Brakes
Brake components for Porsche GT3 Cup and GT4 Clubsport race cars: calipers, master cylinders, brake-air ducting and spoilers, and related hardware, each verified against the factory part number.
Brakes are safety-critical. Every listing states its grade from our published 1–5 grading scale conservatively, and used brake components should be inspected by a qualified race shop before they go on a car — that expectation is stated on the listing, not buried. Factory numbers make cross-generation interchange checkable: many Cup brake numbers carry across 996/997/991 with revision suffixes, and we list what the catalog supports.
