Audi S1 wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2015 | Audi S1 | 5x100 | 57.1 mm | 18x7.5J ET38 |
| 2015 | Audi S1 Sportback | 5x100 | 57.1 mm | 18x7.5J ET38 |
Factory wheel sizes on the Audi S1
Across the 2 Audi S1 trims with a documented factory wheel, the OE diameter is 18 inch, width 7.5J and offset ET38. A forged wheel that keeps the 5x100 bolt pattern and the 57.1 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 Audi S1 (5x100, 57.1 mm Bore)
In our database, 73 other vehicle entries from 10 makes use exactly the same 5x100 bolt pattern and 57.1 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.
5x100 is used by 1.9% of the vehicle entries in our database (124 of 6,503); 69.4% of those also use a 57.1 mm center bore.
Hub-Centric Rings for a 57.1 mm Center Bore
A wheel with a center bore larger than 57.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 57.1 mm |
| 63.4 mm | 63.4 → 57.1 mm |
| 64.1 mm | 64.1 → 57.1 mm |
| 65.1 mm | 65.1 → 57.1 mm |
| 73.1 mm | 73.1 → 57.1 mm |
ANKUSI forged wheels are bored to exactly 57.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Audi S1?
The Audi S1 uses a 5x100 bolt pattern with a 57.1mm center bore across every S1 variant in our database (2 guides, 2015).
What is the Audi S1 center bore?
The hub-centric center bore is 57.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Audi S1 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 Audi S1?
Any wheel drilled 5x100 with a 57.1mm 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.
