XRZERO NEXT GENERATION (ZERO DRAG) RACE CALIPERS
Wilwood’s next generation XRZERO race calipers combine decades of race experience, computer finite element analysis, and stateof-the-art machining into a race caliper that is lighter and stiffer, with zero drag. The unique high surface area body shape creates a caliper with superior brake fluid cooling and allows more air to flow through the rotor.
FEATURES:
• Optimized profile high-temperature seals for better piston retraction and zero drag
• Hard-anodized inside and out with durable Type III aluminum-oxide ceramic finish XRZ4R • No-bind retaining pins hold your choice of race compound brake pads
• Unique center X-bridge strengthens caliper without adding mass or obstructing airflow
• FEA design and precision machining results in a caliper weighing just 4.66 pounds - 1/2 pound less than a comparable Wilwood Superlite
• Innovative high surface area body removes unnecessary bulk, improving cooling without increased deflection
• Staggered-bore front calipers provide more even engagement and improved pad wear
• Thermlock® thermal barrier pistons and high-temperature seals reduce heat transfer to fluid
• Single-point bleed technology with low-profile bleed screws for more efficient fluid bleeding
• 0.80”/20.3mm thick brake pads for extended service life • Three piston sizes for front and rear use and 0.81” or 1.25” width rotors
• Includes 3/8-24 banjo bolt and fitting to connect caliper inlet to -3 flex line
