If I switch to the 265/295, can I stay with the 18" wheels and 40 profile without any problems? The tires will not extend beyond the wheel well?
I should also note I have the Dinan Stage III suspension--the camber plates and springs do make a big difference--the larger front antisway bar not much on the street, but some improvement at autocross.
No, you will need to switch to 35 profile.
295 will be too wide for the 9.5" rear rim (You will lose steering response) and you are better off maintaining the 20mm stagger to keep the tire diameter stagger the same (DSC will cut in more if the stagger is increased).
The difference between 245/265 and 265/285 is very small, by the way. You will lose steering response and gain a bit more total grip.
