Forged Wheel
XYZ Forged OS-27
SKU: XYZ-WHL-OS-27
Understanding wheel fitment
Diameter × width
Diameter is the measurement across the face of the wheel in inches. Width is the distance between the inner and outer bead seats. Wider wheels need wider tyres and may require fender rolling or spacers.
PCD (bolt pattern)
PCD (Pitch Circle Diameter) is the number of bolts × bolt-circle diameter in mm. Example: 5×114.3 means 5 bolts on a 114.3mm circle. This MUST match your hub exactly — no adaptors are supplied.
Offset (ET)
Offset (ET) is how far the mounting face sits from the centre line, in mm. Higher (positive) numbers tuck the wheel in; lower (or negative) numbers push it out. A wheel that is 1–3mm off stock offset can still fit; more than that and you will need arch work.
Centre bore
Centre bore is the diameter of the central hole in millimetres. It must equal or exceed your hub bore. Smaller = will not fit. Larger = use hub-centric rings (included free on request).
Load rating
Load rating is the maximum kg each wheel is rated to carry. Confirm your vehicle axle weight (GVW ÷ 2) is below this figure. All XYZ Racing forged wheels exceed OEM factory ratings.

About this design
Five primary spokes fork into broad twin blades in a clean Y-split across a moderately concave machined face behind a polished stepped outer lip. A refined balanced split-five with genuine forged muscle — purposeful enough for a track-prepared car, premium enough for a properly built GT or touring build.
OS Series
Deep dish, architectural faces
The OS is a depth-first series with an unusually wide spread of faces. Every design shares a deeply concave face set behind a wide, prominent barrel, but the spoke work ranges from open five-spokes and forked Y-spokes to intricate crosshatch mesh and architectural lattice patterns. The outer lip stays clean throughout — no exposed hardware — so the focus is on the contrast between the recessed face and the bold barrel. The open faces aren't only for show: they clear and cool a big brake package well. It suits wide fitment and stance builds that want genuine depth and presence.
Forged to order — built for one car: yours
Every XYZ forged wheel is made to order. Beyond the offset (ET), width (J) and bolt pattern, you can commission a completely bespoke design and colour — down to a single wheel if that's all you need. This is genuine one-off manufacturing, not a fixed catalogue.
Engineered, then tested to destruction
Once your order is placed, the design is run through stress-analysis software to verify its structural safety factor. Then we prove it physically: for every customer's vehicle we build additional wheels and fit a brand-new tyre purely for destructive mechanical testing to VIA / JWL and TÜV standards —
- Dynamic Radial Fatigue Test
- Dynamic Cornering Fatigue Test
- Impact Test
A wheel is only released once it has passed both the computer analysis and the physical destructive testing and met every applicable safety standard. Completing the programme takes six wheels per vehicle — it costs more than mass-produced wheels, and that is exactly the point. Three official VIA / JWL test reports are included in the box.
Made for people who love their cars
If you want something genuinely one-of-a-kind — a bespoke design, a unique colour, or a forged wheel inspired by the supercars you grew up with, built to fit your car — this is where you start. We are one of very few manufacturers in the world that will take a single-piece, fully custom wheel design and put it through the full safety programme above. And if your car runs air suspension and tucks deep into the arches when parked, these wheels were made for that stance.
Good to know before you order
- Custom width (J) and offset (ET): no extra charge.
- Bespoke designs welcome (priced on the design). 3D curved-surface and left/right directional designs carry a small per-wheel charge.
- Over 20,000 PPG / Axalta colours, two-tone finishes and custom centre-cap logos supported.
- VIA / JWL certification is included free on every current design.
- Minimum order is two wheels of the same size and colour.
- Website images are a guide only — every wheel is built from a final 2D drawing that you approve and sign.
