2005 Pontiac Gto

The wheel was then bolted on, and with the car in neutral, spun to ensure no binding or scraping of any parts. It turned just fine, and we didn't hear anything abnormal. (Attempts were made to spin the rotor without the wheel on, but it would seem the GTO's posi unit prevents the rotor from turning easily without the larger diameter of the wheel to help add turning torque. Regardless, it is better to have the wheel in place now, as it ensures the rotor is securely held against the hub, yielding the best representation of what the rotating clearances will be after final installation.)
