Fiat with wheels from Romeo - hub centric rings

Hub centric rings for Fiat hub (CB 56,6 mm / 56.6 mm, PCD 4x100) with Romeo wheels (CB 58,1 mm / 58.1 mm, PCD 4x98)

Fiat vehicles are equipped with a wheel hub diameter of 56,6 mm and a bolt pattern (PCD) of 4x100. When installing Romeo alloy wheels with a center bore of 58,1 mm and a bolt pattern (PCD) of 4x98, proper fitment requires specific components.

You will need two products:

1. Wheel hub centric rings – used to adapt the hub diameter to the wheel center bore. They eliminate the size difference between 56,6 mm and 58,1 mm, ensuring accurate alignment and stable mounting.

2. Wobble bolts or wobble nuts – designed to compensate for the difference between the PCD 4x100 of Fiat and the PCD 4x98 of Romeo wheels.

These hub centric rings are suitable for Fiat hubs with a diameter of 56,6 mm and Romeo wheels with a center bore of 58,1 mm.

Wobble bolts or wobble nuts allow safe installation between PCD 4x100 and PCD 4x98.
