check out the video of Skunk2 FitR at Willow Springs Raceway (Fastest Track in the West)!
The Skunk2 FitR uses Skunk2 Pro-C coilovers, Kraftwerks Supercharger Kit, and 60mm Skunk2 Megapower exhaust.
This little car was holding its own against some really exotic company and was actually running faster than a BMW M5...that video will be out shortly.
