Porsche 996 Brembo BBK Conversion Install

[duracellttu]

Thanks. Edited to reflect this information.

Calipers used for this conversion are calipers from:

• 1998-2005 Porsche 996 (C2/C4, non-turbo)
• 1999-2004 Porsche 986 Boxster S
• 2005-2012 Porsche 987 Cayman S

I have collected a bunch of information and part numbers for everything you need to rebuild these calipers and install them. This was put together during my build, where the old forum had lots of out-dated information across may threads. See the attached PDF. Hope it helps members in the future.

Still learning this forum and search function. My StopTech Trophy kit just got cancelled because StopTech is closed down. I am debating going the 996 caliper route for some time.

Does anyone know the brake bias numbers for the following options?:

MK20 ABS system
- 996 caliper front, non ZCP M3 caliper rear
- 996 caliper front, ZCP M3 caliper rear
- 996 caliper front and rear

I believe someone reposted the tables for mk20 and mk60 here, I just don't remember the thread name.

Buildjournal has some pretty good info on this here: https://thebuildjournal.com/tech-gui...-chart-e46-m3/

what are your thoughts on ECS's rotors? besides the fact they look sweet af. They are priced way higher than the OEM CSL/ZCP's.

I havent driven the car much since were on quarantine so I cannot give a full assessment. From the very little driving i have done - Braking performance seem to be a little bit better, not by much however. I seem to get better acceleration - could be attributed to the weight savings - Im not sure if this is placebo effect but the car feels more nimble if that makes sense.

All my rotors were due for replacement so I was able to justify spending extra on the fronts for the ECS rotors. If you go through a few rotors, I suggest going FCP Euro route for the free replacement. Cant beat that. But If you are like me - I put about 7500 miles on the car last year as my DD, Im ok spending a little bit more on the ECS rotors - knowing that this rotor will probably last me for a while. I dont track but I like to do 5-6 mountain runs throughout the year - I saved some Pagid Pads for that. Ceramic pads dont grip anywhere near as well but they are great for maintenance.

Thanks for making this thread. On the brake lines, between RallyRoad and CreationsMotorsport (which seem to be made by HEL), which is better in terms of quality/fitment?

Stick with RR. There have been a few reports of issues with CM.

Good to know, thanks.

I agree - stick with RR. Just get the brackets and lines at the same time. Quality parts plus fast shipping.
