Fronts are 205/50-16 on 16x7 Torq Thrust IIs with 4 inch bs.
Rears are 245/50-16 on 16x8 Torq Thrust IIs with 4.8 bs. Eventually we'll go to 17x7 front with 225/45-17, 4.75 bs and 17x8 rear, 245/45-17 with 5.25 bs. The current wheels work, but rub occasionally, like when turning into an inclined driveway. If I had known they'd be that close, I'd have gone with the 17s and more bs to start... live and learn.
The engine is a 318 with stock manifolds and 2.5 inch dual exhaust. The exhaust was done by the PO and hung really low. We had to do some finessing to tuck it up enough to not hit on speed bumps. We have a 383 that came with the car we plan to go through and install eventually. It'll get Schumacher shorty headers and stainless exhaust tucked up right when that happens....
