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
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Ford Focus Coupe-Cabriolet ships from the factory on a 4x108 bolt pattern with a 63.4mm center bore and a 17x7J ET52.5 wheel. Our flush reference for the Ford Focus Coupe-Cabriolet is 18x8J ET38.; our maximum aggressive reference is 18x8.5J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
Ford Focus Coupe-Cabriolet OE Wheel Specs
The Ford Focus Coupe-Cabriolet ships from the factory on 4x108 bolt pattern wheels with a 63.4mm center bore. The stock wheel size is 17x7J ET52.5, 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 Focus Coupe-Cabriolet (2008) 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
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) | 17x7J | ET52.5 | 6.07 in (154 mm) | — | — |
| Flush | 18x8J | ET38 | 6.00 in (152 mm) | −2 mm | +27 mm |
| Maximum | 18x8.5J | ET35 | 6.13 in (156 mm) | +2 mm | +37 mm |
Vehicles With the Same Hub as the Ford Focus Coupe-Cabriolet (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 Focus Coupe-Cabriolet use?
The 2008 Ford Focus Coupe-Cabriolet uses a 4x108 bolt pattern.
How many lug bolts does the Ford Focus Coupe-Cabriolet use?
The Ford Focus Coupe-Cabriolet 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 Focus Coupe-Cabriolet?
The Ford Focus Coupe-Cabriolet'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 Focus Coupe-Cabriolet?
Factory wheels on the Ford Focus Coupe-Cabriolet are 17x7J ET52.5.
What does a flush wheel fitment look like on the Ford Focus Coupe-Cabriolet?
For a flush look with minimal to no rubbing, we recommend 18x8J at ET38 offset as a starting point on a stock or mildly lowered Ford Focus Coupe-Cabriolet.
Do I need wheel spacers for my Ford Focus Coupe-Cabriolet?
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 Focus Coupe-Cabriolet?
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 6" 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 Focus Coupe-Cabriolet?
The Ford Focus Coupe-Cabriolet 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: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
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.
