Features and benefits:
• FNSL4R/ST calipers use a forged aluminum body and feature a Type III Mil-Spec, medium gray color hard anodized finish that provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout
• Thermlock pistons are used to reduce heat transfer from the pads to increase fade resistance, and extend service life by decreasing temperatures in the caliper body, fluid, and seals
• Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish
• Caliper piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls
• Calipers are also fully compatible with manual brake conversions to balance bar pedals using appropriately sized master cylinders.
• Spec 37 alloy GT Series directional vane 13 in. rotors are dynamically mounted using Wilwood Dynamic Lug Mounting system to forged aluminum hats
• Hats are hard anodized for superior wear resistance and extended service life at the load bearing surfaces
• Mounting brackets include all premium grade fasteners and secure the calipers to the uprights in the stock location with no modifications required
• High-temperature, high-friction, race compound pads selected specifically by application
