How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Ford SteetKa UK Winter Edition ships from the factory on a 4x108 bolt pattern with a 63.4mm center bore and a 16x6J ET35 wheel. Our flush reference for the Ford SteetKa UK Winter Edition is 16x7J ET30.; our maximum aggressive reference is 17x7.5J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
Ford SteetKa UK Winter Edition OE Wheel Specs
The Ford SteetKa UK Winter Edition ships from the factory on 4x108 bolt pattern wheels with a 63.4mm center bore. The stock wheel size is 16x6J ET35, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ford SteetKa UK Winter Edition (2003) we drill the 4x108 pattern and cut the centre bore to 63.4mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 16x6J | ET35 | 4.88 in (124 mm) | — | — |
| Flush | 16x7J | ET30 | 5.18 in (132 mm) | +8 mm | +18 mm |
| Maximum | 17x7.5J | ET25 | 5.23 in (133 mm) | +9 mm | +29 mm |
Vehicles With the Same Hub as the Ford SteetKa UK Winter Edition (4x108, 63.4 mm Bore)
In our database, 33 other vehicle entries from 4 makes use exactly the same 4x108 bolt pattern and 63.4 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
4x108 is used by 2.6% of the vehicle pages in our English fitment guide (171 of 6,503); 19.9% of those also use a 63.4 mm center bore.
Hub-Centric Rings for a 63.4 mm Center Bore
A wheel with a center bore larger than 63.4 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 64.1 mm | 64.1 → 63.4 mm |
| 65.1 mm | 65.1 → 63.4 mm |
| 66.1 mm | 66.1 → 63.4 mm |
| 66.6 mm | 66.6 → 63.4 mm |
| 73.1 mm | 73.1 → 63.4 mm |
ANKUSI forged wheels are bored to exactly 63.4 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Ford SteetKa UK Winter Edition use?
The 2003 Ford SteetKa UK Winter Edition uses a 4x108 bolt pattern.
How many lug bolts does the Ford SteetKa UK Winter Edition use?
The Ford SteetKa UK Winter Edition uses a 4-lug bolt pattern (4x108), so you need a 4-lug forged wheel to bolt straight on.
What is the center bore size on the Ford SteetKa UK Winter Edition?
The Ford SteetKa UK Winter Edition's center bore is 63.4mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Ford SteetKa UK Winter Edition?
Factory wheels on the Ford SteetKa UK Winter Edition are 16x6J ET35.
What does a flush wheel fitment look like on the Ford SteetKa UK Winter Edition?
For a flush look with minimal to no rubbing, we recommend 16x7J at ET30 offset as a starting point on a stock or mildly lowered Ford SteetKa UK Winter Edition.
Do I need wheel spacers for my Ford SteetKa UK Winter Edition?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my Ford SteetKa UK Winter Edition?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 5.18" of backspacing.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Ford SteetKa UK Winter Edition?
The Ford SteetKa UK Winter Edition runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 136 Nm (100 ft-lb). Covers most Ford passenger cars and crossovers (Fusion, Focus, Escape and similar) on M12x1.5 studs.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
