D2-242 Girodisc Rear Replacement Rotor Rings (Corvette C8)
$1,065.00
Fitment: Chevrolet Corvette C8 Z51
REPLACEMENT ROTOR DISCS ONLY. INCLUDES NEW INSTALLATION HARDWARE. DOES NOT INCLUDE ALUMINUM HAT.
Competition Motorsport is an authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. Â We ship most products same or next business day to ensure we meet your delivery deadline.
The Girodisc replacement rotor system is a direct rotor disc replacement for the Girodisc two-piece hat and rotor and no modifications are necessary. Â
The rotor and hat mount together through a floating mount system which utilizes 8-10 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 rotor only replacement to minimize replacement costs and deliver outstanding performance and cooling.
Sold/priced per pair.

Girodisc Front Caliper Rebuild Kit Porsche 981 Boxster S-Cayman S
$69.00
PORSCHE 981 BOXSTER S/CAYMAN S FRONT CALIPER REBUILD KIT
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.)Â 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!

Girodisc Titanium Brake Pad Shields for Corvette C7 Z07
from $128.00
The problem of brake fluid boiling is simply traced to heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible, of course, and the brake pedal goes to the floor instead of moving the caliper pistons.  Production cars tend to suffer from this on track days because they don't have the extensive cooling ducts and exotic brake materials found on racing cars. Â
Race-only brake calipers generally come with titanium caliper pistons for one reason: titanium has low thermal conductivity. This means it's very bad at transferring heat, which is good if you're trying to keep your brake fluid from boiling.  Here's a comparison of materials and their relative thermal conductivity ratings (lower is better):
Titanium 6AL-4V = 6.7 W/mk
Steel = 52 W/mk
Aluminum = 130 W/mk
Most fixed calipers use aluminum pistons which are, unfortunately, excellent at transferring braking heat to your brake fluid. Our solution is to place Girodisc's thin titanium shims between the brake pad and the caliper pistons. This helps prevent braking heat from transferring into the pistons and, thus, into the fluid.Â
For cars that are going to see hard or multiple track days, these shims are affordable protection from losing your brake pedal at the wrong time and making your track day very expensive.
Water jet cut to exact size; no cutting, grinding, or swearing involved.
Price is per axle (four shims)

The problem of brake fluid boiling is caused by braking heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible, of course, so brake pedal pressure compresses this air instead of pushing brake fluid and moving the caliper pistons. The brake pedal goes to the floor.
Production street cars tend to suffer from this on track days because they don't have the extensive cooling ducts and exotic brake materials found on race cars. Race-only brake calipers generally come with titanium caliper pistons for one reason: titanium has very low thermal conductivity, which means it's bad at transferring heat.
That's good if you're trying to keep your brake fluid from boiling. Here's a comparison of materials and their relative thermal conductivity ratings in Watts per meter-Kelvin (lower is better):
Titanium 6AL-4V = 6.7 W/mK
Steel = 52 W/mK
Aluminum = 130 W/mK
Most fixed calipers use aluminum pistons which are, unfortunately, excellent at transferring braking heat to your brake fluid. Our solution is to place Girodisc's thin titanium shims between each brake pad and the caliper pistons. This helps prevent braking heat from transferring into the pistons and, thus, into the fluid.
For cars that are going to see hard driving or multiple track days, these shims are affordable protection against losing your brake pedal at the worst possible time, making your track day very expensive.
