It seems on the ZL1’s the rear setup is just a pad change but the front is a larger caliper and rotor from the Caddy parts bin to offset the lack of heat dissipation from the loss of copper. I still haven’t found any performance comparison between the stock setup and copper free. Bigger deal on the SS’s but not sure about the ZL1’s.
