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
Hot hatches and performance compacts are built around quick direction changes, so rotational mass at the wheel has an outsized effect on how the car actually feels to drive. Forging trims that mass while holding the same strength margin as the factory wheel, which is exactly the trade-off this kind of platform rewards.
The Mini Cooper S John Cooper Works Tuning Kit runs a 4x100 bolt pattern, 56.1mm center bore, and a 17x7J at ET42, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8J ET38, which tucks the tire under the fender lip on a stock-height Mini Cooper S John Cooper Works Tuning Kit. Our Maximum Aggressive reference is 19x8.5J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mini Cooper S John Cooper Works Tuning Kit OE Wheel Specs
The 2008 Mini Cooper S John Cooper Works Tuning Kit (Performance Hatch) uses a 4x100 bolt pattern with a 56.1mm center bore. Factory wheels are 17x7J at ET42.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Mini Cooper S John Cooper Works Tuning Kit (2008) we drill the 4x100 pattern and cut the centre bore to 56.1mm 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.

Flush Fitment
For a flush look with minimal rubbing, 18x8J ET38 is the recommended starting point on a stock or mildly lowered Mini Cooper S John Cooper Works Tuning Kit.
Maximum Aggressive Fitment
19x8.5J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
1
What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Mini Cooper S John Cooper Works Tuning Kit owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x7J ET42 → ~5.65″ backspacing
- Flush: 18x8J ET38 → ~6.0″ backspacing
- Max: 19x8.5J ET35 → ~6.13″ 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 Mini spec, or want a wheel built to a custom offset for your Mini Cooper S John Cooper Works Tuning Kit? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Mini Cooper S John Cooper Works Tuning Kit (2008)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 4x100 pattern and the 56.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose — most Mini orders on this platform land somewhere between the 18x8J ET38 flush setup and the 19x8.5J ET35 aggressive setup referenced above.

What bolt pattern (PCD) does the Mini Cooper S John Cooper Works Tuning Kit use?
The 2008 Mini Cooper S John Cooper Works Tuning Kit uses a 4x100 bolt pattern.
How many lug bolts does the Mini Cooper S John Cooper Works Tuning Kit use?
The Mini Cooper S John Cooper Works Tuning Kit 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 Mini Cooper S John Cooper Works Tuning Kit?
The Mini Cooper S John Cooper Works Tuning Kit's center bore is 56.1mm. 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 Mini Cooper S John Cooper Works Tuning Kit?
Factory wheels on the Mini Cooper S John Cooper Works Tuning Kit are 17x7J at ET42.
What is the biggest wheel size I can fit on my Mini Cooper S John Cooper Works Tuning Kit without rubbing?
The most aggressive fitment we recommend without fender work is 19x8.5J at ET35 offset. 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 Mini Cooper S John Cooper Works Tuning Kit?
For a flush look with minimal to no rubbing, we recommend 18x8J at ET38 offset as a starting point on a stock or mildly lowered Mini Cooper S John Cooper Works Tuning Kit.
Do I need wheel spacers for my Mini Cooper S John Cooper Works Tuning Kit?
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 Mini Cooper S John Cooper Works Tuning Kit?
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" 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 Mini Cooper S John Cooper Works Tuning Kit?
The Mini Cooper S John Cooper Works Tuning Kit 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.
Vehicles With the Same Hub as the Mini Cooper S John Cooper Works Tuning Kit (4x100, 56.1 mm Bore)
In our database, 40 other vehicle entries from 9 makes use exactly the same 4x100 bolt pattern and 56.1 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.
4x100 is used by 6.9% of the vehicle pages in our English fitment guide (451 of 6,503); 9.1% of those also use a 56.1 mm center bore.
Hub-Centric Rings for a 56.1 mm Center Bore
A wheel with a center bore larger than 56.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 57.1 mm | 57.1 → 56.1 mm |
| 60.1 mm | 60.1 → 56.1 mm |
| 63.4 mm | 63.4 → 56.1 mm |
| 64.1 mm | 64.1 → 56.1 mm |
| 73.1 mm | 73.1 → 56.1 mm |
ANKUSI forged wheels are bored to exactly 56.1 mm for this vehicle, so no ring is needed.
