Are you thinking of track time or club racing. If it's just going fast and racing the clock, slap some sticky tires on the stock rims, aftermarket sway bars, camber bolts, get race pads and cooling ducts and have at it. The 370Z is quick as well but has horrible overheating issues. A competitor of mine had one. Put an aftermarket cooler on everything and still went into limp mode on track from overheating. The transmission I believe, even with a trans cooler.
