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
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Nissan 350Z Roadster EUR ships from the factory on a 5x114.3 bolt pattern with a 66.1mm center bore and a F 18x8J ET30 / R 18x8.5J ET33 wheel. Our flush reference for the Nissan 350Z Roadster EUR is F 19x9.5J ET22 / R 19x10.5J ET22.; our maximum aggressive reference is F 19x10J ET15 / R 19x11J ET15. — beyond that, expect clearance issues against the fender liner without further modification.
Nissan 350Z Roadster EUR OE Wheel Specs
The Nissan 350Z Roadster EUR ships from the factory on 5x114.3 bolt pattern wheels with a 66.1mm center bore. The stock wheel size is F 18x8J ET30 / R 18x8.5J ET33, 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 Nissan 350Z Roadster EUR (2005) we drill the 5x114.3 pattern and cut the centre bore to 66.1mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
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) | 18x8J | ET30 | 5.68 in (144 mm) | — | — |
| Flush | 19x9.5J | ET22 | 6.12 in (155 mm) | +11 mm | +27 mm |
| Maximum | 19x10J | ET15 | 6.09 in (155 mm) | +10 mm | +40 mm |
Vehicles With the Same Hub as the Nissan 350Z Roadster EUR (5x114.3, 66.1 mm Bore)
In our database, 224 other vehicle entries from 9 makes use exactly the same 5x114.3 bolt pattern and 66.1 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.
5x114.3 is used by 20.0% of the vehicle pages in our English fitment guide (1,300 of 6,503); 17.3% of those also use a 66.1 mm center bore.
Hub-Centric Rings for a 66.1 mm Center Bore
A wheel with a center bore larger than 66.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.6 mm | 66.6 → 66.1 mm |
| 67.1 mm | 67.1 → 66.1 mm |
| 70.1 mm | 70.1 → 66.1 mm |
| 70.5 mm | 70.5 → 66.1 mm |
| 73.1 mm | 73.1 → 66.1 mm |
ANKUSI forged wheels are bored to exactly 66.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Nissan 350Z Roadster EUR use?
The 2005 Nissan 350Z Roadster EUR uses a 5x114.3 bolt pattern.
How many lug bolts does the Nissan 350Z Roadster EUR use?
The Nissan 350Z Roadster EUR uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Nissan 350Z Roadster EUR?
The Nissan 350Z Roadster EUR's center bore is 66.1mm. 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 Nissan 350Z Roadster EUR?
For a flush look with minimal to no rubbing, we recommend F 19x9.5J ET22 / R 19x10.5J ET22 as a starting point on a stock or mildly lowered Nissan 350Z Roadster EUR.
Do I need wheel spacers for my Nissan 350Z Roadster EUR?
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 Nissan 350Z Roadster EUR?
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 6.12" backspacing up front and 6.62" 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 Nissan 350Z Roadster EUR?
Yes — the Nissan 350Z Roadster EUR'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.
Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.25, conical-seat lug nut.
Factory Torque Spec: 103-122 Nm (76-90 ft-lb). Range covers most Nissan passenger cars and crossovers on M12x1.25 studs.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
