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 SVT Mustang Cobra MystiChrome runs a 5x114.3 bolt pattern, 70.5mm center bore, and a F: 17x9.0J wheel from the factory. Our Flush Fitment reference is F 18x9.5J ET25 / R 18x10.5J ET25, which tucks the tire under the fender lip on a stock-height Ford SVT Mustang Cobra MystiChrome. Our Maximum Aggressive reference is F 18x10.0J ET20 / R 18x11.0J ET20 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ford SVT Mustang Cobra MystiChrome OE Wheel Specs
The 2004 Ford SVT Mustang Cobra MystiChrome (Coupe) uses a 5x114.3 bolt pattern with a 70.5mm center bore. Factory wheels are F: 17x9.0J R: 17x9.0J.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ford SVT Mustang Cobra MystiChrome (2004) 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.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 17x9.0J ET30 → ~6.18″ F backspacing, R 17x9.0J ET30 → ~6.18″ R backspacing
- Flush: F 18x9.5J ET25 → ~6.23″ F backspacing, R 18x10.5J ET25 → ~6.73″ R backspacing
- Max: F 18x10.0J ET20 → ~6.29″ F backspacing, R 18x11.0J ET20 → ~6.79″ R 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 SVT Mustang Cobra MystiChrome? 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 SVT Mustang Cobra MystiChrome (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 SVT Mustang Cobra MystiChrome use?
The 2004 Ford SVT Mustang Cobra MystiChrome uses a 5x114.3 bolt pattern.
How many lug bolts does the Ford SVT Mustang Cobra MystiChrome use?
The Ford SVT Mustang Cobra MystiChrome 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 SVT Mustang Cobra MystiChrome?
The Ford SVT Mustang Cobra MystiChrome'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 SVT Mustang Cobra MystiChrome?
Factory wheels on the Ford SVT Mustang Cobra MystiChrome are F: 17x9.0J R: 17x9.0J.
What is the biggest wheel size I can fit on my Ford SVT Mustang Cobra MystiChrome without rubbing?
The most aggressive fitment we recommend without fender work is F 18x10.0J ET20 / R 18x11.0J ET20. 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 SVT Mustang Cobra MystiChrome?
For a flush look with minimal to no rubbing, we recommend F 18x9.5J ET25 / R 18x10.5J ET25 as a starting point on a stock or mildly lowered Ford SVT Mustang Cobra MystiChrome.
Do I need wheel spacers for my Ford SVT Mustang Cobra MystiChrome?
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 SVT Mustang Cobra MystiChrome?
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 6.23" backspacing up front and 6.73" in the rear.
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 SVT Mustang Cobra MystiChrome?
Yes — the Ford SVT Mustang Cobra MystiChrome's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
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.
