Ksport BKBM321-445SO DualComp Big Brake Kit Dual Caliper System - 4-Piston

The Ksport DualComp Big Brake Kit (BKBM321-445SO) is a complete, bolt-on dual caliper braking solution engineered for drivers who demand independent control over their foot brake and handbrake systems. Designed as an all-in-one upgrade, this kit eliminates the need for separate brake components by integrating both functions into a single, purpose-built 4-piston caliper.

DualComp System Overview:

Ksport's proprietary DualComp technology uses a single 4-POT caliper divided into two dedicated circuits: 2 pistons dedicated to the foot brake and 2 pistons dedicated to the handbrake. Each circuit operates completely independently on its own hydraulic system, ensuring precise, interference-free response from both braking inputs — a critical advantage for performance driving and motorsport applications.

What's Included:

• 4-Piston DualComp Caliper(s) — dual-function design with independent foot brake and handbrake circuits
• Floating Brake Disc(s) — for improved heat dissipation and reduced brake fade
• Brake Pads — matched to the caliper for immediate performance out of the box
• All Required Hardware — complete bolt-on installation hardware included

Key Features:

• True bolt-on fitment — no custom fabrication required
• Independent hydraulic circuits for foot brake and handbrake
• 4-piston caliper construction for even pad wear and consistent clamping force
• Floating rotor design reduces thermal distortion and extends rotor life
• Complete kit — everything needed for installation is included

The Ksport DualComp Big Brake Kit is the ideal solution for motorsport competitors and performance enthusiasts seeking a reliable, high-performance braking upgrade that handles both daily braking and handbrake demands without compromise.
