2020 FIAT 124 Spider — Frequently Asked Questions
What is the bolt pattern for a 2020 FIAT 124 Spider?
The 2020 FIAT 124 Spider uses a 4x100 bolt pattern (also called lug pattern or PCD). The center bore is 54.1mm and the offset is 45mm.
What other years of FIAT 124 Spider have the same bolt pattern as the 2020?
The FIAT 124 Spider uses the 4x100 pattern from 2017 through 2020. Wheels from any of these model years are dimensionally compatible with the 2020, provided the offset and center bore also match.
Why is matching the 54.1mm center bore important for the 2020 124 Spider?
The 54.1mm 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.
