Show original supplier description
The Ksport Dualcomp Big Brake Kit is an innovative rear brake solution engineered for Subaru Legacy models from 2000 to 2004. This kit addresses the need for enhanced braking performance and a functional integrated handbrake by utilizing a single 4-piston caliper. Within this caliper, two pistons are dedicated to the primary foot brake system, while the other two operate independently for the handbrake, ensuring separate hydraulic circuits for each function. The system is further enhanced by a polished titanium handbrake cylinder and lever, offering both aesthetic appeal and precise control. The kit comes standard with SC5 Street Pads, which provide optimal braking performance for street and occasional track use, minimizing brake dust, noise, and rotor wear with operating temperatures between 194°F and 1022°F. Additionally, D.O.T. compliant stainless steel braided brake lines replace stock rubber lines to prevent expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel. Customers can customize their kit by choosing between cross-drilled or slotted rotors; cross-drilled rotors are recommended for daily drivers due to cooler operation, while slotted rotors are suggested for track use. Caliper color options include standard finishes like Orange, Red, Black, and Yellow, with upgrades available for premium high-polish finishes and custom color options. This brake kit is Formula Drift legal and is built to order, with production and delivery typically taking 4-6 weeks. Fitment is confirmed for 2000-2004 Subaru Legacy GT models, and buyers are encouraged to use the search bar to verify compatibility with other specific vehicle configurations.
