1993-1998 STI ProComp 4 Piston Rear Big Brake System by Ksport

These brake systems are designed for easy installation with minimal tools required (in most applications). Their extreme lightweight caliper comes in differential bore configuration. It is machined from aircraft quality billet, weighs just over 5lbs. each, and has machined in protection grooves for the bridge tubes. Aluminum pistons, high temperature seals, and stainless steel brake pad wear plates are also standard on each caliper design. The opposed piston caliper design greatly improves pad wear and caliper rigidity over the OEM design. The stainless steel brake lines stop expansion under pressure. Most applications utilize the 2-piece floating disc assembly, which reduces weight both rotating and unsprung. The floating disc
