Ksport BKFD330-445SO DualComp Big Brake Kit Dual Caliper - 4-Piston

The Ksport DualComp Big Brake Kit (BKFD330-445SO) is an all-in-one dual caliper braking solution engineered for drivers who demand independent control over their foot brake and handbrake systems. Designed as a direct bolt-on upgrade, this kit delivers competition-grade stopping power without the complexity of custom fabrication.

DualComp Caliper Technology:

• Single 4-piston caliper design splits function between two independent braking circuits
• 2 pistons dedicated to the foot brake — providing consistent, progressive pedal response
• 2 pistons dedicated to the handbrake — allowing precise rear brake bias and drift/competition control
• Each circuit operates fully independently on its own hydraulic system

Complete Bolt-On Kit Includes:

• DualComp 4-piston calipers
• Floating brake disc rotor
• Performance brake pads
• All required installation hardware

The floating brake disc reduces heat transfer to the hub and helps prevent warping under aggressive braking conditions, making this kit well-suited for track use, motorsport competition, and performance street driving. As a complete kit, all components are matched and pre-validated to work together — no sourcing individual parts or compatibility guesswork required.
