4 Piston Rear Caliper Kit with Stainless Steel Lines

The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring lightweight strength and superior corrosion resistance. Inside, aluminum pistons provide excellent heat management and consistent operation. Specifically for rear applications, this kit utilizes lightweight 4-piston aluminum calipers, a design that markedly improves pad wear and caliper rigidity compared to stock components. The kit incorporates CNC-machined carbon steel caliper brackets that facilitate a direct bolt-on fit to the OEM caliper bracket locations. Additionally, D.O.T. compliant stainless-steel braided brake lines are included, which resist expansion under pressure, leading to quicker pedal response and a firmer pedal feel. Included with the kit are NAOC Ceramic SC5 Street Pads, optimized for street driving and occasional track use. These pads offer a significant reduction in brake dust (over 50% less than race pads) and minimize noise and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Customers can choose between cross-drilled rotors, recommended for daily driven vehicles due to cooler operation, or slotted rotors, preferred for track-focused vehicles. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. While the provided fitment guide indicates compatibility with various Hyundai Sonata models from 2015-2018, it's crucial for buyers to confirm specific fitment for their vehicle's year, make, model, and trim using the available search tools, as the manufacturer notes that fitment issues can sometimes be confusing. If the sales team confirms fitment and the item does not fit, returns will be accepted provided the item is in like-new condition, without restocking fees.
