Ksport BKAC021-332CO Slimline Front 3-Piston Big Brake Kit with 13 in. Drilled Rotors

The Ksport BKAC021-332CO Slimline Big Brake Kit is engineered to deliver serious braking performance without sacrificing wheel fitment. Traditional big brake kits use large multi-piston calipers that simply don't clear the back of aggressive or low-offset wheels — the Ksport Slimline solves this with a caliper profile matched to OEM single-side floating piston caliper thickness, making it compatible with most factory wheels and wheels with very limited brake caliper clearance.

At the heart of this kit is a 3-piston Slimline caliper forged from aerospace-grade billet aluminum in a one-piece construction — not cast or welded — for superior strength and consistent wall thickness throughout. Aluminum caliper pistons are protected by high-temperature seals rated for racetrack use, while titanium brake pad retainer clips and stainless-steel brake pad wear plates are included as standard. Stainless-steel braided brake lines are also included, eliminating hose expansion under hard braking for a firmer, more responsive pedal feel.

The two-piece floating brake disc measures 332mm and features a drilled rotor face for improved heat dissipation and bite. The lightweight 6061-T6 aircraft-grade aluminum center bell significantly reduces rotational mass, with Ksport rotors commonly weighing up to 50% less than OEM rotors of equivalent size.
