A premium 4 piston caliper upgrade kit with 4 pads per caliper! 4 pads per caliper means twice the leading edges per pad. This also means the caliper has far greater control of the pads force distribution meaning a better feel through the brake pedal. Using either 332x28mm or 355x28mm two piece rotors this kit is also a SLIM version meaning a larger range of wheel choice. Overall, this is 16mm slimmer than the 4 piston / 4 pad kit and with the 332mm rotor, will fit most 17" wheels on todays market..

Rear caliper kit for drifting that controls the foot and parking brakes with one caliper.
The body of the SLIM FORGED SPORTS CALIPERS (4 Pistons × 4 Pads) has been improved for rear vehicle use. This product is a specialized brake caliper kit for drifting. The two opposing pistons on one end operate the foot brakes, and the two opposing pistons on the other end control the hydraulic parking brake. With regular in-drum parking brakes, there are limited choices for friction materials, and there are brake shoe durability problems resulting from the severe conditions created by drifting. With the handbrake cable, troubles such as wire stretching also occur after frequent use. By changing to this new braking system, such problems can be avoided. In addition, the friction materials for the foot and parking brakes can be changed to different materials, enabling the creation of a braking system that is more responsive to the driver. Repeated road testing has been carried out in Japan since 2006, and the product has earned high praise from top drift drivers in Japan, USA and Australia.
