[Cbra 65]

I raced formula cars for thirty years and felt my Superformance 427W was dangerous on street radials. Goodyear Bill Boards made a real sports car out of it. They don't damage the body any more than the radials. I'm lucky enough to be able to keep it on a lift. The first time I left it on the ground for two days I thought I had square wheels for the first mile or so. They aren't street legal but, you can go 200mph on a track with them without a problem.
