Rear Brake Ducting

[Hardman69]

Twin ducts - long ones feed through a slot I cut into the rear dustshields, short ones feed towards calipers.

From Behind:

EBC "Charcoal stuff" pads, which I cooked before doing ducts:

I've got a series of "how-to" pics I took when I cut slots in the rear dustshields to duct air into the rear discs, Hassle Me if You want it posted (it's too late, I'm too tired).

noticeable difference?

noticeable difference?

Haha - ummm, yeah ! !

No more cooked pads, and no more super-heated rear discs. With no ducting, I got the rear discs so hot, they warped/bulged out between all the cooling-fins, brake-shuddering like nobody's business ! ! That was on a DAMP/WET track too!

Now it's all good, the rears don't seem to suffer as badly as the fronts (also with 2 ducts), which only last 3 flat-out laps at Winton (with R-Compounds on a 37deg day)
