Wheels are Rocket Racing Booster wheels in a Hyper Shot finish. Size is 17x8 with 4.5" back spacing all the way around. The tires are Michelin Pilot Sports. I haven't driven it yet outside of my drive way. Have to fix the kickdown on the transmission first. It fell apart when I did my borgeson gear box. Had to order new parts to fix it because I think my wife swept the parts out of the garage! That said, I have similar tires on my 2007 GT and they are awesome. My 07 has about 600 hp and these tires hook up pretty quick on a hot summer day, plus they are excellant for track days. The old tires on my GTCS were rotten so anything is an improvement! It was like roulette driving that car anywhere! Just waiting for them to blow out.
