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 Nismo Nissan Skyline R34 GTR Z Tune ships from the factory on a 5x114.3 bolt pattern with a 66.1mm center bore and a F 18x10J ET25 / R 18x10J ET25 wheel. Our flush reference for the Nismo Nissan Skyline R34 GTR Z Tune is F 18x10.5J ET18 / R 18x10.5J ET18.; our maximum aggressive reference is F 18x11J ET15 / R 18x11J ET15. — beyond that, expect clearance issues against the fender liner without further modification.
Nismo Nissan Skyline R34 GTR Z Tune OE Wheel Specs
The Nismo Nissan Skyline R34 GTR Z Tune ships from the factory on 5x114.3 bolt pattern wheels with a 66.1mm center bore. The stock wheel size is F 18x10J ET25 / R 18x10J ET25, 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 Nismo Nissan Skyline R34 GTR Z Tune (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) | 18x10J | ET25 | 6.48 in (165 mm) | — | — |
| Flush | 18x10.5J | ET18 | 6.46 in (164 mm) | −1 mm | +13 mm |
| Maximum | 18x11J | ET15 | 6.59 in (167 mm) | +3 mm | +23 mm |
Vehicles With the Same Hub as the Nismo Nissan Skyline R34 GTR Z Tune (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 Nismo Nissan Skyline R34 GTR Z Tune use?
The 2005 Nismo Nissan Skyline R34 GTR Z Tune uses a 5x114.3 bolt pattern.
How many lug bolts does the Nismo Nissan Skyline R34 GTR Z Tune use?
The Nismo Nissan Skyline R34 GTR Z Tune 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 Nismo Nissan Skyline R34 GTR Z Tune?
The Nismo Nissan Skyline R34 GTR Z Tune'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 Nismo Nissan Skyline R34 GTR Z Tune?
For a flush look with minimal to no rubbing, we recommend F 18x10.5J ET18 / R 18x10.5J ET18 as a starting point on a stock or mildly lowered Nismo Nissan Skyline R34 GTR Z Tune.
Do I need wheel spacers for my Nismo Nissan Skyline R34 GTR Z Tune?
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 Nismo Nissan Skyline R34 GTR Z Tune?
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 6.46" backspacing up front and 6.46" 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 Nismo Nissan Skyline R34 GTR Z Tune?
Yes — the Nismo Nissan Skyline R34 GTR Z Tune'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.
