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
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Infiniti G35 Sport Coupe runs a 5x114.3 bolt pattern, 66.1mm center bore, and a F: 18x8J wheel from the factory. Our Flush Fitment reference is F 19x9.5J ET22 / R 19x10.5J ET22, which tucks the tire under the fender lip on a stock-height Infiniti G35 Sport Coupe. Our Maximum Aggressive reference is F 19x10J ET15 / R 19x11J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Infiniti G35 Sport Coupe OE Wheel Specs
The 2006 Infiniti G35 Sport Coupe (Coupe) uses a 5x114.3 bolt pattern with a 66.1mm center bore. Factory wheels are F: 18x8J R: 18x8J.
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 Infiniti G35 Sport Coupe (2006) 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.

Real-World Fitment Notes
Chassis: Coilovers. Brakes: Brembo 4-piston calipers require high-disk face. Tires: 225/45 R18 F, 245/45 R18 R.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 18x8J ET30 → ~5.68″ F backspacing, R 18x8J ET33 → ~5.8″ R backspacing
- Flush: F 19x9.5J ET22 → ~6.12″ F backspacing, R 19x10.5J ET22 → ~6.62″ R backspacing
- Max: F 19x10J ET15 → ~6.09″ F backspacing, R 19x11J ET15 → ~6.59″ 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 Infiniti spec, or want a wheel built to a custom offset for your Infiniti G35 Sport Coupe? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Infiniti G35 Sport Coupe: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 2003 | 5x114.3 | 66.1 mm | 17x7.5J |
| 2006 | 5x114.3 | 66.1 mm | 18x8J |
Bolt pattern and center bore stay the same across all 2 model years in our database (2003–2006).
Vehicles With the Same Hub as the Infiniti G35 Sport Coupe (5x114.3, 66.1 mm Bore)
In our database, 223 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 Infiniti G35 Sport Coupe use?
The 2006 Infiniti G35 Sport Coupe uses a 5x114.3 bolt pattern.
How many lug bolts does the Infiniti G35 Sport Coupe use?
The Infiniti G35 Sport Coupe 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 Infiniti G35 Sport Coupe?
The Infiniti G35 Sport Coupe'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 size are the factory (stock) wheels on the Infiniti G35 Sport Coupe?
Factory wheels on the Infiniti G35 Sport Coupe are F: 18x8J R: 18x8J.
What is the biggest wheel size I can fit on my Infiniti G35 Sport Coupe without rubbing?
The most aggressive fitment we recommend without fender work is F 19x10J ET15 / R 19x11J ET15. 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 Infiniti G35 Sport Coupe?
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 Infiniti G35 Sport Coupe.
Do I need wheel spacers for my Infiniti G35 Sport Coupe?
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 Infiniti G35 Sport Coupe?
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 Infiniti G35 Sport Coupe?
Yes — the Infiniti G35 Sport Coupe'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.
