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
With less structural stiffness from the missing roof, a convertible's suspension tuning leans more heavily on unsprung mass control. Forged construction keeps wheel weight down at the same strength rating, which is one less variable working against the Ferrari Amalfi Spider's chassis.
The Ferrari Amalfi Spider runs a 5x114.3 bolt pattern, 67.1mm center bore, and a F: 20x8.0J wheel from the factory. Our Flush Fitment reference is F 20x8.5J ET38 / R 20x10.5J ET45, which tucks the tire under the fender lip on a stock-height Ferrari Amalfi Spider. Our Maximum Aggressive reference is F 21x9.0J ET35 / R 21x11.0J ET40 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ferrari Amalfi Spider OE Wheel Specs
The 2027 Ferrari Amalfi Spider (Convertible) uses a 5x114.3 bolt pattern with a 67.1mm center bore. Factory wheels are F: 20x8.0J R: 20x10.0J.
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 Ferrari Amalfi Spider (2027) we drill the 5x114.3 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.

Flush Fitment
For a flush look with minimal rubbing, F 20x8.5J ET38 / R 20x10.5J ET45 is the recommended starting point on a stock or mildly lowered Ferrari Amalfi Spider.
Maximum Aggressive Fitment
F 21x9.0J ET35 / R 21x11.0J ET40 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 20x8.0J ET44 → ~6.23″ F backspacing, R 20x10.0J ET52 → ~7.55″ R backspacing
- Flush: F 20x8.5J ET38 → ~6.25″ F backspacing, R 20x10.5J ET45 → ~7.52″ R backspacing
- Max: F 21x9.0J ET35 → ~6.38″ F backspacing, R 21x11.0J ET40 → ~7.57″ 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 Ferrari spec, or want a wheel built to a custom offset for your Ferrari Amalfi Spider? 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 Ferrari Amalfi Spider (2027)
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 5x114.3 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 5x114.3 pattern — each one is re-cut to your sizes and offsets:
