SuperComp Big Brake Kit

The KSport SuperComp Big Brake Kit represents K-Sport's most extreme brake upgrade, engineered to deliver the highest level of stopping power for your 2005-2007 Subaru Impreza STI. This kit is designed as a direct, bolt-on replacement, requiring no modifications for installation. Constructed from a solid billet of aircraft-grade aluminum, the 1-piece calipers offer exceptional strength and light weight, while also being resistant to corrosion. The opposed-piston caliper design maximizes pad grip, reducing uneven wear and improving overall braking performance. Aluminum caliper pistons contribute to heat resistance and lighter weight, further enhancing braking dynamics. The kit includes reinforced carbon steel caliper brackets, allowing these larger-than-OEM calipers to mount directly to existing points. The SuperComp Big Brake Kit features 2-piece rotors with an aluminum center, which lowers rotational mass for quicker braking response and shorter stopping distances. This 2-piece design also minimizes rotor warpage by allowing for less restricted expansion and contraction of the outer iron section. The rotors are slotted and vented for optimal heat dissipation. The kit requires a minimum wheel diameter of 18 inches (457mm) and utilizes street pads.
