These are bolt on kits. No cutting or flaring. Do not have to remove the knuckle for machining.
They will clear most 15” wheels. These are the absolute lightest brake and offer the most clearance out of any bolt on solution currently. These rears WILL eliminate the e brake because they use a lightweight aluminum hat. They save approx 45-46 lbs vs stock rear brakes and are 20-25 lbs lighter than other rear brake options to clear 15s
They are offered in a vented street rotor and a solid thin drag rotor.
