Brake upgrade to 2007 GT3 PCCB specifications:

Calipers Front 380mm: 997.351.431.92 (L) 997.351.432.92 (R)
Calipers Rear 350mm: 997.352.425.98 (L) 997.352.426.98 (R)

Disc Front 380mm: Brembo steel rotors.
Disc Rear 350mm: Brembo steel rotors.
Aluminum Brembo hats for GT3.

Adapter needed for steering spindle on front brakes: 130mm spindle to 225mm caliper mounting holes.

Porsche adapter 997.351.505.04 is for a 142mm spindle to 225mm caliper mounting holes. This adapter is for a 997 C4 or Turbo upgrade to the larger 225mm six-piston calipers.

No adapters needed for the rear brakes.

Has anyone completed this PCCB upgrade on a 996.1 C2?
Will the above adapter work? Adapter specifications are not available in PET.
What are the disc or rotor hats required for the PCCB front caliper off set?
Is a larger master cylinder required for the six piston front and larger four piston rear calipers?

Thank you for your expert 996 advice.

Actually interested in this upgrade as well, hope to hear from someone that has done it or knows about it.

996.1 C2 will require different knuckles/spindles.

This.

C2/C4 - Same Suspension Design. Same Brake Design. Most Components Swappable between these models.

C4S/Turbo/GT2/GT3 - Same Suspension Design. Same Brake Design. Most Components Swappable between these models.

Just to knit pick, the c2 suspension is slightly different than the c4 as is the carrier/spindle.

We have a CCM brake package using Corvette ZR1 discs with RB 6/4 pot calipers for those cars equipped with 130mm mounting spread in both front & rear spindles.

Rotors will have the same build as those just released for 991 GT3, but the adapters will be made specific for different spindles and offset.

Due to the variety of retrofitting combination from end-user in caliper, rotor and spindle/upright etc, we have decided to sell only the whole package to assure the fitment and system integrity, and will not sell just the adapter (bracket) in order to avoid compatibility issue and trouble.

Racing Brake just posted additional information.
