RX8 4-piston caliper STOCK SIZE Four Piston Brake Kit with TWO PIECE SLOTTED ROTORS

Machining: Slotted Surface: EDP Coating w/cross cut grinding on friction surface

4-Piston Caliper:

* Body machined from 6061-T6 forged aluminum. * Piston sizes are 38mm x 38mm.

* Double-sealed pistons with external fluid crossover.

* Saves almost half the weight of JDM 4 pistons.

* Powder coated red, resistant to heat and brake fluid.

Adapter: 7075-T6 Aluminum Alloy

Rotor Design: Our unique and patent pending rotor designs make our discs cooler and last longer. 1. Convergent vane design The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler.

2. Center-mount design The center-mount flanges for hat mounting to the rotor ring have several benefits.

* It allows the ring to be used on either side of the vehicle simply by mounting the hat on either side of the ring (unidirectional).

* The stress load transferred from the ring to the hat is balanced.

* Air inlets are widely open to both inboard and outboard sides of the rotor. More air suctions and even temperature on both sides of the disc surface.

* Heat transfer from the disc surfaces to the hat is even and minimized by increasing the flange length and the airflow around the flanges.

* Mounting flanges are on both friction surfaces ultimately provides excellent heat balance.

* Increases the offset from 12-15mm to eliminate the need for a wheel spacer.

3. True floating design Exclusive full floating design with 10.9 grade alloyed hardware. Hardware is DACRO coated and crimp locking. DACRO is highly corrosion resistant and provides a film for easier movement between the hat and rotor ring as disc expands and contracts and the crimp design provides positive engagement without rattling or torque loss at temperature.

These are dynamically balanced after slotting to ensure vibration-free use at high speed. The slots wipe away the white-hot boundary layer from the disc and pad to increase braking efficiency, particularly in wet conditions. The rotor is painted using an "electro-deposition" process for the very best in rust prevention. For version that fits our Enkei RP-F1 18x9.5, please email us.
