I agree. As for looking at ugly drums, cars with factory styled wheels were supposed to have the face of the drum blacked out.Waste of time & $$$$. Not enough weight back there to really be worth it. I guess a lot have been done thinking it would improve stopping, but with the light rear and the way discs grab, you'll slide a lot more than stopping. IMHO!
I like the 10 X 2 1/2 drums Shelby used. My 64 has 68 fronts discs, rear std drums, and stops as quickly as I need. Can't see where rear discs would be better enough to spend what they cost!
