Product Details

The Ksport SuperComp Big Brake Kit (BKIN420-951SO) delivers maximum stopping power engineered for high-performance street and track applications. Incorporating advanced brake technology, this system is specifically designed to reduce brake fade, continuously cool the brake pad surface, and refresh pad contact under repeated heavy braking. Installation is straightforward and requires minimal tools in most applications.

SuperComp Caliper Features:

  • Differential bore configuration with larger pistons than Ksport ProComp calipers for increased clamping force
  • Machined from aircraft-grade billet aluminum for an ultra-lightweight construction — just over 7 lbs. per caliper
  • Machined-in protection grooves for bridge tube durability
  • Aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates included as standard
  • Opposed piston caliper design for improved pad wear and superior caliper rigidity over OEM
  • 4 brake pads per caliper for maximum pad surface coverage

2-Piece Floating Disc Assembly:

  • Reduces both rotating and unsprung weight for improved handling dynamics
  • Floating design prevents thermal warping and disc surface cupping under extreme heat
  • Unique slot pattern expels gas and pad debris more efficiently than conventional slotted designs, reducing braking noise
  • Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance

Stainless Steel Braided Brake Lines are included to eliminate hose expansion under pressure, delivering a firm, consistent pedal feel.

Rotor Style Guide:

  • Cross Drilled: Runs cooler under moderate use — recommended for daily driven vehicles
  • Slotted: Optimized for aggressive heat cycling — recommended for track or performance driving

The Ksport SuperComp Big Brake Kit represents the pinnacle of Ksport's brake lineup, combining lightweight billet construction, advanced thermal management, and race-proven caliper geometry into a single comprehensive upgrade package.

The gentleman I spoke to was very kind and gave me a coupon code to use to help with the shipping that was almost as much as the item. Much appreciated.

Very easy checkout.

Another website offered an warranty for the auto parts if they were not working properly or just in poor condition and etc.

Had no problems

Looking forward to the shipment. Hoping it's exactly what I need. Thanks
