A1-211 Girodisc 2pc Front Brake Rotors for Camaro ZL1 (Gen 6)

A1-211 Girodisc 2pc Front Brake Rotors FITMENT: Chevy Camaro ZL1 (Gen 6), Front The Girodisc system is a direct replacement for the OE disc, but a different brake pad with an annulus (pad swept area) of 66mm or less must be used. We strongly recommend the Pagid 8081. This reduction in rotor annulus is done to keep the weight of the rotors low. The OEM rotors utilize a pillar vane design which is horribly inefficient in terms of dissipating heat. Since the OEM rotors heat-soak very easily, Chevrolet chose an easy solution to this problem: increasing the rotors' mass to combat that heat. We weighed an OEM rotor at 32.5 lbs. -- holy smoke! Girodisc took the functional route instead, engineering a shorter-annulus rotor ring for a total rotor-and-hat weight of 28.0 lbs. This design utilizes 72 directional cooling vanes for an incredibly efficient and robust package. The necessary pad shape is very common, found on other Camaro and Corvette applications equipped with six-piston calipers. If
