OX-D5 Quantum
The OX-D5 Quantum is a two-piece forged wheel with five straight spokes and, between them, five large hexagonal openings, each with its own frame. The spokes cross the ring of bolts and reach the edge of the lip. These bolts, recessed and discreet, join the centre to a deep lip. On a chrome lip, the centre is in brushed bronze or brushed silver; on a gloss black lip, a centre in brushed gold or brushed anthracite grey stands out more.
Offered from 18″ to 24″. From 20″, its large hexagonal openings show at full scale, on an SUV or a large saloon alike.
How to order

For Great Britain, our checkout charges in pounds sterling. It converts the euro price at its exchange rate on the day, currency conversion charge included, so the amount in pounds is about 2% more than a straight conversion at the market rate; the amount shown at checkout is the one charged for your order. The amounts in pounds on this page are those of 4 October 2026. Delivery is included in the price, so UK import VAT (20%) applies to the whole amount in pounds. An 18″ set came to £3,735 at checkout (€4,300 on this website), or £4,482 with UK import VAT. The carrier collects the VAT before delivery, together with its clearance fee (for example, DHL Express charges £11 or 2.5% of the duty and VAT it pays, whichever is higher) and any import duty. Any import duty depends on the UK tariff in force when your wheels arrive: the amount you pay is the one on the carrier's notice, and UK import VAT then applies to it too. The details are on our Delivery to Great Britain page.

Engineering and specifications
- Material: forged 6061-T6 aluminium; forging closes up the porosity that a cast wheel can retain.
- Construction: two-piece, a forged centre and a separate barrel, both 5-axis CNC machined and joined by a ring of visible bolts around the centre. The same design can be studied as a monoblock or three-piece wheel, on quotation from customer service.
- Measurements: PCD (bolt pattern), offset (ET) and centre bore machined for your car, to the measurements the Onyx Forged design office submits to you before machining; no spacers or spigot rings to add. The depth of the lip is set by the choice of barrel.
- Standards: wheels designed to JWL/VIA standards.
- Packaging: set of four wheels.
