My 350Z. This is my real love. It's such a bad ass car but its only a summer car. The S4 is my all round sports car. The Z is the summer toy and what a great car it is.
Wheels are; Front 19" x 8.5 (245/35-19) and rear 19"x10 (275/35-19) Just rolled my rear fenders so a 295 will go on the rear next year.
Puts down 272whp normally aspirated with headers, exhaust, intake, IM spacer, ecu flash, lightweight flywheel/clutch, etc. Also has full suspension (hotchkis) with sways, 13" bbk and a bunch of other toys.
