2004 Brabus Ultimate 101 Wheels & Rims: Bolt Pattern, Offset & Sizes
Fitting Brabus Ultimate 101 wheels? This page gives the 2004 Brabus Ultimate 101 bolt pattern (3x112), centre bore, factory rim size and the offset range for aftermarket and forged Brabus Ultimate 101 rims: the same spec sheet ANKUSI uses when machining forged wheels for this car.
Quick answer: The 2004 Brabus Ultimate 101 uses a 3x112 bolt pattern with a 57.1 mm centre bore and M14x1.5 lug bolts. Factory wheels: F: 17x7.0J R: 17x8.5J. For aftermarket wheels, 18x7.5J ET15 front / 18x9.0J ET15 rear sits flush and 18x8.0J ET10 front / 18x9.5J ET10 rear is the most aggressive fit.
Forged wheels for the 2004 Brabus Ultimate 101 — drilled 3x112 with a 57.1 mm centre bore, built to the offset you choose. From $220 per wheel, made to order in 20–25 days.

Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | F: 17x7.0J R: 17x8.5J |
| Flush Fitment | F 18x7.5J ET15 / R 18x9.0J ET15 |
| Maximum Aggressive | F 18x8.0J ET10 / R 18x9.5J ET10 |
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
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Brabus Ultimate 101 runs a 3x112 bolt pattern, 57.1mm center bore, and a F: 17x7.0J wheel from the factory. Our Flush Fitment reference is F 18x7.5J ET15 / R 18x9.0J ET15, which tucks the tire under the fender lip on a stock-height Brabus Ultimate 101. Our Maximum Aggressive reference is F 18x8.0J ET10 / R 18x9.5J ET10 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Brabus Ultimate 101 OE Wheel Specs
The 2004 Brabus Ultimate 101 (Roadster) uses a 3x112 bolt pattern with a 57.1mm center bore. Factory wheels are F: 17x7.0J R: 17x8.5J.
Why the factory spec works for most owners:
- Preserves the factory-tuned ride and steering feel
- A mainstream size for this segment, keeping tire choice wide and prices reasonable
- Leaves full clearance for the stock brakes and suspension hardware
- Keeps handling predictable and consistent in everyday conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Brabus Ultimate 101 (2004) we drill the 3x112 pattern and cut the centre bore to 57.1mm 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.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 17x7.0J ET20 → ~4.79″ F backspacing, R 17x8.5J ET20 → ~5.54″ R backspacing
- Flush: F 18x7.5J ET15 → ~4.84″ F backspacing, R 18x9.0J ET15 → ~5.59″ R backspacing
- Max: F 18x8.0J ET10 → ~4.89″ F backspacing, R 18x9.5J ET10 → ~5.64″ R backspacing
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 Brabus spec, or want a wheel built to a custom offset for your Brabus Ultimate 101? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Brabus Ultimate 101 (3x112, 57.1 mm Bore)
In our database, 12 other vehicle entries from 2 makes use exactly the same 3x112 bolt pattern and 57.1 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.
3x112 is used by 0.2% of the vehicle pages in our English fitment guide (13 of 6,503); 100.0% of those also use a 57.1 mm center bore.
Hub-Centric Rings for a 57.1 mm Center Bore
A wheel with a center bore larger than 57.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 57.1 mm |
| 63.4 mm | 63.4 → 57.1 mm |
| 64.1 mm | 64.1 → 57.1 mm |
| 65.1 mm | 65.1 → 57.1 mm |
| 73.1 mm | 73.1 → 57.1 mm |
ANKUSI forged wheels are bored to exactly 57.1 mm for this vehicle, so no ring is needed.
