[High Plains Mopars]

There are actually a selection of 1.25 thick, 12.19 diameter rotors from a variety of manufacturers. If you sticking with the .81 wiloods just because that's what came in the kit, I'd have to ask what have you done in pad selection to make them work better, and if your really concerned about mass, why haven't you stepped up to the thicker versions? There are a couple of mopar guys running the .81 thick wilwoods on road courses pretty succesfully, but they both said pad compound selection is key to making them work.
