The new Astro rotors that I have are .275" thick where they bolt up to the axle flanges. The Impala SS rotors are .245" thick, so only .030 thicker. A used set of Astro rotors that I have here have the stamped steel hat that is about .125" thick. However I don't know if that style is still available. Yes the Astro rotors are available cross drilled and zinc plated.

Do you know if we can get them cross drilled & zinc plated?
