      ls1 rear rotor specs

      If it's on here, I couldn't find it. Can anyone provide the max & min thickness specs for a ls1 rear rotor? Are lt1 the same? I'm trying a home brew of brake parts. Thanks!

      Thanks for the response! Unfortunately it seems that ls1 rotors may not work for me. I need something that is 12.8 x 0.78 with 5 on 4.75" bolt circle or as close as possible.

      Did you find that information online somewhere? I couldn't find anything that specific using google.
