PORSCHE 911/992 TURBO S CERAMIC CERAMIC BRAKE SYSTEM BRAKE NEW
The Porsche 911 (992) Turbo S Carbon Ceramic Brake (PCCB) system represents a major generational leap over the previous 991.2. For the 992 platform, Porsche introduced a massive 10-piston front caliper architecture (manufactured by Akebono) to manage the increased power and weight of the new chassis.

Key Part Numbers (992 Generation)
When sourcing or listing these for Buy Mustang parts Ltd, ensure you differentiate them from the Carrera/GT3 parts ($410\text{mm}$), as the Turbo S $420\text{mm}$ setup is unique in its offset.

Fitment & Commercial Strategy
1. The 10-Piston Upgrade
The 992 Turbo S is the first 911 to utilize the 10-piston front caliper. This is the same hardware found on the Audi RS6 (C8) and Lamborghini Urus, but with Porsche-specific mounting.
-
Benefit: The massive pad surface area significantly reduces local heat concentration on the ceramic disc, extending its life during aggressive track use.
2. Wheel Clearance Requirements
-
Minimum Size: 20-inch wheels are required for the front.
-
Note: Because the $420\text{mm}$ rotor and 10-piston caliper fill the barrel almost completely, wheel weights must be placed carefully. Certain aftermarket 20-inch wheels with a “stepped” barrel may not clear the caliper face.
3. Unsprung Mass & Handling
-
Replacing a standard steel setup with these PCCBs saves approximately 18kg (40lbs) of unsprung weight. In a rear-engine car like the 911, this drastically improves high-speed damping and steering “flickability.”
Inventory Note for Buy Mustang parts Ltd
If you are listing a “New Take-off” or “New” set from a 992 Turbo S:
-
The “Black Caliper” Trend: Many 992 buyers now opt for the High-Gloss Black calipers (Option code 1LX) instead of the traditional Yellow. If you have a black set, highlight this in your listing as it is a highly desired “stealth” aesthetic for PCCB retrofits.
-
Visual Inspection: PCCB rotors should have a smooth, mirror-like finish. Any “graying” or rough texture (like sandpaper) indicates the carbon fibers have oxidized due to track heat, even if the rotor looks thick.
