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 Porsche 911 2.0 Coupe runs a 5x130 fitment, 71.6mm center bore, and a F: 15x4.5J wheel from the factory. Our Flush Fitment reference is F 15x6J ET36 / R 15x7J ET23, which tucks the tire under the fender lip on a stock-height Porsche 911 2.0 Coupe. Our Maximum Aggressive reference is F 15x6J ET36 / R 15x7J ET23 - the verified data does not support going wider than the flush spec on this chassis.
Porsche 911 2.0 Coupe OE Wheel Specs
The 1964 Porsche 911 2.0 Coupe (Sports Coupe) uses a 5x130 bolt pattern with a 71.6mm center bore. Factory wheels are 15x4.5J F/R.
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
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Porsche 911 2.0 Coupe (1964) we drill the 5x130 pattern and cut the centre bore to 71.6mm 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.

Real-World Fitment Notes
Early short-wheelbase 911s run 15in Fuchs (5.5-7J) or Braid reproductions; hot-rod builds go 15x9 rear with 225/50 5x130 / 71.6 CB; short-wheelbase cars are fender-tight, confirm clearance before wide rears
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 15x4.5J ET45 → ~4.52″ F backspacing, R 15x4.5J ET45 → ~4.52″ R backspacing
- Flush: F 15x6J ET36 → ~4.92″ F backspacing, R 15x7J ET23 → ~4.91″ R backspacing
- Max: F 15x6J ET36 → ~4.92″ F backspacing, R 15x7J ET23 → ~4.91″ 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 911 2.0 Coupe? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Frequently Asked Questions
What bolt pattern (PCD) does the Porsche 911 2.0 Coupe use?
The 1964 Porsche 911 2.0 Coupe uses a 5x130 bolt pattern.
How many lug bolts does the Porsche 911 2.0 Coupe use?
The Porsche 911 2.0 Coupe uses a 5-lug bolt pattern (5x130), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Porsche 911 2.0 Coupe?
The Porsche 911 2.0 Coupe's center bore is 71.6mm. 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 Porsche 911 2.0 Coupe?
Factory wheels on the Porsche 911 2.0 Coupe are 15x4.5J F/R.
What is the biggest wheel size I can fit on my Porsche 911 2.0 Coupe without rubbing?
The most aggressive fitment we recommend without fender work is F 15x6J ET36 / R 15x7J ET23. 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 Porsche 911 2.0 Coupe?
For a flush look with minimal to no rubbing, we recommend F 15x6J ET36 / R 15x7J ET23 as a starting point on a stock or mildly lowered Porsche 911 2.0 Coupe.
Do I need wheel spacers for my Porsche 911 2.0 Coupe?
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 Porsche 911 2.0 Coupe?
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 4.92" backspacing up front and 4.91" 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 Porsche 911 2.0 Coupe?
Yes — the Porsche 911 2.0 Coupe'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.
