Product Details

The Ksport BKSB020-611SO ProComp Big Brake Kit delivers a significant upgrade in stopping performance over factory brake systems. Engineered to dramatically reduce brake fade while continuously cooling and refreshing the pad surface under repeated heavy braking, this big brake kit is a sophisticated bolt-on upgrade that requires no vehicle modifications in most applications.

Aircraft-Grade Billet Aluminum Calipers:

  • Available in 4, 6, or 8 piston configurations to match your performance requirements
  • CNC machined from a single solid billet of aircraft-grade aluminum — not cast or welded — for perfectly even wall thickness and maximum strength
  • Opposed piston design significantly improves pad wear and caliper rigidity over OEM
  • Aluminum pistons provide better heat resistance and uncompromised operation under extreme temperatures
  • High-temperature seals and stainless-steel brake pad wear plates included on every caliper
  • Machined-in protection grooves for bridge tubes; each caliper weighs just over 5 lbs.

Two-Piece Floating Rotor Assembly:

  • Lightweight two-piece disc construction reduces both rotating and unsprung weight — often up to 50% lighter than comparable OEM rotors
  • Floating outer disc section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and delivering more even pad application
  • Floating design eliminates thermal stress distortion, preventing disc warping and braking surface cupping under extreme heat
  • Unique slot pattern expels gas and pad debris faster than conventional slot designs, reducing braking noise
  • Every rotor is heat treated and precision-balanced before shipment
  • Choose Cross Drilled rotors for street/daily-driven use (run cooler) or Slotted rotors for track-focused applications

Complete Kit Contents & Additional Features:

  • Includes calipers, floating brake disc, NAOC ceramic brake pads, D.O.T.-compliant stainless-steel braided brake lines, and all required hardware
  • Stainless-steel braided lines eliminate hose expansion under pressure for a firmer, more responsive pedal feel
  • NAOC ceramic pads optimized for street and occasional track use; operating range 194°F – 1,022°F
  • CNC machined carbon steel caliper brackets included for direct bolt-on fitment to OEM bracket locations
  • OEM ABS systems remain fully functional
  • Available caliper finish options include Orange, Red, Black, Yellow, and premium anodized colors
  • Backed by a 12-month manufacturer defect warranty

The Ksport ProComp Big Brake Kit is the ideal performance brake upgrade for enthusiasts seeking improved stopping power, reduced fade, and a sportier pedal feel on the street or occasional track day.
