Description

The Ksport Supercomp Big Brake Kit is engineered as an extreme brake upgrade, delivering superior stopping power for your 2011-2015 Kia Optima (Turbo and Non-Turbo models) without requiring vehicle modifications for installation. This sophisticated, bolt-on system significantly enhances braking performance, featuring larger calipers, rotors, and brake pads, along with an 8-piston caliper configuration for optimal force distribution. These calipers house aluminum pistons that offer superior heat resistance. The braking system utilizes two-piece, floating rotors, available in either drilled or slotted designs. Drilled rotors are recommended for daily driving due to better cooling, while slotted rotors are suggested for track use to manage heat and expel gases more effectively. Each kit is equipped with SC5 Street Brake Pads, providing a balance of performance for street and occasional track use, while significantly reducing brake dust and noise. D.O.T. compliant stainless steel braided brake lines are also standard, ensuring a firmer pedal feel and quicker response by eliminating line expansion under pressure. Standard kit components include two forged, monoblock aluminum calipers, two lightweight two-piece rotors (slotted or drilled), one set of SC5 Street Brake Pads, two stainless steel brake lines, and all necessary mounting hardware and brackets. Please note that Ksport Big Brake kits are built to order, and production and delivery typically require a 4-6 week lead time. The product is also subject to California Proposition 65 warnings regarding cancer and reproductive harm.
