in testing i found that it mellows the car down quite a bit.i run mine at 168mm and it gives me the feel that i am looking for.i tried more narrow and the car was darty feeling.i went to the roar limit and the car pushed.it controls the amount of rear traction and the rotation.more narrow the faster it seems to rotate making it a bit of a handfull.
