Years ago, the hot shaving setup from BFGs on camber
challenged cars was to shave the inside shoulders more
than the outers, 3-3-2 /32 across the tread surface,
or 3 -2 -3 /32 for cars that wore both shoulders out
(no camber and lots of toe out).
Of course this was in the days of full tread 226
gumball R1's that lasted 1-2 events.
