Girodisc Rear Caliper Rebuild Kit Porsche 981 Boxster S-Cayman S Track days can be especially hard on the piston seals and dust boots in your brake calipers. Heat, in particular, will do a number on them. (Titanium heat shields behind your pads can help with that.)  This kit is put together from the highest-quality components to rebuild a brake caliper back to like-new condition. One kit is required per caliper (we suggest doing them both as long as you're doing it).  Once you rebuild them, get the Ti heat shields as well and lengthen the interval between rebuilds.  The shields and seals are available as a kit for convenience (and a bit of savings). We only source superior quality brake components (brakes for track use are serious business); some kits don't take it as seriously.  Any questions give us a call, we're happy to help! Features: • Built for racing reliability and consistent performance • Compatible with demanding track environments • Designed for perfect fit and easy installation FAQs: Is this part track-proven? Yes, it has been tested extensively under racing conditions. Does it require professional installation? While not required, professional installation is recommended for best performance. Will this fit my vehicle? Please refer to the fitment guide or contact us to confirm compatibility. Can I return this if it doesn’t fit? Yes, as long as it’s unused and in original packaging.

A1-153 Girodisc 2pc Front Brake Rotors FITMENT: Porsche Boxster S and Cayman S (981), Front This Girodisc system is an upgrade from Porsche's 330mm one-piece OEM front rotors to 350mm two-piece floating steel rotors with aluminum hats, a direct replacement for the OEM brake disc. The two-piece floating disc will bolt directly to the car and work with your OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. Girodisc two-piece floating rotors are lighter than OEM brake rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response. When used with Pagid or PFC performance brake pads, and RF-1 brake fluid (available from ), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by Grade-12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance. Sold/priced per pair.

A1-266 Girodisc 2pc Front Brake Rotors for Porsche Cayman GT4 Clubsport FITMENT: Porsche Cayman GT4 Clubsport, Front This Girodisc system is a 380mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for the one-piece OEM Cayman GT4 Clubsport steel brakes. The Girodisc A1-266 will bolt directly to your Porsche GT4 Clubsport and will work perfectly with your OEM calipers.
