Opel Insignia OPC wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2014 | Opel Insignia OPC Sports Tourer | 5x120 | 67.1 mm | 20x8.5J ET41 |

Factory wheel sizes on the Opel Insignia OPC
Across the 2 Opel Insignia OPC trims with a documented factory wheel, the OE diameter is 20 inch, width 8.5J and offset ET41. A forged wheel that keeps the 5x120 bolt pattern and the 67.1 mm hub bore and stays inside that offset range bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Vehicles With the Same Hub as the Opel Insignia OPC (5x120, 67.1 mm Bore)
In our database, 7 other vehicle entries from 4 makes use exactly the same 5x120 bolt pattern and 67.1 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x120 is used by 10.4% of the vehicle entries in our database (663 of 6,396); 1.7% of those also use a 67.1 mm center bore.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 20x8.5J | ET41 | 6.36 in (162 mm) | — | — |
| Flush | 20x9.5J | ET35 | 6.63 in (168 mm) | +7 mm | +19 mm |
| Maximum | 21x1J | ET30 | 6.68 in (170 mm) | +8 mm | +30 mm |
Hub-Centric Rings for a 67.1 mm Center Bore
A wheel with a center bore larger than 67.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.1 mm | 70.1 → 67.1 mm |
| 70.5 mm | 70.5 → 67.1 mm |
| 71.6 mm | 71.6 → 67.1 mm |
| 72.6 mm | 72.6 → 67.1 mm |
| 73.1 mm | 73.1 → 67.1 mm |
ANKUSI forged wheels are bored to exactly 67.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Opel Insignia OPC?
The Opel Insignia OPC uses a 5x120 bolt pattern with a 67.1mm center bore across every Insignia OPC variant in our database (2 guides, 2010–2014).
What is the Opel Insignia OPC center bore?
The hub-centric center bore is 67.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Opel Insignia OPC years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the Opel Insignia OPC?
Any wheel drilled 5x120 with a 67.1mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
