Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | F: 15x6J R: 15x6J |

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 Porsche 944 runs a 5x130 bolt pattern, 71.6mm center bore, and a F: 15x6J wheel from the factory. Our Flush Fitment reference is F 16x7J ET40 / R 16x8J ET35, which tucks the tire under the fender lip on a stock-height Porsche 944. Our Maximum Aggressive reference is F 16x8J ET15 / R 16x8J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Porsche 944 OE Wheel Specs
The 1983 Porsche 944 (Sports Coupe) uses a 5x130 bolt pattern with a 71.6mm center bore. Factory wheels are F: 15x6J R: 15x6J.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
Flush Fitment
For a flush look with minimal rubbing, F 16x7J ET40 / R 16x8J ET35 is the recommended starting point on a stock or mildly lowered Porsche 944.
Maximum Aggressive Fitment
F 16x8J ET15 / R 16x8J ET15 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.
Real-World Fitment Notes
Unlike the visually similar 924, the 944 used the 5x130/71.6mm Porsche-hub pattern from launch. Base 944s share the 16-inch 'phone dial' wheel option (7J front, 8J rear) with the 924S; without the Turbo's flared rear quarters, most base 944 owners stay at 16 inches rather than pushing into the Turbo's 17-18 inch range.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 15x6J ET23 → ~4.41″ F backspacing, R 15x6J ET23 → ~4.41″ R backspacing
- Flush: F 16x7J ET40 → ~5.57″ F backspacing, R 16x8J ET35 → ~5.88″ R backspacing
- Max: F 16x8J ET15 → ~5.09″ F backspacing, R 16x8J ET15 → ~5.09″ R backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
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 Porsche spec, or want a wheel built to a custom offset for your Porsche 944? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
