5x112 Centre Bore Adapter (57.1mm to 66.6mm)
What's included
In every kit
2× hubcentric PCD adapters — bored to 57.1mm → 66.6mm, 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 Centre Bore Adapter (57.1mm to 66.6mm)
Unlike the rest of our PCD adapter range, this one doesn't change the bolt pattern — both sides are 5×112. It corrects the centre bore, from the 57.1mm hub used on Audi A3/S3/RS3, TT, R8, VW Golf Mk5–8, Bentley Continental GT/Flying Spur and Lamborghini Gallardo/Huracán, up to the 66.6mm bore used on bigger-hub Audi A4/A6/Q5, Mercedes and BMW G-series wheels. Also known as a wheel adapter or hub-centric adapter — it's the same part.

Because the bolt pattern is identical on both sides, this adapter's job is purely to correct the centre bore — the vehicle-side face is machined to 57.1mm to locate precisely on your existing hub, and the wheel-side register is machined to 66.6mm so bigger-hub wheels centre correctly instead of relying on the bolts alone to hold them in position. Both platforms share the same M14×1.5 ball-seat bolt family, so in many cases your existing bolts may already be the correct length and thread — confirm with us before ordering hardware separately.
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 Centre Bore Adapter FAQ
Does this change my bolt pattern?
No — this specific adapter keeps the 5×112 pattern on both sides. It only corrects the centre bore, from 57.1mm up to 66.6mm, so that wheels designed for a bigger hub sit centred and secure on your car.
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, as well as Bentley Continental GT/Flying Spur and Lamborghini Gallardo/Huracán. 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 5×112 wheel with a 66.6mm centre bore — the standard bore for bigger Audi A4/A6/A7/Q5/Q7, Mercedes, and BMW G20/G30-generation wheels.
Do I need new bolts for this?
Often not — both platforms use the same M14×1.5 ball-seat bolt family, so your existing bolts may be the correct thread and just need checking for length against your chosen thickness. Contact us with your car and wheel details and we'll confirm, or source new ones if needed.
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.
