This upgrade kit is a direct fit that works great and my car can stop on a dime. Only gave it 4 out of 5 stars because when they package the calipers, they leave the bracket and bolts in a plastic bag right next to the calipers without anything between them besides the plastic of the bag and it scratched up the powder coating on the calipers down to the metal in some places. Nothing a little red sharpie can't hide but it's still annoying just knowing its scratched.
