Show original supplier description
This kit features robust 6-piston calipers, each crafted from a solid billet of aircraft-grade aluminum for exceptional strength, light weight, and corrosion resistance. The opposed-piston design enhances pad grip, promoting more even wear and superior braking force. The kit includes 380mm (15-inch) diameter, slotted, and vented 2-piece rotors. These rotors utilize cast iron braking surfaces and lightweight aluminum centers to reduce rotational mass, leading to quicker response times and shorter stopping distances. The 2-piece design also allows for greater expansion and contraction of the outer iron section, significantly reducing the risk of rotor warping under extreme conditions. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers mount directly onto existing factory points. The kit requires a minimum wheel diameter of 19 inches (482.6mm) to accommodate the larger caliper and rotor assembly.
