AP Racing 372x34mm Replacement Ring AP Racing replacement 372x34mm J Hook rotor discs are used in many of the AP Racing brake kits. These replacement rotor ring measures 372mm x 34mm and features 72 directional cooling vanes. The AP Racing 13.05.10052 and 13.05.10053 rotor rings are directional, curved vane, heat treated and stress relieved. These are the exact AP Racing  rotor rings as CP7177-350GC and CP7177-351GC with the USA AP 13.05.10052 and 13.05.10053 part numbers. Same rings, different part part numbers.

Increased airflow and slower heat transfer to other brake components- AP Racing J Hook discs have a unique, high-count vane design that promotes airflow, heat evacuation, and rapid cooling. They don't rely on a large surface area to cool via radiation. The iron discs will move more air than your carbon ceramic's, and as a result they won't heat your brake pads, caliper pistons, and brake fluid up as quickly. You'll be able to run longer sessions without brake fade, and you'll enjoy the confidence that comes along with them. They'll also make any brake ducts that you have on the car more effective and useful. Huge range of compatible brake pad compounds- Iron discs will open up a much greater range of available brake pads. You'll be able to achieve a different feel, and tailor your brake setup depending on your needs and environment, whether that is running an AutoX or the most demanding racetrack in your area. You'll also likely be paying less per brake pad set than you were previously, and your pads will last longer. Inexpensive spare discs- You'll no longer have to spend thousands of dollars when it's time to replace your discs. AP Racing J Hook's typically only cost $400-600 per iron disc ring, so you won't have to stress about anything happening to them. They're inexpensive enough that you can always keep a spare set on hand, so you won't have to worry about any brake-related downtime when you're out at the track. Durability- Iron discs can take a beating. You can stash your spares in your race trailer, and you won't have to worry about handling them, covering them, dinging them, or chipping them when changing your wheels. As you can see, although iron discs do come with a slight weight penalty, they're still the smart choice if you run your car hard on the racetrack. They're the obvious solution that has been proven countless times on tracks around the world, at all levels of motorsport. Among iron disc choices, there are none better than AP Racing J Hooks. AP Racing J Hook Discs are the epitome of endurance racing components. They will hold up extremely well to any abuse you plan to throw at them. These discs have been proven time and again in professional racing, winning many races and championships (SRO, IMSA, WEC, Rolex, etc.). Two-piece Floating Design with Aluminum Hat As is the case with most metal, iron brake discs grow substantially when heated. As it is heated, a disc expands radially, increasing in diameter and circumference. One-piece disc designs run into problems when this occurs. Look at the picture below and imagine the disc is being heated on the track. As the disc expands, the outer edges of the disc are pulling away from the center of the disc, but there are no built-in provisions to allow for that expansion. The edges of the disc therefore pull, lift, and distort, which is called coning. Now imagine that disc vertical on the car, running in your caliper. Coning directly impacts the brake pads’ contact with the disc, leading to uneven wear and tapering, and even a long brake pedal. Two-piece discs on the other hand, compensate for the expansion of the disc as it heats. This is accomplished by building ‘float’ into either the disc itself, or the disc hat/bell. In this case, the float is in the disc. If you look closely at the picture below, you can see that the mounting holes for the hat attachment bobbins are not round. They are an oblong shape. These channels allow the hat mounting hardware to slide as the disc is heated and expands, allowing the disc to run true in the caliper without distortion. That means less distortion, stress cracks, and pad taper.

We ship most products same or next business day to ensure we meet your delivery deadline. Fits Corvette C8 The GiroDisc system is a direct replacement for the OEM brake disc. The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and Discovery Parts RF-1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron which is constructed in the USA and is 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 8-10 high strength alloy steel drive pins manufactured by GiroDisc in the USA to our 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 grade12 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 2-piece GiroDisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.

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 A1-145 Girodisc system is a two-piece steel rotor and aluminum hat combination that directly replaces the fragile and expensive front ceramic brake discs on the C7 Z07. A different brake pad with an annulus -- pad swept area -- of 66mm or less must be used. This is done to keep the rotor weight as low as possible. We recommend using the Cobalt C7 Z07 racing brake pads with this system. Upgrading your brakes with these lightweight, high-performance replacements is an excellent solution to the expensive, fragile ceramic rotors on the C7 Corvette Z06 w/Z07 package. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum.

The rotor and hat mount together through a floating mount system of high strength alloy steel drive pins, manufactured by Girodisc in the US to their own specifications and cadmium plated for corrosion resistance.

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.

We recommend using the Raybestos ST43 or Pagid 2487 racing brake pads with these Girodisc rotors.
