3-Piston Caliper Brake Kit

The Ksport Slimline 3-Piston 330mm Front Big Brake Kit (BKSB091-332CO) is engineered to provide enhanced braking performance while accommodating aggressive wheel fitments and limited caliper clearance. Developed with the popularity of such wheels in mind, this kit utilizes a Slimline caliper design, inspired by OEM single-side piston caliper thickness, to maintain a profile that often fits where traditional multi-piston kits cannot. This ensures you can upgrade to a Big Brake Kit and still fit most factory or aftermarket wheels with very limited brake caliper clearance. This front big brake kit includes 3-piston calipers, which offer a significant upgrade over stock. The kit comes standard with SC5 Street Pads, designed for optimal braking in street and occasional track conditions, reducing dust by over 50% and minimizing noise and rotor wear. D.O.T. compliant stainless steel braided brake lines are also included, which prevent line expansion under pressure, leading to quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport offers customization options for this kit. You can choose between cross-drilled or slotted rotors, with cross-drilled recommended for daily drivers due to cooler running temperatures, and slotted recommended for track use. The caliper brackets are CNC machined from carbon steel to allow for a direct bolt-on installation to OEM caliper bracket locations. Calipers are available in standard painted colors like Orange, Red, Black, and Yellow, with options to upgrade to premium finishes. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This specific kit is listed as fitting the Subaru Legacy from 2003-2009.
