GN4R Big Brake Lug Drive Front Brake Kit (Race)
GN4R/ST four piston radial mount race calipers are coupled with the high cooling capacity of 13.00" Dynamic Lug Drive Spec37 GT 48 directional vane rotors to provide the ultimate brake package for road race competition restricted to four piston calipers. GN4R/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 GN4R/ST calipers features a 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. BP-35 SmartPads selected specifically for exceptional driver control in braking.
