What This Product Does

The discs provide the rear friction surfaces required to convert vehicle movement into heat during braking. Their carbon-fibre and silicon-carbide construction is designed to manage repeated heat cycles while reducing rotating and unsprung mass compared with conventional cast-iron discs. The floating arrangement allows controlled expansion between the rotor and centre bell.

Functions

• Provides compatible rear braking surfaces for the specified Porsche 992.2 applications
• Manages heat generated during repeated braking
• Reduces unsprung and rotating mass
• Allows controlled thermal expansion through a two-piece floating design
• Produces less brake dust than a conventional cast-iron disc and matching pad combination

Technical Details

• Rear disc size: 390 x 32mm
• Manufacturer-listed weight: 6.4kg
• Two-piece floating carbon-ceramic construction
• Carbon-fibre long-strand material reinforced with silicon carbide
• CNC-machined 7075-T6 billet centre bells with a hard-anodised finish
• Designed as a direct-fit replacement for compatible PCCB M450 or steel rear discs

Symptoms of Fault

• Cracks, chips or other visible rotor damage
• Brake judder or vibration during deceleration
• Uneven braking response or abnormal pad wear
• Disc measurements at or beyond the specified wear limit
• Warning messages or braking behaviour requiring specialist diagnosis

Why Replacement Matters

Damaged or worn brake discs can affect pad contact, braking consistency and pedal response. Replacement should follow inspection of both rear discs, the compatible brake pads, calipers, sensors and associated fitting hardware. Ninemeister develops Porsche-focused components using specialist experience with road and track-oriented braking systems.

FAQs

• Can these replace Porsche PCCB discs? They are designed as a direct-fit rear replacement for compatible Porsche Ceramic Composite Brake systems with option code M450.
• Can they replace steel brake discs? The manufacturer also identifies them as a direct replacement for compatible steel-disc configurations. Confirm the vehicle's original brake specification before fitting.
• Are brake pads included? Kit contents beyond the rear discs are not specified. Confirm the required compatible pads and fitting components separately.
• Is specialist installation recommended? Brake-system work should be completed by a suitably qualified technician, followed by the correct inspection and bedding procedure.
