Overview

All components are made for bolt-on replacement without modifications. The calipers feature 1-piece construction from a solid billet of aircraft-grade aluminum for light weight and strength.
Show original supplier description
The calipers are constructed from a single piece of aircraft-grade aluminum billet, ensuring both light weight and unparalleled strength. They feature opposed-piston designs to improve pad grip and reduce uneven wear. The aluminum caliper pistons offer superior heat resistance and are corrosion-free. Reinforced carbon steel caliper brackets allow these larger-than-OEM calipers to mount directly to existing points. The kit includes 2-piece rotors with aluminum centers, which reduce rotational mass, leading to quicker braking response and shorter stopping distances. This 2-piece design also minimizes the chance of rotor warpage by allowing for less restricted expansion and contraction. Heavy-duty caliper seals are utilized for sustained high-temperature racetrack use, and stainless steel brake lines prevent expansion under high temperatures and pressures for faster pedal response. This kit requires a minimum wheel diameter of 381mm (15 inches). It is designed for the 2015-2018 Subaru WRX and is compatible with 2WD vehicles only. Note that the OEM handbrake may not function after installation.
