This Girodisc conversion system is a direct rotor replacement for the Porsche GT4 Clubsport. These two-piece floating rotors will bolt directly to the car and work with OEM calipers perfectly.
By upgrading your brakes with lightweight high-performance Girodisc rotors (paired with Girodisc A2-176 rear rotors), your factory brake bias and ABS efficiency are maintained. The low rotational and unsprung weight allows for quicker acceleration and transient suspension response.
When used with Pagid or PFC racing brake pads and Thunderhill RF1 Racing brake fluid, you have an amazing, durable solution to cracked or broken carbon-ceramic rotors at a fraction of the cost of the factory PCCBs.
The hat of each rotor is machined from 6061-T6 aircraft aluminum. The disc is manufactured from cast iron using the same specs and materials as professional racing organizations. The curved-vane design acts as a centrifugal pump to force cool air through the disc.
The disc and hat mount together using a floating mount system with high-strength alloy steel drive pins and Grade 12 cap screws. The drive pins transfer braking load while maintaining axial and radial float between the disc and hat to accomodate heat expansion. Hardened washers and anti-noise springs eliminate the rattle and noise sometimes associated with floating rotors.
The two-piece Girodisc design allows for disc-only replacement (using Girodisc D1-176); the aluminum hats are re-usable to save money.
Sold/priced per pair.
