Description

The Ksport Slimline Big Brake Kit offers a significant upgrade for the 2015-2018 Subaru WRX, specifically engineered to address the clearance challenges posed by aggressive wheel fitments. Traditional big brake kits often struggle to fit within the tight confines between the caliper and the back of the wheel, but Ksport's Slimline Caliper design maintains a thickness comparable to OEM calipers, ensuring compatibility with most factory wheels or those with very limited brake caliper clearance. This makes it an ideal solution for enthusiasts seeking enhanced braking performance without compromising wheel selection. This kit includes a forged aluminum 6-piston caliper, providing a larger brake pad surface area for improved stopping power over stock. The braking system is further enhanced by 2-piece slotted and vented rotors, constructed with cast iron and featuring an aluminum center. This design contributes to lower rotational mass, quicker response times, and shorter stopping distances. The 2-piece rotor construction also significantly reduces the risk of warping by allowing for more unrestricted expansion and contraction of the iron braking surface. Included components feature stainless steel brake lines, which resist expansion under high temperatures and pressures, leading to a firmer and more responsive pedal feel. The components are geared towards performance and racing driving styles, aiming to improve braking performance and durability under demanding conditions. The kit includes all necessary mounting hardware, brackets, and bolts for installation. Application is specific to the 2015 - 2018 Subaru WRX models.
