Ksport BKBM070-621CO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKBM070-621CO is a floating rotor big brake kit engineered to deliver maximum stopping power while significantly reducing brake fade. Available with 4, 6, or 8 piston caliper options, this system is designed for performance-minded drivers who demand reliable, consistent braking under both street and track conditions.

At the heart of the kit is a differential bore, opposed piston caliper CNC machined from aircraft-quality billet aluminum. Each caliper weighs just over 5 lbs. and features machined-in protection grooves for the bridge tubes. The opposed piston configuration improves pad wear consistency and caliper rigidity over OEM designs. Standard caliper appointments include aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates.

The kit uses a 2-piece floating disc assembly that reduces both rotating and unsprung weight. The floating design isolates thermal stress caused by extreme heat, preventing disc warping and braking surface cupping. Each rotor features a unique slot pattern that minimizes braking noise while expelling gas and pad debris more efficiently than conventional slotted designs. Every rotor is heat treated and balanced prior to shipment to ensure optimal performance right out of the box.
