Ksport BKMZ320-445SO DualComp Dual Caliper Big Brake Kit with Caliper - 4-Piston

The Ksport DualComp Big Brake Kit (BKMZ320-445SO) is an all-in-one dual caliper braking solution engineered for drivers who demand independent foot brake and handbrake performance from a single, compact unit. Designed as a true bolt-on upgrade, this big brake kit delivers serious stopping power without the complexity of running two separate caliper systems.

DualComp System Technology:

At the heart of this kit is Ksport's innovative DualComp 4-piston caliper design. The single caliper houses four pistons — two dedicated exclusively to the foot brake circuit and two dedicated exclusively to the handbrake (e-brake) circuit. Each circuit operates completely independently on its own hydraulic system, ensuring precise, reliable actuation for both street driving and performance or motorsport applications.

Complete Kit Includes:

• 4-Piston DualComp Caliper(s) — dual-function foot brake and handbrake in one unit
• Floating Brake Disc(s) — high-performance rotor for improved heat dissipation and reduced brake fade
• Performance Brake Pads — matched to the caliper and rotor for optimal bite and modulation
• All Required Hardware — complete bolt-on installation hardware included

Key Features:

• Innovative single-caliper dual-function design replaces the need for a separate handbrake caliper
• Independent hydraulic circuits for foot brake and handbrake — no cross-interference between systems
• Floating rotor design reduces thermal distortion and extends pad and rotor life
• Complete bolt-on kit — everything needed for installation is included in the box
• Engineered for performance driving, motorsport, and rally applications requiring a dedicated handbrake

The Ksport BKMZ320-445SO DualComp Big Brake Kit is the ideal solution for performance and motorsport builds where a clean, integrated big brake setup with a fully functional handbrake is required. No fabrication or sourcing of additional components needed — just bolt on and go.
