Griggs racing has just rolled out a new suped up version of the Ford Mustang GT. They have billed this “the ultimate vehicle for track days.” What makes this car different from the others is it's capablities on the track.

The GR40 features a 4.6L 3V supercharged V8 that pumps out 547 hp 463 ft/lbs of torque and a highly modified suspension: trademark SLA suspension, Koni coil-overs, heavy duty Torque-Arm, adjustable Watts link, and Griggs “4 on 4” competition brake system with ABS.

I always wanted a muscle car stricty for the track, this car looks like it could be the one.
