What are the right side rotors
What side rotors for a 2002 mercury cougar 2.5l v6
For your vehicle, you can use two different rotor sizes, so I understand why you are asking. If your car has the 15" wheels and tires, purchase the 260mm diameter rotors. If you have the 16" wheels and tires, then you can purchase the 278mm rotors. Good Luck!
