Lotus Emira Rear Caliper Rebuild Kit Been to a few too many track days? If your rear calipers are feeling sticky or weak, this kit replaces the hard-worked piston seals and dust boots to get them operating like new. Fitment Lotus Emira rear caliper. If you are unsure about compatibility, compare your caliper’s piston count and dimensions to your factory service information. Refresh your rear braking performance with a precise, track-tested kit Each kit services one rear caliper and includes new piston seals and high-temperature dust boots built to our spec. Pair rebuilt calipers with titanium pad shields to reduce heat transfer and extend service intervals. CCRK2-388 Features One kit services one rear caliper Includes piston seals and dust boots made to our specifications Designed to withstand high brake temperatures common on track Restores caliper feel, consistency, and pad release Recommended with titanium pad shields for added heat protection What’s included Piston seals and dust boots sufficient to rebuild one Lotus Emira rear brake caliper. Fitment Lotus Emira rear caliper. If you are unsure about compatibility, compare your caliper’s piston count and dimensions to your factory service information. Installation notes Clean all components thoroughly; avoid scratching piston surfaces Use appropriate brake assembly lube and fresh DOT-rated brake fluid specified by the vehicle manufacturer After assembly, bleed the system and verify a firm, consistent pedal Follow torque specs and procedures in the factory service manual Lotus Emira Rear Caliper Rebuild Kit CCRK2-388 FAQs Does one kit cover both rear 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.

PFC Slotted disc 992GT3 Not for use in official Porsche Carrera Cup championships. PFC has released new V3 disc and hat technology. The advanced design features a patented attachment design that uses a retention ring that holds the hat and disc together. The ring means no need for torque wrenches, and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off, and making the vehicle lighter. This V3 disc retention method is based on the use of a two- or three-turn retaining ring, which is held in a groove in the hat that overlaps the disc flanges – effectively locking the disc to the hat. Reduced mass on disc connecting flanges, which reduces thermal distortion (more specifically, coning) at race temperatures. Reduced coning allows the pads to sit flatter on the disc, which better utilizes the available radial depth. There is better pad force distribution and the brakes will run cooler, reducing hot spots on the disc. This will also have the benefit of reduced taper wear of the pads. More heat will be contained in the brake faces because there is less of a heat sink in the flanges. This reduces thermal stress at the ID of the disc and reduces the chance of thermal cracking to occur. Consistent disc float from race beginning to end. As a race progresses with a bobbin disc, float will often be reduced when a bobbin is no longer sitting square in the disc. Reduced float will increase piston knockback, increase pedal travel and add vibration. Reduced complexity. The number of brake assembly parts is reduced from 38+ for a bobbin drive disc to just 3 in a V3 disc assembly Decreased assembly time. You can assemble a V3 race disc in a matter of seconds.
