| Re: Brake Ducting Fran During winter we may block ducts to maintain rotor temps but with Australian ambient temperatures ducts are a necessity.I've been racing without any ducts and got away with it until we went to South Australia's Mallala circuit where we ran 10 lap races with 30 degree ambient temps and tight hairpin corners after straights, I boiled fluid in rear brakes and cracked the rotors.Lesson is must have ducts.Always used them on the 240z too.I find once brakes are up to temp long straights only cool a little and temps certainly don't drop to pre race levels.I don't understand your final paragraph except for your drum brake line. My short answer is no thanks.
