Before anyone starts bolting harnesses all over the place, I'm gonna
look up the 1996 SCCA CGRs tonight and report back with a definitive
answer tomorrow. I'm certain it specifies a maximum angle, just need
make sure what that is. Perhaps our cousins on the other side of the
pond can check the FIA specs (apparently their whole rulebook is now
IMHO aircraft requirements are completely different than auto-racing.
