Ksport BKMS011-961SO Supercomp Front 8-Piston Big Brake Kit 15.7 in. Slotted Rotors

The Ksport BKMS011-961SO Supercomp Big Brake Kit is Ksport's most extreme brake upgrade, engineered to deliver the highest level of stopping power without requiring any vehicle modifications to install. This sophisticated bolt-on big brake kit surpasses the ProComp series with larger calipers and rotors, more pistons, increased pad surface area, and standard full-floating two-piece rotor design for superior braking performance on both street and track.

Lightweight Forged One-Piece Calipers:

The Supercomp calipers are machined from a single solid billet of aerospace-grade aluminum rather than being cast or welded together. This one-piece construction delivers perfectly uniform wall thickness throughout the caliper body, eliminating the weak spots that lead to fracturing, warpage, and long-term failure. Caliper pistons are aluminum for superior heat resistance and are protected by heavy-duty seals rated for racetrack temperatures. Calipers are available in standard painted finishes including Orange, Red, Black, and Yellow, with optional premium upgrades in Silver, Gold, and Titanium high-polish or anodized colors.

Floating Two-Piece Rotor Design:

Floating two-piece rotors are standard on all Supercomp brake systems. The outer rotor section is designed to shift slightly under load for better self-centering in the caliper, which lowers brake drag and promotes more even pad application. Two-piece rotor construction also significantly reduces unsprung and rotating weight — Ksport rotors commonly weigh up to 50% less than OEM rotors of the same size. Rotors are available in Cross Drilled or Slotted styles. Cross drilled rotors run cooler and are recommended for daily driven vehicles, while slotted rotors are the preferred choice for track use.

CNC Machined Carbon Steel Caliper Brackets:

Every Supercomp kit includes CNC machined carbon steel caliper brackets that allow the much larger Ksport calipers to bolt directly to the OEM caliper bracket location with no vehicle modifications required in most applications.

DOT-Compliant Stainless Steel Braided Brake Lines:

D.O.T. compliant stainless steel braided brake lines are included with every kit. These lines resist expansion under pressure to deliver a firmer, more responsive pedal feel compared to stock rubber lines.

• 8-piston forged aluminum front calipers
• 15.7 in. (400mm) slotted floating two-piece brake rotors
• SC5 Street / NAOC Ceramic brake pads
