What are actually having done? I have my pistons done by Swain Tech, but people with a home kit can accomplish the same thing. I am having my brake calipers modified by a local race shop to use thermal insulated pistons and 600 degree brake fluid.
I have owned my Vette for many years and only now has it ever required other than the stock brake setup. Only a Road racing Vette doing lap after lap can exceed stock brakes. Not required on the street. Just fresh Dot 4 oil and good pads
