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 sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Maserati GranSport ships from the factory on a 5x108 bolt pattern with a 67.1mm center bore and a F 19x8J ET52 / R 19x9.5J ET50 wheel. Our flush reference for the Maserati GranSport is F 19x8.5J ET42 / R 19x10J ET40.; our maximum aggressive reference is F 20x9J ET38 / R 20x10.5J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
Maserati GranSport OE Wheel Specs
The Maserati GranSport ships from the factory on 5x108 bolt pattern wheels with a 67.1mm center bore. The stock wheel size is F 19x8J ET52 / R 19x9.5J ET50, 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 Maserati GranSport (2004) we drill the 5x108 pattern and cut the centre bore to 67.1mm 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) | 19x8J | ET52 | 6.55 in (166 mm) | — | — |
| Flush | 19x8.5J | ET42 | 6.40 in (163 mm) | −4 mm | +16 mm |
| Maximum | 20x9J | ET38 | 6.50 in (165 mm) | −1 mm | +27 mm |
Vehicles With the Same Hub as the Maserati GranSport (5x108, 67.1 mm Bore)
In our database, 33 other vehicle entries from 5 makes use exactly the same 5x108 bolt pattern and 67.1 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.
5x108 is used by 7.7% of the vehicle pages in our English fitment guide (499 of 6,503); 6.8% of those also use a 67.1 mm center bore.
Hub-Centric Rings for a 67.1 mm Center Bore
A wheel with a center bore larger than 67.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.1 mm | 70.1 → 67.1 mm |
| 70.5 mm | 70.5 → 67.1 mm |
| 71.6 mm | 71.6 → 67.1 mm |
| 72.6 mm | 72.6 → 67.1 mm |
| 73.1 mm | 73.1 → 67.1 mm |
ANKUSI forged wheels are bored to exactly 67.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Maserati GranSport use?
The 2004 Maserati GranSport uses a 5x108 bolt pattern.
How many lug bolts does the Maserati GranSport use?
The Maserati GranSport uses a 5-lug bolt pattern (5x108), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Maserati GranSport?
The Maserati GranSport's center bore is 67.1mm. 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 Maserati GranSport?
For a flush look with minimal to no rubbing, we recommend F 19x8.5J ET42 / R 19x10J ET40 as a starting point on a stock or mildly lowered Maserati GranSport.
Do I need wheel spacers for my Maserati GranSport?
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 Maserati GranSport?
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 6.4" backspacing up front and 7.07" 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 Maserati GranSport?
Yes — the Maserati GranSport'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.
