Can I use spacers on my 1999 Pontiac Sunfire?
Yes, but ensure the wheel spacers match the 5x100 bolt pattern and 57.1mm center bore. Also verify that you have enough thread engagement for your N 12x1.50 hardware.
Why is matching the 57.1mm center bore important for the 1999 Sunfire?
The 57.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
Fitment Checklist Before You Buy Wheels
