Well, I run an autox car w/ 4wheel drums and Silicone, and haven't seen any
fade troubles (yet). Most local autocross courses are 30-90 seconds, and
that just isn't enough time to overcook the brakes -- in fact, Sunday I didn't
even get my tires up to optimum temperature, much less the brakes.
The arguments I've watched about drum vs. disc usually end up at a stand-off,
with discs having the stopping advantange and the drums having less weight
therefore less unsprung- and rotational-mass.
BTW, it isn't a british car, but earned honorary status after pushing a
quart of Valvoline out in 70 miles + 3 hot autoX laps. (For make of car,
just look at my machine name ;-] )
