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
At this power level the wheel is a safety component. Offsets are tight, brake packages are enormous, and there is very little room between the caliper and the barrel. A forged wheel built to the correct spec is not a cosmetic upgrade here - it is the only sensible way to change the look without compromising clearance or strength.
The Porsche 911 Carrera GTS runs a Centerlock fitment, 71.6mm center bore, and a F: 20x8.5J wheel from the factory. Our Flush Fitment reference is F 20x9.5J ET44 / R 21x12J ET66, which tucks the tire under the fender lip on a stock-height Porsche 911 Carrera GTS. Our Maximum Aggressive reference is F 20x9.5J ET44 / R 21x12J ET66 - the verified data does not support going wider than the flush spec on this chassis.
Porsche 911 Carrera GTS OE Wheel Specs
The 2022 Porsche 911 Carrera GTS (Supercar) runs a Centerlock hub with a 71.6mm register. Factory wheels are F: 20x8.5J R: 21x11.5J.
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 Carrera GTS (2022) we machine every wheel to the vehicle’s own hub dimensions 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.

Flush Fitment
For a flush look with minimal rubbing, F 20x9.5J ET44 / R 21x12J ET66 is the recommended starting point on a stock or mildly lowered Porsche 911 Carrera GTS.
Maximum Aggressive Fitment
F 20x9.5J ET44 / R 21x12J ET66 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 20x8.5J ET50 → ~6.72″ F backspacing, R 21x11.5J ET66 → ~8.85″ R backspacing
- Flush: F 20x9.5J ET44 → ~6.98″ F backspacing, R 21x12J ET66 → ~9.1″ R backspacing
- Max: F 20x9.5J ET44 → ~6.98″ F backspacing, R 21x12J ET66 → ~9.1″ 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 Carrera GTS? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Porsche 911 Carrera GTS (2022)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
We do not hold this pattern wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.
Frequently Asked Questions
What is the biggest wheel size I can fit on my Porsche 911 Carrera GTS without rubbing?
The most aggressive fitment we recommend without fender work is F 20x9.5J ET44 / R 21x12J ET66. 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 Carrera GTS?
For a flush look with minimal to no rubbing, we recommend F 20x9.5J ET44 / R 21x12J ET66 as a starting point on a stock or mildly lowered Porsche 911 Carrera GTS.
Do I need wheel spacers for my Porsche 911 Carrera GTS?
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 Carrera GTS?
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 6.98" backspacing up front and 9.1" 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 Carrera GTS?
Yes — the Porsche 911 Carrera GTS'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.
