Fitting Ferrari 575M Superamerica wheels? This page gives the 2005 Ferrari 575M Superamerica bolt pattern (5x108), centre bore, factory rim size and the offset range for aftermarket and forged Ferrari 575M Superamerica rims: the same spec sheet ANKUSI uses when machining forged wheels for this car.
Ferrari 575M Superamerica (2005): 5x108 bolt pattern, 67.1mm center bore. Factory wheels: F: 19x8.5J R: 19x10.5J. Reference fitment ranges.

| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | F: 19x8.5J R: 19x10.5J |
| Flush Fitment | F 19x9.0J ET38 / R 19x11.5J ET30 |
| Maximum Aggressive | F 20x9.5J ET35 / R 20x12.0J ET25 |
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.
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 Ferrari 575M Superamerica runs a 5x108 bolt pattern, 67.1mm center bore, and a F: 19x8.5J wheel from the factory. Our Flush Fitment reference is F 19x9.0J ET38 / R 19x11.5J ET30, which tucks the tire under the fender lip on a stock-height Ferrari 575M Superamerica. Our Maximum Aggressive reference is F 20x9.5J ET35 / R 20x12.0J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
The 2005 Ferrari 575M Superamerica (Convertible) uses a 5x108 bolt pattern with a 67.1mm center bore. Factory wheels are F: 19x8.5J R: 19x10.5J.
Why the factory spec works for most owners:
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ferrari 575M Superamerica (2005) 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.

For a flush look with minimal rubbing, F 19x9.0J ET38 / R 19x11.5J ET30 is the recommended starting point on a stock or mildly lowered Ferrari 575M Superamerica.
F 20x9.5J ET35 / R 20x12.0J ET25 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: F 19x8.5J ET43 / R 19x10.5J ET38
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: F 19x9.0J ET38 / R 19x11.5J ET30
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: F 20x9.5J ET35 / R 20x12.0J ET25

Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
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 Ferrari spec, or want a wheel built to a custom offset for your Ferrari 575M Superamerica? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
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 5x108 pattern and the 67.1mm 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.
Designs we already tool for the 5x108 pattern — each one is re-cut to your sizes and offsets:
Ferrari 488 / Audi R8 Forged Wheels – Gloss Black Directional Multi-Spoke (5-Lug)
Ferrari 488 / Audi R8 Forged Wheels – Satin Black Petal-Spoke (5-Lug)
Audi RS5 Sedan Forged Wheels – Gloss Black 5-Spoke Y-Design (20-21in, 5x112)
APEX ARC-8-Style Bright Silver 8 Y-Spoke Mesh Forged Wheels – BMW M3 E46 / BMW 3 Series F30 Fitment (5-Lug)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 7.5% of the vehicle entries in our database (479 of 6,396); 7.1% of those also use 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.
