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 Lotus Exige S 240 ships from the factory on a 4x100 bolt pattern with a 56.6mm center bore and a F 16x6.5J ET31 / R 17x8J ET38 wheel. Our flush reference for the Lotus Exige S 240 is F 16x7J ET25 / R 17x8.5J ET30.; our maximum aggressive reference is F 17x7.5J ET22 / R 18x9J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
Lotus Exige S 240 OE Wheel Specs
The Lotus Exige S 240 ships from the factory on 4x100 bolt pattern wheels with a 56.6mm center bore. The stock wheel size is F 16x6.5J ET31 / R 17x8J ET38, 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 Lotus Exige S 240 (2008) we drill the 4x100 pattern and cut the centre bore to 56.6mm 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.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 16x6.5J | ET31 | 4.97 in (126 mm) | — | — |
| Flush | 16x7J | ET25 | 4.98 in (127 mm) | 0 mm | +12 mm |
| Maximum | 17x7.5J | ET22 | 5.12 in (130 mm) | +4 mm | +22 mm |
Vehicles With the Same Hub as the Lotus Exige S 240 (4x100, 56.6 mm Bore)
In our database, 58 other vehicle entries from 7 makes use exactly the same 4x100 bolt pattern and 56.6 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.
4x100 is used by 6.9% of the vehicle pages in our English fitment guide (451 of 6,503); 13.1% of those also use a 56.6 mm center bore.
Hub-Centric Rings for a 56.6 mm Center Bore
A wheel with a center bore larger than 56.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 57.1 mm | 57.1 → 56.6 mm |
| 60.1 mm | 60.1 → 56.6 mm |
| 63.4 mm | 63.4 → 56.6 mm |
| 64.1 mm | 64.1 → 56.6 mm |
| 73.1 mm | 73.1 → 56.6 mm |
ANKUSI forged wheels are bored to exactly 56.6 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Lotus Exige S 240 use?
The 2008 Lotus Exige S 240 uses a 4x100 bolt pattern.
How many lug bolts does the Lotus Exige S 240 use?
The Lotus Exige S 240 uses a 4-lug bolt pattern (4x100), so you need a 4-lug forged wheel to bolt straight on.
What is the center bore size on the Lotus Exige S 240?
The Lotus Exige S 240's center bore is 56.6mm. 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 does a flush wheel fitment look like on the Lotus Exige S 240?
For a flush look with minimal to no rubbing, we recommend F 16x7J ET25 / R 17x8.5J ET30 as a starting point on a stock or mildly lowered Lotus Exige S 240.
Do I need wheel spacers for my Lotus Exige S 240?
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 Lotus Exige S 240?
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 4.98" backspacing up front and 5.93" 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 Lotus Exige S 240?
Yes — the Lotus Exige S 240'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.
