Product Details

The Ksport SuperComp Big Brake Kit (BKIN420-971SO) delivers maximum stopping power with advanced brake technology engineered to dramatically reduce brake fade, continuously cool the brake pad surface, and maintain consistent performance under repeated hard braking. Designed for straightforward installation with minimal tooling required in most applications, this kit is an ideal upgrade for enthusiasts demanding more from their braking system.

SuperComp Caliper Features:

  • Differential bore configuration with significantly larger pistons than the ProComp caliper series
  • Machined from aircraft-quality billet aluminum for superior strength-to-weight ratio
  • Weighs just over 7 lbs. per caliper for reduced unsprung weight
  • Machined-in protection grooves for bridge tube safety
  • Aluminum pistons with high-temperature seals for thermal resilience
  • Stainless steel brake pad wear plates included as standard
  • 4 brake pads per caliper for extended pad life and even wear distribution
  • Opposed piston design improves pad wear consistency and caliper rigidity over OEM designs

2-Piece Floating Disc Assembly:

  • Reduces both rotating and unsprung weight for improved handling dynamics
  • Floating design prevents thermal warping and eliminates braking surface cupping caused by extreme heat
  • Unique slot design reduces braking noise and expels gas and pad debris more effectively than conventional slots
  • Every rotor is heat treated and balanced before shipment for optimal, consistent performance

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

Rotor Style Guide:

  • Cross-drilled rotors run cooler and are recommended for daily-driven street vehicles
  • Slotted rotors are recommended for vehicles that see frequent track use

The Ksport SuperComp Big Brake Kit is the top-tier choice for drivers seeking race-proven braking performance with a lightweight, precision-engineered system built to handle the most demanding conditions on street or track.

Easy

great service!

Everything was good

The only thing negative I can say is I didn't receive emails stating the item was shipped with a tracking number. I did receive the part quickly so I can complain too much about the lack of emails. I will use Autoplicity again in the future.

great experience

Everything was as expected

good price and easy

Easy enough... we'll see if it arrives.
