I picked up a set of Lotus Cup wheels for my 2006 Elise this past fall and am looking to order a set of tires for the upcoming track season. The car is supercharged but stock suspension (non track pack). I drive to and from my local tracks and put street tires/wheels on when at home. I ran R888's last year but am unsure of the right size tire for the cup wheels. Thinking 205/45/16 for the fronts and 235/40/17 for the rears. Anyone else running that size or any other recommendations?
