Expert Buying Guide for 2017 FIAT 124 Spider
The 2017 FIAT 124 Spider uses a 4x100 bolt pattern with a 54.1mm center bore. When selecting aftermarket wheels, hub-centric rings are essential to match the bore precisely, preventing vibrations and ensuring proper load distribution. The factory offset is 45mm; deviations beyond ±5mm may cause rubbing or clearance issues with suspension and body components. Always use lug nuts with the correct thread pitch (12x1.50) and seat type—either conical (60-degree) or ball seat—to match the wheel. Incorrect lug nuts can lead to wheel loosening or damage. Verify that aftermarket wheels are hub-centric or use appropriate rings for safe installation.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using universal fit wheels without hub-centric rings; they can cause vibration and stress on studs.
- ✅ Check inner clearance for aftermarket wheels; the 124 Spider has limited space near the strut and fender liner.
- ⚠️ 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).

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.
