Product Description
The HBS Universal Racing Modified Brake Caliper (7L6615123Q) is a monoblock 6-piston system designed for high-performance vehicles requiring extreme braking precision. Racing calipers work by evenly distributing hydraulic pressure across multiple pistons (φ38, φ34, φ30), ensuring maximum clamping force on 330mm-358mm discs. This reduces brake fade during track use while maintaining street durability.
Fits Porsche Cayenne, Audi Q7, VW Touareg, Nissan GTS, Infiniti FX35, Audi A6/A4, and Toyota Camry. The monoblock construction eliminates flex under high-pressure (13.7MPa), ideal for motorsport applications and performance upgrades.
