Ron,
Tom Upton has been racing his Pantera in CVAR for years. It's a Group 4.
Corinthian Vintage Auto Racing.
I have recently joined CVAR, but have not actually raced yet.
I still need to get a physical and take their training school.
I've sort of inherited Gray Gregory's race car and it is stock bodied that I recently added fiberglass GTS flares.
That way I could use my old 15" wheels from my Pantera and get the wider tires under it.
Tom and I both use Avon slicks.
10.5/23-15 fronts
13/25-15 rears

Kirby
