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 performance-oriented coupe, the wheel is one of the few components where shaving weight has a compounding effect — less rotational mass means less work for the brakes, the drivetrain, and the chassis on every input. A forged wheel gets there without compromising the strength margin the factory engineered in.

The Mansory Bel Air (Rolls-Royce Drophead Coupe) ships from the factory on a 5x120 bolt pattern with a 72.6mm center bore and a 22x10J ET25 wheel. Our flush reference for the Mansory Bel Air (Rolls-Royce Drophead Coupe) is 22x10.5J ET20.; our maximum aggressive reference is 24x10.5J ET15. — beyond that, expect clearance issues against the fender liner without further modification.

Mansory Bel Air (Rolls-Royce Drophead Coupe) OE Wheel Specs

The Mansory Bel Air (Rolls-Royce Drophead Coupe) ships from the factory on 5x120 bolt pattern wheels with a 72.6mm center bore. The stock wheel size is 22x10J 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 Mansory Bel Air (Rolls-Royce Drophead Coupe) (2008) we drill the 5x120 pattern and cut the centre bore to 72.6mm 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.

Vehicles With the Same Hub as the Mansory Bel Air (Rolls-Royce Drophead Coupe) (5x120, 72.6 mm Bore)

In our database, 338 other vehicle entries from 10 makes use exactly the same 5x120 bolt pattern and 72.6 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.

5x120 is used by 10.3% of the vehicle pages in our English fitment guide (670 of 6,503); 50.6% of those also use a 72.6 mm center bore.

Hub-Centric Rings for a 72.6 mm Center Bore

A wheel with a center bore larger than 72.6 mm needs a hub-centric ring. The most common combinations:

Wheel boreRing size
73.1 mm73.1 → 72.6 mm
74.1 mm74.1 → 72.6 mm
76.1 mm76.1 → 72.6 mm
78.1 mm78.1 → 72.6 mm

ANKUSI forged wheels are bored to exactly 72.6 mm for this vehicle, so no ring is needed.

Frequently Asked Questions

What bolt pattern (PCD) does the Mansory Bel Air (Rolls-Royce Drophead Coupe) use?
The 2008 Mansory Bel Air (Rolls-Royce Drophead Coupe) uses a 5x120 bolt pattern.
How many lug bolts does the Mansory Bel Air (Rolls-Royce Drophead Coupe) use?
The Mansory Bel Air (Rolls-Royce Drophead Coupe) uses a 5-lug bolt pattern (5x120), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Mansory Bel Air (Rolls-Royce Drophead Coupe)?
The Mansory Bel Air (Rolls-Royce Drophead Coupe)'s center bore is 72.6mm. 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 size are the factory (stock) wheels on the Mansory Bel Air (Rolls-Royce Drophead Coupe)?
Factory wheels on the Mansory Bel Air (Rolls-Royce Drophead Coupe) are 22x10J ET25.
What does a flush wheel fitment look like on the Mansory Bel Air (Rolls-Royce Drophead Coupe)?
For a flush look with minimal to no rubbing, we recommend 22x10.5J at ET20 offset as a starting point on a stock or mildly lowered Mansory Bel Air (Rolls-Royce Drophead Coupe).
Do I need wheel spacers for my Mansory Bel Air (Rolls-Royce Drophead 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 Mansory Bel Air (Rolls-Royce Drophead 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 6.54" of backspacing.
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 Mansory Bel Air (Rolls-Royce Drophead Coupe)?
The Mansory Bel Air (Rolls-Royce Drophead Coupe) runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
