Rear 4 Piston Big Brake Kit

The Ksport Rear 4 Piston Big Brake Kit is engineered to provide superior stopping performance and reduce brake fade for your vehicle. This comprehensive kit includes a pair of 8-piston calipers, precision-machined from aircraft-quality billet aluminum into a lightweight, one-piece construction. These opposed-piston calipers offer improved pad grip and rigidity compared to OEM designs, while aluminum pistons resist corrosion and reduce weight. Each kit features 2-piece, 15-inch (380mm) slotted rotors with a 32mm width. The floating disc option is available to mitigate thermal stresses from extreme heat, preventing rotor warping and maintaining a flat braking surface. The unique rotor slot design efficiently expels heat, dust, and gases, while Ksport's calipers utilize heavy-duty seals for sustained high-temperature use. For enhanced pedal response, the kit includes stainless steel brake lines that resist expansion under pressure. Ksport offers various rotor styles, including slotted (recommended for track use) and cross-drilled (recommended for daily driving). Buyers can also choose between SC5 Street pads for everyday use or RC1 Race Pads for extreme track conditions. The kit is backed by a standard 12-month warranty covering manufacturer defects.
