GiroDisc 1382 Front Racing Brake Pads  GP40 Sprint & GP10 Street/Track Compounds Dominate every lap with GiroDisc D1382 Racing Brake Pads, available in two elite compounds—GP40 for sprint racing and GP10 for street and track day use. Whether you're chasing podiums in HPDE or logging laps in long-distance formats, GiroDisc delivers the high-performance braking you demand. The GP40 Sprint compound provides aggressive initial bite and linear modulation, making it ideal for track day warriors, club racers, and time attack drivers. For street/track day drivers, the GP10 compound offers smoother torque, excellent pad life, and low rotor wear—perfect for sessions where consistency matters most. GiroDisc 1382 Product Highlights GP40 compound: High torque, linear bite for sprint racing, time trials, and HPDE GP10 compound: Long-wear endurance pad with low rotor wear and excellent pedal feel Consistent performance across wide temperature ranges for both compounds D1382 pad shape fits many high-performance brake calipers 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. These pads have been race-tested and hold up to the brutal conditions on the track.

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)

Girodisc A2-172 Rear Rotor FAQs: Why switch from carbon-ceramic to iron rotors? Iron rotors offer greater heat capacity, improved modulation, and dramatically reduced replacement cost—ideal for track-day or endurance use where carbon ceramics can degrade quickly. Are these a direct fit for the Z/28’s carbon-ceramic setup? Yes. They bolt directly to the factory hubs and work with the original Brembo calipers and parking-brake system. Do these affect ABS or stability control? No. Girodisc rotors maintain factory geometry and tone-ring compatibility, so all electronic systems function normally. What difference will I feel when driving? Expect smoother pedal feedback, improved heat management under repeated hard braking, and more consistent stopping power throughout a session. Upgrade your Camaro Z/28 with Girodisc’s rear iron rotor conversion and experience the durability, balance, and braking precision trusted by serious track drivers everywhere.

Chevrolet Camaro SS (5th Gen) Front Rotors Unlock the full braking potential of your 5th Gen Camaro SS with Girodisc’s two-piece floating front rotors—crafted to deliver lighter weight, improved cooling, and uncompromised OEM fitment. Designed for drivers who demand better response and durability without altering brake bias or ABS operation, these rotors are the ultimate upgrade for street and track performance. Race-Bred Engineering for Street Precision Each Girodisc rotor is precision-machined in the USA from proprietary high-carbon cast iron and paired with a 6061-T6 aircraft-grade aluminum hat. The floating mount system with anti-noise spring washers allows the rotor to expand and contract with heat cycles, eliminating rattle and ensuring smooth operation. The curved vane internal design actively pumps air through the rotor, enhancing cooling efficiency under extreme braking loads.
