I look online and see many different brakes and rotors to choose from. do anyone know exactly what i should get by my vin number. I see some rotors that are 321mm and some that are 288mm. And I also see 4pad system and 8 pad systems and some with sensors and some without. How can i find out exactly what i need without taking the wheel off. My Vin WAUZL64B91N157072. if that helps.
