Wilwood 140-14925 SX6R Big Brake Dynamic Front Kit 15.00in Rotors

The Wilwood SX6R Big Brake Dynamic Front Brake Kit (140-14925) delivers Wilwood's highest-capacity front braking solution for extreme duty, street/track, and show vehicles. The SX6R caliper was purpose-engineered for high-capacity braking with large-diameter rotors, and stands as the largest dual-purpose caliper Wilwood has produced — combining race-proven stopping power with a premium appearance suitable for both show and demanding dual-purpose use.

SX6R Caliper Technology:

• Forged aluminum caliper body — stress-flow forged from premium-grade aluminum alloy billet, realigning the metal's internal grain structure for superior strength-to-weight performance
• 6-piston radial mount design — 5.40 square inches of total piston area delivers massive, consistent clamping force under repeated hard-braking events
• Exclusive dust wiper seal system — protects piston bores from dust and corrosion for extended service life in all environments
• Compatible with rotors up to 15.00 inches — supports the largest rotor diameter in the Wilwood lineup for maximum thermal capacity

Rotor & Kit Specifications:

• 15.00-inch directional rotors with 72 staggered vanes for maximum airflow and sustained high-heat cooling
• Slotted rotor surface evacuates gases and brake dust to eliminate brake fade and maintain consistent bite
• Iron alloy rotor construction with aluminum hat — optimized thermal conductivity and lightweight performance
• Black powder coat finish on rotor hats for corrosion resistance and sharp visual contrast
• Radial caliper mount — factory disc spindle compatible; minimum 19-inch wheel diameter required

OE System Compatibility:

• Fully compatible with OE master cylinder output — no master cylinder upgrade required
• Retains factory ABS function without modification
• Provides enhanced braking capacity when paired with wheel and tire upgrades

The Wilwood 140-14925 SX6R Dynamic Front Kit is a complete big brake upgrade engineered for enthusiasts who demand race-level front braking performance without compromising street drivability or ABS compatibility. Kit includes calipers, rotors, rotor hats, and hardware.
