In the effort to build the ultimate 1/2 ton, dezert capable K5 I want to upgrade my brakes. Ive done a little research and found nothing that can help me really. No one makes a bolt on kit for bigger front rotors and calipers for my blazer. I would like to run something similar to this, but I dont think I need a caliper that large, but it would be nice. I would like to go with a 13" or larger rotor, but need the overall package to fit in a 17" wheel. I figure either way I go it I will need to have some custom parts made, and it wont be very cost effective, but it will do what I want it to do.
