Installation Notes and Tips

Confirm rotor diameter, bolt pattern, and production date before ordering, especially on 1998 Volkswagen Jetta and 1995 Volkswagen Cabrio applications with date-specific fitment. This rotor is for the front left position only and uses a directional braking surface, so orientation matters during installation. Verify the vehicle’s existing rotor dimensions and inspect pads, caliper condition, and hub surface before assembly.
