the track with the 370, at least...
