Stock rear brake questions Options

[HalfMoon]

So which calipers (or the stock variety) are better? Late or early (and why)? Or does it not make much difference?
Also, and this may sound like an odd question....is there any reason why the rotors couldn't be drilled while on the car (other than the labor involved) and yes I have no plate.
Thanx

The rear rotors are solid, like stock 914-4 front rotors. So no--no positive effect. Same reasons as I gave above. Additionally, the rears do much less work than the fronts do, so they build less heat in the first place.

The 914-4 rear calipers are all interchangeable, I think the only actual difference is that some have one bleeder (put it at the top!!) and some have two, one at the top and one at the bottom.

Awesome stuff Dave and thanks!
My plan is to keep em and git the PMB rebuild kit as I'm assuming (from all I've read) that they most likely aren't working (or barely) and are sorely in need of a rebuild.
911's on front and probably in need of a rebuild as well (although, in a different thread we've been talking about the possibility of 928 brakes for 3.5 spacing-must check mine tomorrow-doubtful they are)
