2017 FIAT 124 Spider — Frequently Asked Questions
What is the bolt pattern for a 2017 FIAT 124 Spider?
The 2017 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 2017?
The FIAT 124 Spider uses the 4x100 pattern from 2017 through 2020. Wheels from any of these model years are dimensionally compatible with the 2017, provided the offset and center bore also match.
What does 45mm offset mean for the 2017 124 Spider?
An offset of 45mm means the wheel's mounting surface is 45mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your FIAT.
Can I put aftermarket wheels on my 2017 FIAT 124 Spider?
Absolutely. Just ensure the aftermarket wheels have a 4x100 bolt pattern, an offset near 45mm, and a center bore of at least 54.1mm (using hub rings if larger).
Can I use spacers on my 2017 FIAT 124 Spider?
Yes, but ensure the wheel spacers match the 4x100 bolt pattern and 54.1mm center bore. Also verify that you have enough thread engagement for your N 12x1.50 hardware.
Why is matching the 54.1mm center bore important for the 2017 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.
Fitment Checklist Before You Buy Wheels
- Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
