There are two different sizes of brake rotors; used mostly on 98-01 cars. If your originally had 15 inch wheels, it will have the 11.1 inch brake rotors. If you had PHP, or 01+ model year, you'll have 11.7 inch rotors. This makes a difference in the knuckles. Measure your brake rotor on the donor vehicle and on yours to make sure you are getting the correct knuckle. Otherwise they are all compatible 98-04.
