Well after searching for used wheels all over the forums and trying to find the right sizes/offset I decided on getting the MB Battle 18×9.5 +15 offset directly from Discount Tire. I found an online coupon for $100 off per set of 4 wheels and I bought 2 complete sets at $648 each and free shipping!!!!!!! I ordered an extra set though for the Time Attack Silvia S15 (as spares) were building to compete in Redline Time Attack this coming year.
