ok so i trimmed the dust sheild. then removed all bolts holding the s14 caliper on, replaced the rotors, pads yoda yoda. when i bolted the q45 caliper back on everything was going smooth until i tightened the upper bolt on the spindle. as soon as you tighten the upper bolt it cause the the rotor to bind to a stop. any ideas what would cause this? ive searched many forum and ive never seen anything about spacing the caliper or anything like that.

HELPS PLEASE!!
