That would be interesting to see, imo. Just what kind of improvement does one gain from converting to the rear disc set up?
Originally posted by Ducking_Fumbass What is nice about a drum is that the shoes are pulled off of the drum, reducing drag when the brakes are not applied.
This has been one thing that always bugged me about the front pad/rotor design. Even when not applying braking force, the pads still rest against the rotors. I'm sure that being completely removed from this surface would both improve off-braking cooling during spirited drives and therefore contribute to equipment longetivity.
Originally posted by Ducking_Fumbass I don't think that enough braking on a 2G is done in the rear to really cause concern for heat. This definately holds true once the fronts are upgraded.
Considering I have nearly 172k on my original drums back there, I would have to agree. Obviously, there is a certain aesthetic quality that is lacking in a rusty, piece of shit drum behind a shiny new wheel, but could the drums be manufufactured from a different material to both appear more pleasing to the eye? In any case, I'm sure a good 1/16" of surface oxidation hurts heat transfer on the sinks along the outer edge of the drum.

Agreed. I definitely think that rear discs provide more an appearance mod than much else, however I have heard numerous people state that having discs at all four corners helps with brake force modulation.
All in all, I think there's some good information in this thread so far. I've personally learned a thing or two, had a couple doubts eased, and a couple opinions confirmed. Good thread imo.
