Wilwood - XRZero Race Calipers

Wilwood – XRZero Race Calipers

Wilwood XRZero Race Calipers represent the next generation of race brake technology, combining decades of racing experience, advanced finite element analysis (FEA), and state-of-the-art CNC machining. The result is a caliper that is lighter, stiffer, and truly zero-drag, delivering consistent braking performance with reduced heat and wear.

The XRZero’s high surface area body design improves brake fluid cooling while allowing increased airflow through the rotor. A unique center X-bridge reinforces the caliper body without adding weight or restricting airflow, making this caliper both extremely rigid and thermally efficient.

At just 4.66 lbs, the XRZero is ½ lb lighter than a comparable Wilwood Superlite, while offering improved stiffness, cooling, and pad life.

Features & Benefits

• Zero-drag design – Optimized high-temperature seals improve piston retraction
• Center X-bridge construction – Increases stiffness without added mass
• Ultra-lightweight – Weighs only 4.66 lbs
• High surface area body – Improves cooling with reduced bulk and deflection
• Hard anodized finish – Type III aluminum-oxide ceramic coating inside and out
• Staggered-bore front calipers – More even pad engagement and wear
• Thermlock® pistons – Reduce heat transfer to brake fluid
• Single-point bleed system – Faster, more efficient bleeding
• No-bind retaining pins – Secure pad retention with easy service
• Thick race pads – 0.80" / 20.3mm pads for extended service life
