Installing Dic Brakes on a 14 bolt and want to know what is better, Calipers at the top behind the axle, Top in front of axle or under front or back. Wheel studs heads don't fit into recess groove on back of rotors they are to big but studs fit good in the hole, should they set in groove also. I think so but not sure? What is runout and how do I check it. Kit is from TSM and they say it should be .005 or less. Thought I would ask, Don't what to screw anything up with the brake system.
