I scored a set of brackets to put viper calipers on the rear.
But I wont be able to fit them on the front without spacing the wheels I have found. I wont do that. So I am looking at a few sets of 4 piston calipers that will clear my 17 inch wheels.

At this point the brackets are what I like to see. Thanks for those pics. Seems pretty simple and straightforward. I'll have a lot better picture when the calipers are in my hands for mockup.
