What's included

In every kit

2× hubcentric PCD adapters — bored to 57.1mm (both sides), 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.

5x112 to 5x100 PCD Adapter (57.1mm)

Converts a 5×112 hub to run 5×100 wheels — both share the same 57.1mm centre bore, so only the bolt pattern changes. Built for owners of Audi A3/S3/RS3, TT, R8 and VW Golf Mk5–8 who want to fit wheels from older VW Group cars (Golf III/IV, Jetta, Corrado, Passat B3/B4, Audi TT Mk1). Also known as a wheel adapter or bolt pattern adapter — it's the same part.

Material	6082-T6 billet aluminium
Made in	UK

Because both platforms share a 57.1mm centre bore, this adapter's main job is bolt pattern conversion — the vehicle-side face is machined to locate precisely on your existing 5×112 hub, and the wheel-side register accepts 5×100 wheels which centre correctly on the same 57.1mm bore 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 5×100 holes.

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.

5x112 to 5x100 Adapter FAQ

Will this fit my Audi A3, TT or VW Golf?

Yes — this adapter is machined specifically around the 5×112, 57.1mm hub used on Audi A3/S3/RS3, TT, R8 and VW Golf Mk5–8. If you're unsure whether your specific model or year shares this hub, send us your details before ordering.

Which wheels can I fit with this?

Any 5×100 wheel with a 57.1mm centre bore — the pattern used on older VW Group cars including Golf III/IV, Jetta, Corrado, Passat B3/B4 and Audi TT Mk1.

Does the centre bore change with this adapter?

No — both platforms already share the same 57.1mm bore, so this adapter is purely a bolt pattern conversion rather than a bore correction.

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.
