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
On a performance-oriented coupe, the wheel is one of the few components where shaving weight has a compounding effect — less rotational mass means less work for the brakes, the drivetrain, and the chassis on every input. A forged wheel gets there without compromising the strength margin the factory engineered in.
The Ford Mustang Glass Roof runs a 5x114.3 bolt pattern, 70.5mm center bore, and a 18x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 19x9.0J ET38, which tucks the tire under the fender lip on a stock-height Ford Mustang Glass Roof. Our Maximum Aggressive reference is 20x9.5J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ford Mustang Glass Roof OE Wheel Specs
The 2009 Ford Mustang Glass Roof (Coupe) uses a 5x114.3 bolt pattern with a 70.5mm center bore. Factory wheels are 18x8.0J F/R.
Why the factory spec works for most owners:
- Preserves the factory-tuned ride and steering feel
- A mainstream size for this segment, keeping tire choice wide and prices reasonable
- Leaves full clearance for the stock brakes and suspension hardware
- Keeps handling predictable and consistent in everyday conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ford Mustang Glass Roof (2009) we drill the 5x114.3 pattern and cut the centre bore to 70.5mm 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.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x8.0J ET45 → ~6.27″ backspacing
- Flush: 19x9.0J ET38 → ~6.5″ backspacing
- Max: 20x9.5J ET35 → ~6.63″ backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Ford spec, or want a wheel built to a custom offset for your Ford Mustang Glass Roof? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Ford Mustang Glass Roof (5x114.3, 70.5 mm Bore)
In our database, 155 other vehicle entries from 6 makes use exactly the same 5x114.3 bolt pattern and 70.5 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.
5x114.3 is used by 20.0% of the vehicle pages in our English fitment guide (1,300 of 6,503); 12.0% of those also use a 70.5 mm center bore.
Hub-Centric Rings for a 70.5 mm Center Bore
A wheel with a center bore larger than 70.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 71.6 mm | 71.6 → 70.5 mm |
| 72.6 mm | 72.6 → 70.5 mm |
| 73.1 mm | 73.1 → 70.5 mm |
| 74.1 mm | 74.1 → 70.5 mm |
ANKUSI forged wheels are bored to exactly 70.5 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Ford Mustang Glass Roof use?
The 2009 Ford Mustang Glass Roof uses a 5x114.3 bolt pattern.
How many lug bolts does the Ford Mustang Glass Roof use?
The Ford Mustang Glass Roof uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Ford Mustang Glass Roof?
The Ford Mustang Glass Roof's center bore is 70.5mm. 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 Mustang Glass Roof?
Factory wheels on the Ford Mustang Glass Roof are 18x8.0J F/R.
What is the biggest wheel size I can fit on my Ford Mustang Glass Roof without rubbing?
The most aggressive fitment we recommend without fender work is 20x9.5J at ET35 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Ford Mustang Glass Roof?
For a flush look with minimal to no rubbing, we recommend 19x9.0J at ET38 offset as a starting point on a stock or mildly lowered Ford Mustang Glass Roof.
Do I need wheel spacers for my Ford Mustang Glass Roof?
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 Mustang Glass Roof?
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 6.5" 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 Mustang Glass Roof?
The Ford Mustang Glass Roof 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.
