Overview

The Ksport Procomp 6 Piston Rear Big Brake Kit is a sophisticated, bolt-on brake upgrade designed for the 1995-1999 Subaru Legacy BD5. This kit enhances brake power, especially under sustained high-heat conditions.

Constructed with a one-piece billet aircraft-grade aluminum caliper for lightweight strength and corrosion resistance, it features aluminum pistons for better heat resistance.
Show original supplier description
The Ksport Procomp Big Brake Kit offers a significant upgrade in stopping performance for your vehicle. The kit includes a 6-piston ProComp caliper, finished in red, paired with a 380mm slotted rotor. The caliper is machined from aircraft-quality billet, weighing just over 5lbs, and features a differential bore configuration. Standard components include aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, all contributing to improved pad wear and caliper rigidity over OEM designs. The opposed piston caliper design enhances durability, while stainless steel brake lines prevent expansion under pressure.
