Rear Disk or Drums

From a braking perspective, the rears only provide about ~30% of your braking, depending on your car's weight balance, tire sizes, etc.

But, that doesn't mean that disks don't have advantages. They don't stop working if they get wet like drums do. They also dissipate heat better, and weigh less. I find the application feel is more consistent too, drums seem to lock up easier when pushed hard. And then of course there's the adjustment, even with the self-adjusters the drums aren't always set the way they should be. When I back out of my driveway I almost always turn one direction, so, guess how often one rear drum locks up before the other? A little entertaining.

That said, I still run 11x2.5" drums on all of mine. One of these days I'll start converting them all over to disks, but it's not the first thing on my list.

Also, I wouldn't pay $350 for drum brakes. I've purchased from this seller before, top notch. 11x2.5's for $100, minus the drums.
