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 stock 914-4 calipers are functionally identical. They change in how they mount, but the pad size and caliper piston size are the same. They all go over solid rotors, they all perform basically the same.

IMHO, cross-drilling solid rotors on a street car is a waste of time. On a track car, it's probably also a waste of time. On a track car with vented rotors (the thick ones with passages through the middle), it is worthwhile. Mostly because track cars get inspected thoroughly before and after every event, so the cracks that will eventually form can be caught early enough before the brakes fail catastrophically.
