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 supercar, wheel weight is one of the few remaining places to cut rotational mass without touching the powertrain or chassis the factory already optimized. Forging gets there at the same structural margin as the OE wheel, which is exactly the trade a car built around outright performance rewards.
The TechArt Porsche 911 Turbo Cabriolet ships from the factory on a 5x130 bolt pattern with a 71.6mm center bore and a F 19x8.5J ET56 / R 19x11J ET51 wheel. Our flush reference for the TechArt Porsche 911 Turbo Cabriolet is F 20x9J ET42 / R 20x12J ET45.; our maximum aggressive reference is F 20x9.5J ET38 / R 20x12.5J ET40. — beyond that, expect clearance issues against the fender liner without further modification.
TechArt Porsche 911 Turbo Cabriolet OE Wheel Specs
The TechArt Porsche 911 Turbo Cabriolet ships from the factory on 5x130 bolt pattern wheels with a 71.6mm center bore. The stock wheel size is F 19x8.5J ET56 / R 19x11J ET51, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the TechArt Porsche 911 Turbo Cabriolet (2007) 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.

Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 19x8.5J | ET56 | 6.95 in (177 mm) | — | — |
| Flush | 20x9J | ET42 | 6.65 in (169 mm) | −8 mm | +20 mm |
| Maximum | 20x9.5J | ET38 | 6.75 in (171 mm) | −5 mm | +31 mm |
Vehicles With the Same Hub as the TechArt Porsche 911 Turbo Cabriolet (5x130, 71.6 mm Bore)
In our database, 294 other vehicle entries from 10 makes use exactly the same 5x130 bolt pattern and 71.6 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x130 is used by 5.8% of the vehicle pages in our English fitment guide (375 of 6,503); 78.7% of those also use a 71.6 mm center bore.
Hub-Centric Rings for a 71.6 mm Center Bore
A wheel with a center bore larger than 71.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 72.6 mm | 72.6 → 71.6 mm |
| 73.1 mm | 73.1 → 71.6 mm |
| 74.1 mm | 74.1 → 71.6 mm |
| 76.1 mm | 76.1 → 71.6 mm |
ANKUSI forged wheels are bored to exactly 71.6 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the TechArt Porsche 911 Turbo Cabriolet use?
The 2007 TechArt Porsche 911 Turbo Cabriolet uses a 5x130 bolt pattern.
How many lug bolts does the TechArt Porsche 911 Turbo Cabriolet use?
The TechArt Porsche 911 Turbo Cabriolet 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 TechArt Porsche 911 Turbo Cabriolet?
The TechArt Porsche 911 Turbo Cabriolet'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 does a flush wheel fitment look like on the TechArt Porsche 911 Turbo Cabriolet?
For a flush look with minimal to no rubbing, we recommend F 20x9J ET42 / R 20x12J ET45 as a starting point on a stock or mildly lowered TechArt Porsche 911 Turbo Cabriolet.
Do I need wheel spacers for my TechArt Porsche 911 Turbo Cabriolet?
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 TechArt Porsche 911 Turbo Cabriolet?
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 6.65" backspacing up front and 8.27" 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 TechArt Porsche 911 Turbo Cabriolet?
Yes — the TechArt Porsche 911 Turbo Cabriolet'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.
