I was running 14" stock rims with cheap Yokohama tires (purchased the car in early August with this configuration) until last Saturday.
I now run:
FRONT - 17x8 Torq Thrust II Polished one piece (505 series)
REAR - 17x9.5 Torq Thrust II Polished two piece (405 series)
FRONT - 235/45/17
REAR - 265/40/17
Originially I tried to install 275's on the REARS, but the inner tire would RUB on the inner wall whenever I turned, even in low radius slow speed situations. The RUB was more prevelant on the driver side rear than the passenger side, leading me to think the rear alignment is slightly off.
I was going to add spacers to the REAR to make the 275's fit, but then I would also have to change my wheel studs as the stock ones are not long enough to accept a 5/16" spacer in-between the wheel and hub. Also, I bet dollar to donuts the outer fender would have started to RUB. The new STUDS would have been Dorman 980481 - 7/16-20, 1.75 inch, .475 knurl, 27/64 shoulder. The original is .472 knurl, but they don't make them in 1.75 inch, nor do they make them with the original 11/32 shoulder. But the 980481 from dorman would work fine.
That said i will be installing new Edelbrok IAS shocks to eliminate the remaining RUB on the REARS altogether.
I have NO RUB in the REAR on the outer fender, but I do have very slight RUB in the FRONT on the outer fender when I smack a really hard bump. Nothing special.
