Description

This rear kit utilizes a single 4-piston caliper design where two pistons engage for the foot brake and the other two engage for the handbrake, each operating on its own hydraulic circuit. Constructed with performance and ease of installation in mind, the Dualcomp kit is a complete bolt-on package. It includes forged, monoblock aluminum calipers, lightweight two-piece rotors measuring 356mm in diameter and 32mm in width, and Ksport's SC5 street brake pads, which offer a balance of performance, reduced dust, and noise. The kit also comes with D.O.T. compliant stainless steel braided brake lines, known for improving pedal response and feel by preventing line expansion under pressure. Additionally, CNC-machined carbon steel caliper brackets ensure a direct fitment to the OEM caliper bracket locations. Customization options are available for the calipers, which come standard in colors like Orange, Red, Black, and Yellow. Premium finishes such as Silver, Gold, Titanium, and Glassy/Hard Anodized colors are offered, along with over 20,000 custom color choices for virtually limitless personalization. Rotor options include slotted or cross-drilled, with slotted recommended for track use and cross-drilled for daily drivers due to better cooling. This specific kit, model #BKSB030-445SO, is designed for the Subaru Impreza GC8 from 1993 to 1998, provided the vehicle has a 265mm OEM front rotor. Please note that Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks. The product is also subject to California Proposition 65 warnings regarding cancer and reproductive harm.
