i'm looking at upgrading my front and rear brakes. i'm going to go with the 11.6" rotors front and rear both vented i just want to know what would be the best calipers to get. i 'm also wondering off what vehicles can i get the caliper brackets off of for the upgrade so i can just find some at a junk yard instead of having to by new. and with converting the rear all i need is the knuckle, hub, lines and the e-brake cable? what specificity do i need for the e-brake cable? and do i really need the backing plate?
