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. There are two main reasons for replacing your OEM rotors: first, the Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the slotted Girodisc A1-266 will far outlast the OEM drilled rotors. When subjected to intense heat in a racing or track-day environment, the drilled holes in the OEM rotors form cracks which can lead to rotor failure. When paired with the Girodisc A2-266 rear rotors, your factory brake bias and ABS efficiency are maintained. When used with Pagid or PFC performance brake pads and CMS RF-1 brake fluid (available from ), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of each Girodisc 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 class 12.9 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. 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.

Girodisc Front 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!

We ship most products same or next business day to ensure we meet your delivery deadline. The Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake rotors. These two-piece floating rotors 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 brake bias is maintained, along with your ABS efficiency. Each Girodisc two-piece floating rotor is approx. 1.6 lbs. lighter than the stock units, 22.0 lbs. vs. 23.6 lbs. 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.

A1-211 Girodisc 2pc Front Brake Rotors for Camaro ZL1 (Gen 6) FITMENT: Chevy Camaro ZL1 (Gen 6), Front The Girodisc system is a direct replacement for the OE disc, but a different brake pad with an annulus (pad swept area) of 66mm or less must be used. We strongly recommend the Pagid 8081. This reduction in rotor annulus is done to keep the weight of the rotors low. The OEM rotors utilize a pillar vane design which is horribly inefficient in terms of dissipating heat. Since the OEM rotors heat-soak very easily, Chevrolet chose an easy solution to this problem: increasing the rotors' mass to combat that heat. We weighed an OEM rotor at 32.5 lbs. -- holy smoke! Girodisc took the functional route instead, engineering a shorter-annulus rotor ring for a total rotor-and-hat weight of 28.0 lbs. This design utilizes 72 directional cooling vanes for an incredibly efficient and robust package. The necessary pad shape is very common, found on other Camaro and Corvette applications equipped with six-piston calipers. If there's a specific pad compound you're after please contact us at 888 748 7223 and we'll get you what you need!

A2-211 Girodisc 2pc Rear Brake Rotors (ZL1 Gen 6) is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most Girodisc products the same or next business day to ensure we meet your delivery deadline. Fits Chevrolet Camaro ZL1 Gen 6 These Girodisc iron rotors are a direct replacement for the OE brake discs with no modifications. The central hat section of the Girodisc rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved-vane design, developed in racing to act as a centrifugal pump forcing cool air through the disc. The disc and hat have a floating mount system, which utilizes 12 high-strength alloy steel drive pins, manufactured in the US by Girodisc and cadmium plated for long-lasting corrosion resistance. These pins take the loads from braking while maintaining the axial and radial float between the hat and disc. They are secured by class 12.9 cap screws and hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs on the disc side, allowing the iron disc to expand as it heats up while eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the brake pads. Once the Girodisc system is in place, you simply replace the cast iron discs when needed. This reduces cost over time by allowing you to re-use the aluminum central hats.
