Rich,
Maybe you just used the brakes too much? (:-)=F0=9F=98=80
Okay, so the SCCA cars were a bit lighter than stock, the vintage
prepared 2000 not quite as light, but still lighter than stock. At the
SCCA Driver's school I took at Nelson Ledges in NE Ohio, we were
instructed; "Throttle good, brakes bad!". Nelson is/was a 2.1 mile 13 turn
track. Brake at 4, 6, 12, & 13. And yeah, after 20 hard laps, there was
some brake fade, but nothing to worry about.
