Description

The Ksport Supercomp Big Brake Kit represents the pinnacle of brake upgrades, engineered to deliver uncompromising stopping power for your Mazda MX-5 Miata (2016-2018). This advanced, bolt-on system builds upon the capabilities of Ksport's Procomp kit by incorporating larger calipers, rotors, and pads, along with increased piston count and standard full-floating rotors. This design ensures superior self-centering and optimal performance under demanding conditions. Construction highlights include lightweight, forged one-piece calipers machined from aerospace-quality aluminum, providing exceptional strength and corrosion resistance. The aluminum pistons within the calipers offer superior heat dissipation. Carbon steel caliper brackets, CNC machined for precision, ensure a direct fitment to the OEM caliper bracket locations, simplifying installation. The kit comes standard with slotted rotors, recommended for vehicles used on the track, and includes SC5 Street Pads, designed for optimal performance on the street and occasional track use, with reduced dust and noise. Stainless steel braided brake lines are also included, offering a firmer pedal feel and quicker response by preventing line expansion under pressure. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. The product images shown are for illustration purposes only and may not be an exact representation of the product you receive. Ksport prioritizes fitment confirmation to minimize the risk of ordering the wrong product; if fitment is confirmed by their sales team and the item does not fit, they will facilitate a return with no restocking fees, provided the item is in like-new condition.
