The Car

The Mule side profile

The Mule is the test bed. Parts get tried here first, and whatever survives goes on the cars that matter. Everything else gets left in the paddock as a lesson.

An N54 intake manifold, catless headers and a 22RPD tune do the work up front. Weight went out in every direction until it dipped under 3000 lbs. The sway bar is fitted, solid, 28mm, and completely disconnected. It stays that way.
