Three adapter types. Clear starting prices.
Same bolt pattern as your vehicle, different hub. Most straightforward conversion.
Bolt pattern conversion in one piece — e.g. 5×112 → 5×120.
For conversions where the hub's bolt pattern and the wheel's bolt pattern would clash in a single piece, or where a stud hub needs the adapter thinner than the stud protrusion. Get in touch for an exact quote.
Any bolt pattern. Any hub. Machined here.
If your wheels don't match your hub — or you're building something no off-the-shelf part covers — we machine the adapter from scratch. Every job starts with your measurements and ends with a part that fits first time.
When you need a two-piece adapter
Most conversions are handled with a single-piece adapter. A two-piece design is only needed in two specific situations — and knowing which applies to your setup helps us quote accurately first time.
Straightforward — one piece works
The hub has threaded holes and the wheel is held on with bolts that thread directly into the hub. Adding an adapter simply adds length to the bolt, so a one-piece adapter is normally all that's needed — we just specify longer bolts to maintain proper thread engagement for the thread pitch involved.
Hub and wheel bolt patterns overlap
If the hub's bolt circle and the wheel's bolt circle are close enough in diameter, the holes for each pattern can land on top of each other, leaving no solid material to drill both cleanly in a single piece. A two-piece adapter solves this — the first piece bolts to the hub on its own bolt circle, and a separate second piece carries the wheel's bolt pattern, mounted to the first piece's face. Keeping the two patterns in separate pieces means they never have to share the same material.
Adapter thinner than the stud protrusion
The studs are pressed into the hub and project a fixed length. For a PCD conversion, the goal isn't to fit the wheel over these existing studs — it's to hide them entirely within the depth of the adapter, so the wheel sits flush against a clean face with its own bolt pattern. There are two ways this works:
- If the adapter is thicker than the stud protrusion, the studs sit fully recessed inside the adapter body, and a one-piece adapter can be used.
- If the adapter needs to be thinner than the stud protrusion, a two-piece adapter is used — the first piece bolts to the hub and fully encloses the studs, and the second piece (carrying the new bolt pattern) mounts to the front face, keeping the overall stack as thin as required.
If you're not sure which of these applies to your vehicle, send us the make, model, hub PCD, wheel PCD, and a photo of the hub — we'll check for any clash or clearance issue and recommend the right design before quoting.
What's included with every adapter
| Material | 6082-T6 or 6061-T6 aluminium billet |
| Machining | CNC milled in-house for precise, repeatable fitment |
| Tolerance | ±0.02mm across all bores and bolt patterns |
| Bolt patterns | 3, 4, 5, 6 or 8 stud — any PCD |
| Thickness | 10–30mm typical, custom on request |
| Centre bore | Machined to match your hub, so the adapter centres precisely on the vehicle with no play |
| Hardware | Grade 10.9 high-tensile steel studs or bolts |
| Finish | Black anodised, silver anodised, or Cerakote — anodising and Cerakote finishes are charged as an additional cost on top of the base price |
| Engraving | Laser logo marking available |
| Lead time | 2–3 weeks from confirmed specification |
Every adapter is machined to fit the hub it's being made for, so it locates precisely on the vehicle with no play. This is why the parts run without vibration.
