Show original supplier description
The Ksport Slimline 3-Piston Big Brake Kit offers a significant braking performance upgrade for 2000-2004 Subaru Legacy models, specifically designed to accommodate aggressive wheel fitments and factory wheels with limited caliper clearance. Its innovative Slimline caliper design mimics OEM thickness while providing the stopping power of a multi-piston system. This kit features lightweight two-piece 350mm rotors, available in slotted or cross-drilled options. Slotted rotors are recommended for track use, while cross-drilled rotors are recommended for daily drivers due to their cooler running temperatures. The calipers themselves are available in standard colors like orange, red, black, and yellow, with options for premium finishes including silver, gold, titanium, and various anodized colors, offering extensive customization. Included with the kit are Ksport's SC5 Street Pads, engineered for optimal braking performance in street and occasional track conditions, offering reduced dust and noise compared to race pads. The system is complemented by D.O.T. compliant stainless steel braided brake lines, which prevent expansion under pressure, leading to a quicker pedal response and a firmer pedal feel. CNC machined carbon steel caliper brackets ensure a direct bolt-on installation to the OEM caliper bracket location. Ksport Big Brake kits are built to order, with a production and delivery time of 4-6 weeks. Fitment should be confirmed for your specific vehicle, as Ksport offers a comprehensive fitment list and encourages users to verify compatibility.
