Show original supplier description
The Ksport Supercomp Big Brake Kit represents an extreme upgrade for your Subaru Forester (2003-2007), engineered to deliver superior stopping power without requiring modifications to your vehicle's original setup. This sophisticated, bolt-on system enhances the performance of your existing Procomp kit with larger calipers, rotors, and brake pads, along with an increased number of pistons and standard full-floating rotors for improved self-centering. Constructed from a solid billet of aerospace-quality aluminum, the one-piece caliper design ensures lightweight strength and corrosion resistance, while aluminum pistons offer better heat management. Its two-piece floating rotor design allows for slight adjustments, reducing brake drag and improving performance through more even application. The included SC5 Street Pads provide optimal braking for street and occasional track use, reducing dust and noise while maintaining effective performance across a wide temperature range (194°F - 1022°F). D.O.T. compliant stainless-steel braided brake lines are standard, offering a quicker pedal response and firmer pedal feel by preventing expansion under pressure. This specific kit features 356mm (14-inch) diameter, 32mm width, slotted rotors, recommended for vehicles that see more track use. Custom caliper color options are available, including standard painted colors like Orange, Red, Black, and Yellow, with premium high polish finishes and over 20,000 custom color finishes also being offered. Standard kit inclusions are (2) Forged Monoblock Aluminum Calipers, (2) Lightweight Two-Piece Rotors (Slotted or Drilled), (1) Set of SC5 Street Brake Pads, (2) Stainless Steel Brake Lines, and all necessary mounting components and hardware. Ksport Big Brake kits are built to order, so please allow 4-6 weeks for production and delivery.
