Alfa Romeo wheels on Opel - hub centric rings

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

Original Alfa Romeo alloy wheels have a center bore of 58,1 mm and a bolt pattern (PCD) of 4x98. These wheels can be fitted to Opel vehicles with a hub diameter of 56,6 mm and a bolt pattern (PCD) of 4x100, but proper installation requires additional components.

You will need two products:

1. Hub centric rings – used to match the wheel center bore to the vehicle hub. They fill the gap between 58,1 mm and 56,6 mm, ensuring the wheel is properly centered. Without hub rings, the wheel may not sit correctly, which can cause vibrations and negatively affect driving safety.

2. Wobble bolts or wobble nuts – required to adapt the difference between the PCD 4x98 of Alfa Romeo wheels and the PCD 4x100 of Opel vehicles.

All hub centric rings in this category are designed for Opel hubs with a diameter of 56,6 mm and Alfa Romeo wheels with a center bore of 58,1 mm.

Wobble bolts or wobble nuts compensate for the difference between PCD 4x98 and PCD 4x100.
