GIRODISC A1-154 Front Brake Disc Kit for PORSCHE 991 GT3 / GT3RS / GT2RS / Cayman GT4 / GT4RS (410x36mm, PCCB Replacement)

The GIRODISC A1-154 front disc kit is a direct replacement for PCCB systems on Porsche models, allowing the use of pads compatible with original GT3 iron discs. The reduced annulus provides lower rotor mass, optimal pad selection, and improved track performance without unnecessary weight penalty.

The two-piece design consists of a 6061-T6 aircraft-grade aluminum center hat and a proprietary cast iron disc. The curved vane ventilation structure enhances airflow and cooling. The floating mount utilizes 12 cadmium-plated steel studs, Grade 12.9 hardware, and anti-vibration shims to reduce noise and allow for thermal expansion without distortion.
