    AP Racing introduced the J-Hook rotor to the general public in 2009 with the Nissan R35 GT-R. The release of the J-Hook pattern brought the benefits of a cross drilled and slotted rotor with none of the drawbacks. AP Racing has been using the J-Hook finish on the professional racing circuits for years and decided that it was time to bring this technology to the streets.

    There are many benefits to the patented J-Hook rotor design. The primary benefit is the increased durability and longevity. For years cross-drilled rotors have been recognized as the best rotor to provide excellent initial bite and additional grip on the pad. As the brake pad grabs the rotor the leading edges of the J-Hook create additional bite on the pad face and provide the driver with a much more positive feedback in braking performance.

    Additionally a drilled rotor can potentially form cracks from rapid expansion and contraction during hard use caused by dramatic changes in rotor temperatures. Because the J-Hook machining process does not penetrate through the rotor, it prevents the rotor from forming surface cracks and therefore, can withstand harder driving and high temperatures.

    Finally, the J-Hook finish retains all of the benefits of a traditional slotted rotor in that it cleans the pad surface and allows the pad to outgas through the recessed channels. Outgassing is when the temperature built up during the friction process cooks the gases out of the brake pad that could create a buffer between the pad and rotor which would be trapped in between the rotor and pad. By slotting the rotor face you are allowing the pad to releases these gases.

    The only potential drawback to a J-Hook rotor is that the passing of the J-Hook design through the pad can cause a light whirring sound that some customers might find to add character to the vehicle and braking system while some customers might find to be a bit distracting.

    The J-Hook design, perfected in top motorsports on race tracks, combines the excellent initial bite of a cross-drilled pattern with the longevity of a slotted pattern.

    J-Hook patterned rotors are immune to drilled rotors propensity to form spider cracks under high temperature during heavy use.
    Derived from AP Racing's patented and widely successful race Radi-CAL caliper and after 7 years of development, AP Racing has released their new pressure forged aluminum Radi-CAL caliper line validated for high performance road use and weekend track use. Using the latest FEA (finite element) analysis software and brake dynamometer testing, it was designed to implement the latest technologies learned through 40+ years of highly successful motorsports participation and an unparalleled 700+ F1 Grand Prix victories.

    AP Racing pressure forged aluminum caliper bodies are tested at over 500,000 cycles of pressure and torque to meet AP Racing's stringent OE and high performance road use validation testing to ensure maximum stiffness and durability required for use on road registered vehicles. The forged aluminum process was chosen as it offers a 20% stronger and lighter caliper than similarly sized units using a casting process. These larger, lightweight AP Racing calipers replace the typical heavy cast iron OE calipers that are designed for low cost and little regard to high performance driving.

    The opposed piston design guarantees maximum stiffness for better pedal feel and immediate braking action from the drivers input. Four piston and six piston designs allow a larger pad area to be used which decreases heat at the friction point between the pad material and disc surface while maintaining the same brake torque. This single detail increases both rotor and pad service life. Additionally, a larger caliper aids in braking performance by acting as a more efficient lever on the rotor. This in turn applies more torque to the rotor thus increasing the force applied to the rotor.

    By controlling the operating temperature caused by the friction between the pads and rotor we are able to better manage the performance of the big brake kit. Controlling the temperature in a braking system is one of the biggest goals when designing a kit. A vehicle will create the same amount of heat when stopped from the same speed, the brake component choices will control how that heat is managed. Both pads and rotors have optimum operational temperature ranges. For a street car, we must make sure the brakes work flawlessly at sub-zero temperatures but still offer excellent performance when being pushed on a race track and being subjected to extreme temperatures. All calipers are double sealed to protect piston bores and pressure seals from road debris. High temperature seal material is used to ensure safety at high temperature use. These seals are designed to minimize off brake pad drag on the disc which will increase pad and disc life.

    The Radi-CAL caliper is designed with differential piston sizing that minimize pad taper by equalizing piston pressure to the pad backing plate. The caliper pistons are hard anodized aluminum, lightweight and the most efficient material for insulating brake fluid from heat. An easily removable forged bridge support is implemented for quick pad changes without removing the caliper and adds additional strength to the caliper mouth for greater stiffness.

    Radi-CAL calipers are designed for larger, wider and taller annulus discs to increase thermal capacity, reduce disc surface temperatures and increase pad and disc life. Directionally loaded anti-rattle springs are featured to avoid pad knock or movement that is normally associated with race calipers. Radi-CAL calipers are hard anodized and then painted with high temperature paint for great looks and corrosion protection.

    CORE CHARGES
    Our exchange program is very simple and allows you to receive chrome plated wheels or powder coated calipers without unnecessary down time to your vehicle. We first send you a set of our high quality chrome plated GM wheels or powder coated calipers to have installed. The best way to purchase is with a credit card. We initially charge you for the Chrome Plating
    (wheels) or powder coating (calipers) plus a refundable core charge. 
    You must return your undamaged cores within ten (10) days, we then issue you a full core credit within ten (10) days of receiving the product. Cores returned late (after the 10-day period) will be charged a $30.00 (per day) late fee. There will be a $100.00 stripping fee on painted caliper cores. To insure the highest quality available we only exchange GM products and they must be for the same style and year. Any damages will be deducted from the core refund. You may contact WCC for return shipping assistance.
