Ksport BKMZ100-445SO DualComp Big Brake Kit Dual Caliper with Floating Disc - 4-Piston

The Ksport BKMZ100-445SO DualComp Big Brake Kit is a complete dual-caliper braking solution engineered for drivers who demand independent foot brake and handbrake performance from a single, compact 4-piston caliper assembly. Designed as a true bolt-on upgrade, this kit provides enhanced stopping power and precision control for motorsport and high-performance street applications.

Ksport's innovative DualComp system splits a single 4-piston caliper into two independent circuits — 2 pistons dedicated to the hydraulic foot brake and 2 pistons dedicated to the handbrake (e-brake/parking brake). Each circuit operates entirely independently on its own hydraulic system, eliminating interference between braking inputs and improving overall brake bias control.

Key Features:

• 4-Piston Dual-Function Caliper — 2 pistons for foot brake, 2 pistons for handbrake in a single caliper body
• Independent Hydraulic Circuits — foot brake and handbrake operate on completely separate systems
• Floating Brake Disc — reduces heat transfer and minimizes disc warping under repeated high-load braking
• Complete Bolt-On Kit — includes everything needed for a direct installation with no fabrication required
• High-Performance Brake Pads Included — matched to the caliper and rotor for optimal initial performance
• All required mounting hardware included

Kit Includes:

• DualComp 4-Piston Caliper(s)
• Floating Brake Disc(s)
• Brake Pads
• All required hardware

The Ksport DualComp Big Brake Kit is ideal for rally, drift, time attack, and track day competitors who require reliable, independent handbrake engagement without compromising foot brake performance. As a complete kit, installation is straightforward and requires no custom fabrication.
