Porsche Brembo 996 BBK conversion

[Slideways]

Would coding for CSL bias be different than ZCP?

Pretty sure they are the same as they both got the same braking hardware.

Hello Everyone,

I just purchased my e46 m3. The car came with this exact conversion. Can you all help me with the following questions? Thanks

1. Can anyone recommend some more aggressive pads for front and rear? Can you send me the direct link or part number? I feel the stock Porsche pads are kind of soft and don't stop really hard with aggressive driving.

2. I see conflicting answers to this question. Is this BBK conversion from a 996 Turbo and a Cayman S? I see some websites saying they sell the pads for with the part numbers but they say (except for Turbo models, or Except for Cayman S). If I was to go to a shop to rebuild the calipers, what car do I say these calipers and set they are from?

3. Are both the front and rear 4 pot?

Thanks for all your help

Welcome to the forum.

Right from the Rally Road site (most conversions are done using their kit):

Front:

Calipers used for this conversion are Front Calipers from the 1999-2004 Porsche 996 (non-turbo), the Boxster S or the Cayman S. All these calipers are made from the same Brembo casting.

The Porsche caliper part numbers for this conversion are:
996.351.425 (driver side)
996.351.426 (passenger side)

Rear:

Calipers used for this conversion are Rear Calipers from the 1999-2004 Porsche 996 (non-turbo), the Boxster S or the Cayman S. All these calipers are made from the same Brembo casting.

The Porsche caliper part numbers for this conversion are:

996.352.421 (driver side)

996.352.422 (passenger side)


Both front and rear are 4 pot.

I will leave the brake pad recommendations to others.

I installed the front 996 calipers on my 2004 convertible yesterday.

The process was mostly straightforward, but I encountered one major challenge: the 16mm carrier bolts. There was an excessive amount of Loctite on these bolts, so I had to use heat and PB Blaster to remove them. Even after applying heat and the blaster, it was extremely difficult to break them free.

This issue was frustrating and turned what should have been a one-hour job into a three-hour endeavor. If anyone faces a similar problem, I recommend removing the discs to gain better access to the carrier, which will help you apply heat more effectively.

I used Rally Road brackets (older style that I bought back in 2013) and did not have to grind anything to achieve a good fit.
