135i/BMW Performance Caliper Install
It's been requested I make a thread covering my installation and such of the OEM 135i Brembo calipers I recently acquired. This also applies to the BMW Performance front and rear calipers. The BMWP brakes are the exact same, just Phoenix (or Austin) Yellow. A lot of this should also apply to the 996 Brembo caliper upgrades people have done.
I found a couple of threads, linked below, which have helped me, but none were really complete. I'm hoping this thread will serve as a more complete resource for anyone hoping to follow this route.

Front carrier brackets:
I bought mine from Reboot Engineering. These will allow for you to run standard E46 330 rotors (325x25).

Pads:
Pick the brake pads of your choosing, based on your driving objectives. I've been very happy with the Bosch QuietCast pads Peter installed on my car before I bought it, but for these I'm hoping for something that will be track-capable yet still low dust.
Front Rotors:
With the use of the Reboot carrier brackets, you may choose any standard 330 front rotor (dimensions are 325x25).
It's worth noting drilled rotors are purely for aesthetics.
Rear Rotors:
You will need to run standard E46 M3 rear brake rotors. The retaining screw hole will not line up, as it is different on the M3 and non-M. If you have studs, you're lucky and you suck. If not, it just makes reseating the wheel a touch trickier. A wheel hanger can be quite useful.
Brake lines:
RallyRoad extended brake lines are specifically manufactured for the Porsche (996) calipers on E46s (read: Brembo). Another company sells a kit for just the fronts on ECS, but they were back ordered for over a month and I'm impatient.
You need ~600mm fronts, and ~650mm rear lines. I tried emailing StopTech to see if they could help me pick lines by measurement, but weren't particularly helpful.

I will be backfilling information later. I'm on a conference call, and bored out of my skull, so I decided to go ahead and start typing away.
