5x110 to 5x112 PCD Adapter (65.1mm to 57.1mm)
What's included
In every kit
2× hubcentric PCD adapters — bored to 65.1mm → 57.1mm, in your chosen thickness
Supplied without wheel bolts — this kit does not include hardware. Your existing bolts will be too short once the PCD adapter is fitted, so you'll need a set of extended bolts matched to your PCD adapter's thickness. Get in touch and we can source these for you, or fit your own.
5x110 to 5x112 PCD Adapter (65.1mm to 57.1mm)
Converts a 5×110 hub (65.1mm bore) to run 5×112 wheels with a 57.1mm centre bore — built for owners of Alfa Romeo Giulia and Stelvio (2016 on), Maserati MC20 and Maserati GranTurismo/GranCabrio (2023 on) who want to fit smaller-hub 5×112 wheels such as those from Audi A3/S3/TT or VW Golf. Also known as a wheel adapter or bolt pattern adapter — it's the same part.

Each adapter is hubcentric on both faces — the vehicle-side bore is machined to 65.1mm to locate precisely on your existing 5×110 hub, and the wheel-side register is machined to 57.1mm so 5×112 wheels centre correctly with no reliance on the bolts alone. The adapter bolts to your hub using extended bolts through the vehicle's original threaded holes, and the wheel then bolts directly onto the adapter's own threaded 5×112 holes. Extended bolts matched to your chosen thickness are required and sold separately. Note: this is a different centre bore to our other 5×110-to-5×112 adapter, which targets the larger 66.6mm bore used by bigger-hub Audi, Mercedes and BMW G-series wheels — check which wheel you're fitting before choosing between the two.
Fitment note: the makes and models listed above are a guide to vehicles commonly using this hub and bore combination — they are not a guarantee of fitment. Specifications can vary by trim, model year and market, so please confirm your exact vehicle's PCD and centre bore before ordering. If you're at all unsure, contact us with your vehicle details and we'll confirm fitment before you buy.
5x110 to 5x112 Adapter FAQ
Will this fit my Alfa Romeo Giulia or Maserati MC20?
Yes — this adapter is machined specifically around the 5×110, 65.1mm hub shared by Alfa Romeo Giulia/Stelvio (2016 on), Maserati MC20 and Maserati GranTurismo/GranCabrio (2023 on). Older Maserati models — Ghibli, Quattroporte and Levante — use a different pattern (5×114.3, 67.1mm) and are not covered by this adapter.
Which wheels can I fit with this?
Any 5×112 wheel with a 57.1mm centre bore — the smaller-hub pattern used on Audi A3/S3/RS3, TT, R8 and VW Golf Mk5–8. If your target wheel uses the larger 66.6mm bore instead (common on bigger Audi, Mercedes and BMW G-series wheels), you need our other 5×110-to-5×112 adapter, not this one.
Do I need to buy new bolts, or can I reuse my existing ones?
Yes, new bolts are needed. Contact us with your car and wheel details and we can source the correct bolts for you at an extra cost.
What thickness should I choose?
15mm gives a subtle offset change, 20mm is the most common choice for a noticeable stance improvement without pushing clearances, and 25mm is more aggressive — check clearance against your arch and suspension components before choosing 25mm.
Is this adapter hubcentric on both sides?
Yes. The vehicle-side face is machined to 65.1mm to locate on your 5×110 hub exactly as your original wheel does, and the wheel-side face is machined to 57.1mm so 5×112 wheels centre on the adapter itself rather than relying on the bolts to hold the wheel in position.
