I just picked up a set of Akebono calipers from a wrecked G37. I know you have to remove the dust shield from the car and get the brackets to make it fit but are there any modifications i need to do to the caliper to make it fit. I think i remember reading the rear calipers needed to be shaved down or machined in order to fit. I've been searching but can't find a definitive answer. Please advise if possible. Thank you!
