Overview

The Ksport Slimline Big Brake Kit is a performance brake upgrade designed for aggressive-fitment wheels. This kit features a unique Slimline Caliper, engineered to match the thickness of OEM single-side piston calipers, allowing it to fit within the limited spacing of many factory or aftermarket wheels. It is designed for bolt-on replacement without modifications and includes stainless steel brake lines for faster pedal response.
Show original supplier description
The popularity of these wheels often means limited clearance between the caliper and the wheel's backside, a challenge addressed by Ksport's innovative Slimline Caliper design. This caliper maintains a profile similar to OEM single-side piston calipers, ensuring compatibility where traditional large multi-piston calipers might not fit. This kit features 350mm (13.8") slotted, vented, 2-piece rotors constructed from cast iron with a fixed hat. The 6-piston forged aluminum calipers, finished in orange, provide a larger brake pad surface area than OEM pads for improved braking performance. The 2-piece rotor design helps reduce warpage by allowing for more unrestricted expansion and contraction. Designed for a performance or racing driving style, the Ksport Slimline Big Brake Kit requires a minimum wheel diameter of 18 inches. The kit is specifically designed for the 2008-2014 Subaru Impreza WRX.
