In this month's Prancing Horse (#150, 1Q04), there's an article on the first Enzo sold in the US... to Bob Rapp. It mentions that he "had competition belts from Ferrari installed so the car could be used on the track -- another $1,000." Competition belts? What are they? What do they do for track performance or reliability? And do all track-bound Enzo owners have that done? And are there competition belts for other Ferraris? For the 360? For the CS?
