Girodisc A1-268 Front Rotors for Toyota GR Corolla & GR Yaris
$1,050.00
Girodisc A1-268 Front Rotors for Toyota GR Corolla & GR Yaris
FITMENT:
Toyota GR Corolla (2023+), front
Toyota GR Yaris (2020+), front
This Girodisc two-piece rotor set is a direct replacement for the front rotors on the Toyota Corolla GR. Girodisc two-piece, fully floating rotor assemblies help shed unsprung weight and rotating mass from the front axle of the Toyota Corolla GR, while being far more durable in track use.
American Made With Specially Formulated Materials
Girodisc rotor rings are machined from a proprietary casting made of high-carbon steel formulated to Girodisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 72 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The two-piece design means the reusable hat which can be attached to new rotor rings (part number D1-268) when the latter need to be replaced.
All major components including the hats, rotor rings, and drive pins are manufactured in-house at the Girodisc facility in Bellingham, WA, from domestically-sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodized finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware.
We also recommend replacing them if a crack leads to the edge of the ring.
Sold and priced per pair.

GiroDisc 1382 Frequently Asked Questions (FAQ)
What’s the difference between the GP40 and GP10 compounds?
The GP40 is a high-bite sprint racing pad for aggressive braking and short sessions. The GP10 is a smoother, longer-wearing compound ideal for street and track day use.
Can I daily drive with GP40 or GP10 pads?
GP10 is the best compromise between street and track use. GP40 compound pads are engineered for track-only use. They may be noisy, dusty, and lack the cold bite necessary for street driving.
Do both compounds fit the same D1382 shape?
Yes. Both GP40 and GP10 are available in the D1382 pad shape, compatible with various performance calipers.
What type of racing is GP40 best for?
The GP40 compound excels in endurance formats such as 6-, 12-, or 24-hour races where consistency and wear resistance are key.
Do I need GiroDisc rotors to use these pads?
No, but pairing these pads with GiroDisc two-piece rotors is recommended for the best results.
GP10-1382.17 Brake Pads
GP10 compound is a high-performance street pad which is designed to have a smooth bite and make minimal noise at cold temperatures. Made for us by a friction technology specialist in Japan, it can be taken on track if you truly need a pad that does it all.
Please note that if your car spends more time on track than the street, we would recommend stepping up to a full race pad like our GP40.
GP40-1382.17 Brake Pads
GP40 compound falls between a sprint and an endurance compound. It maintains good bite and pedal feel while being friendly to your rotors. They are a favorite among our track day customers and shares a lineage with compounds found on cars competing in legendary races like the 24 Hours of Le Mans.

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.) 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!

The Endurance compound is the longest-lasting pad on the market right now, currently dominating the paddock at Le Mans and most other endurance events. The Sprint compound sacrifices approximately 30% in longevity for an increase of about 30% in bite. Which compound is right for you depends on what you’re trying to get out of your 600LT or 720S. It's worth mentioning that the Sprint compound still lasts longer than most endurance compounds offered by other racing brake manufacturers.

Girodisc Titanium Brake Pad Shields for Corvette C7 / C8 Z07

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.
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.
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.

Lotus Emira Front Caliper Rebuild Kit CCRK2-388 FAQs
Does one kit cover both front calipers?
No. One kit services one caliper. Order two kits to service both rear calipers.
How do I know my caliper seals need replacement?
Common signs include uneven pad wear, dragging brakes, fluid seepage, a soft pedal, or pistons that don’t retract smoothly after braking.
Can I install this at home?
Experienced DIYers can rebuild calipers with the right tools and a service manual. If you are unsure, consult a professional technician.
Do I need new brake fluid after the rebuild?
Yes. Always use fresh fluid that meets the manufacturer’s specification and fully bleed the system after service.
Will titanium pad shields really help?
They reduce heat transfer from pads to pistons, helping protect seals and fluid, especially during repeated high-temperature track use.
Ready to restore consistent braking performance? Add the Lotus Emira Rear Caliper Rebuild Kit to your cart, and consider titanium pad shields to keep your system cooler on track.
