Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |

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
With less structural stiffness from the missing roof, a convertible's suspension tuning leans more heavily on unsprung mass control. Forged construction keeps wheel weight down at the same strength rating, which is one less variable working against the Ford Mustang GT Convertible's chassis.
The Ford Mustang GT Convertible runs a 5x114.3 bolt pattern, 70.5mm center bore, and a 17x8.0J, 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 GT Convertible. 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 GT Convertible OE Wheel Specs
The 2001 Ford Mustang GT Convertible (Convertible) uses a 5x114.3 bolt pattern with a 70.5mm center bore. Factory wheels are 17x8.0J 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
Flush Fitment
For a flush look with minimal rubbing, F/R 19x9.0J ET38 is the recommended starting point on a stock or mildly lowered Ford Mustang GT Convertible.
Maximum Aggressive Fitment
F/R 20x9.5J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x8.0J 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 GT Convertible? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

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.
