AERO4R/ST four piston radial mount race calipers are coupled with the high cooling capacity of 14.00" Dynamic 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 AERO4R/ST calipers features a wider than standard body that accepts 20mm thick pads to add volume for longer service life. Thermlock® pistons are used to reduce heat transfer from the pads to increase fade resistance.
