Wilwood 140-18191 Features:

AERO6R/ST six piston radial mount race calipers are coupled with the high cooling capacity of burnished, race-ready 15.00in dynamically mounted Lug-Drive Spec37 GT directional vane rotors to provide the ultimate brake package for unrestricted road race competition. AERO6R/ST calipers use a forged aluminum body and feature a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores and high resistance to abrasion and corrosion throughout. This latest model of the AERO6R/ST calipers features a wider-than-standard body that accepts 20mm thick pads to add volume for longer service life. Thermlockandreg; pistons are used to reduce heat transfer from the pads to increase fade resistance and extend service life with decreased temperatures in the caliper body, fluid, and seals. Internal damper springs and controlled retraction, as well as 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. The calipers are also fully compatible with manual brake conversions to balance bar pedals using appropriately sized master cylinders. Spec37 alloy GT series directional vane rotors are dynamically mounted using our new Lug Drive mounting system to forged aluminum hats. As with the calipers, the hats are hard anodized for superior wear resistance and extended service life at the load-bearing surfaces. Mounting brackets, including all premium-grade fasteners, secure the calipers to the uprights in the stock location with no modifications required. This championship-proven system is completed with high-temperature, high-friction, race compound pads selected specifically by application. Installation requires the separate purchase of the stainless steel braided Flexline kits that must be ordered according to the model year.
