GiroDisc 4008 Racing Brake Pads – GP40 Sprint & GP10 Street/Track Compounds Dominate every lap with GiroDisc D4008 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 4008 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 4008 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 D4008 shape? Yes. Both GP40 and GP10 are available in the D4008 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. GiroDisc GP10-4008.17 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. GiroDisc GP40-4008.17 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.

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!

Girodisc McLaren 600LT / 720S Brake Pads (Front) These all-new Girodisc brake pads are designed specifically for use with the Girodisc A1-206 rotor conversion kit for the McLaren 600LT and 720S. These specially-designed pads are available in two excellent breakthrough compounds: Endurance and Sprint. 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 McLaren 600LT & 720S Brake Pads (Rear) These all-new Girodisc brake pads are designed specifically for use with the Girodisc rotor conversion kit for the McLaren 600LT and 720S. These specially-designed rear pads are available in a single compound that has been optimized to provide unsurpassed performance with either the Endurance and Sprint compounds available on the Girodisc front pads.

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 Titanium Brake Pad Shields FITMENTS: Porsche 991, 992, GT4 (Front) 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.

GiroDisc "Magic Pads" are the solution to your squeaky, dusty, expensive factory replacement pads. They have lower dust than typical factory pads and much less than other performance pads. You won't be cleaning your wheels nearly as often! Additionally, they have great initial bite, something most less-expensive pads lack. But the real reason people like Magic Pads so much is they are the "silver bullet" to brake noise problems. Magic Pads are a semi-metallic composition that is easy on rotors and on your wallet. We recommend always replacing pads as a whole car set when switching compounds. All Magic Pads come with anti-noise shields pre-installed and included in the price. If you have any questions, give us a call at (844) 438-7244. We're happy to help!
