The opposed-piston caliper design greatly improves pad grip and reduces uneven wear, while aluminum pistons offer better heat resistance and smoother operation.
Show original supplier description
The Ksport SuperComp Big Brake Kit represents K-Sport's most extreme offering for vehicles requiring exceptional stopping power. This kit is engineered with larger-diameter disc rotors and an opposed-piston caliper design to significantly enhance pad grip and minimize uneven wear. The calipers themselves are constructed from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant foundation. This 1-piece construction contributes to the kit's overall durability and performance. Key features of this SuperComp kit include 8-piston calipers paired with 356mm (14-inch) drilled, 2-piece vented rotors. The rotors utilize an aluminum center to reduce rotational mass, leading to quicker braking response and shorter stopping distances. The 2-piece design also allows for less restricted expansion and contraction of the outer iron section, greatly reducing the chance of rotor warpage. All caliper seals are heavy-duty for sustained high-temperature racetrack use, and the included stainless steel brake lines prevent expansion under high temperatures and pressures for faster pedal response. Reinforced carbon steel caliper brackets allow these larger-than-OEM size calipers to bolt directly onto existing mounting points. This kit requires a minimum wheel diameter of 457mm (18 inches) and is specifically designed for performance and racing driving styles. The street-ready pad type ensures versatility for both track and street use.
