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
A convertible carries its extra structural weight low and behind the axle line, so wheel mass and offset changes show up in ride and steering feel faster than they do on the coupe. A forged wheel keeps the rotating mass down while you add the width the arches will take.
The Porsche 911 Targa 4 runs a 5x130 fitment, 71.6mm center bore, and a F: 19x8J wheel from the factory. Our Flush Fitment reference is F 19x8.5J ET47 / R 19x11J ET45, which tucks the tire under the fender lip on a stock-height Porsche 911 Targa 4. Our Maximum Aggressive reference is F 19x9J ET47 / R 19x12J ET46 - beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Porsche 911 Targa 4 OE Wheel Specs
The 2009 Porsche 911 Targa 4 (Sports Convertible) uses a 5x130 bolt pattern with a 71.6mm center bore. Factory wheels are F: 19x8J R: 19x11J.
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 Targa 4 (2009) 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.

Flush Fitment
For a flush look with minimal rubbing, F 19x8.5J ET47 / R 19x11J ET45 is the recommended starting point on a stock or mildly lowered Porsche 911 Targa 4.
Maximum Aggressive Fitment
F 19x9J ET47 / R 19x12J ET46 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 19x8J ET51 → ~6.51″ F backspacing, R 19x11J ET51 → ~8.01″ R backspacing
- Flush: F 19x8.5J ET47 → ~6.6″ F backspacing, R 19x11J ET45 → ~7.77″ R backspacing
- Max: F 19x9J ET47 → ~6.85″ F backspacing, R 19x12J ET46 → ~8.31″ 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 Targa 4? 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 Targa 4 (2009)
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, so the 5x130 pattern and the 71.6mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
Designs we already tool for the 5x130 pattern — each one is re-cut to your sizes and offsets:

What bolt pattern (PCD) does the Porsche 911 Targa 4 use?
The 2009 Porsche 911 Targa 4 uses a 5x130 bolt pattern.
How many lug bolts does the Porsche 911 Targa 4 use?
The Porsche 911 Targa 4 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 Targa 4?
The Porsche 911 Targa 4'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 Targa 4?
Factory wheels on the Porsche 911 Targa 4 are F: 19x8J R: 19x11J.
What is the biggest wheel size I can fit on my Porsche 911 Targa 4 without rubbing?
The most aggressive fitment we recommend without fender work is F 19x9J ET47 / R 19x12J ET46. 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 Targa 4?
For a flush look with minimal to no rubbing, we recommend F 19x8.5J ET47 / R 19x11J ET45 as a starting point on a stock or mildly lowered Porsche 911 Targa 4.
Do I need wheel spacers for my Porsche 911 Targa 4?
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 Targa 4?
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 6.6" backspacing up front and 7.77" 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 Targa 4?
Yes — the Porsche 911 Targa 4'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.
