Try this -- Bullittproof01 put it on a while back ... tested a bullitt, cobra, and mach 1. The bullitt just drives way better than a regular GT. The frame supports, lowered height, improved braking, etc. just makes it a better (faster) driving car. Bullitt is better in the twisties than the straight line, but is still no slouch when you don't have to turn.
