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
On a supercar, wheel weight is one of the few remaining places to cut rotational mass without touching the powertrain or chassis the factory already optimized. Forging gets there at the same structural margin as the OE wheel, which is exactly the trade a car built around outright performance rewards.
The Lamborghini Temerario Ad Personam ships from the factory on a 5x112 bolt pattern with a 66.5mm center bore and a F 20x9J ET40 / R 21x11.5J ET50 wheel. Our flush reference for the Lamborghini Temerario Ad Personam is F 20x9.5J ET35 / R 21x12J ET45.; our maximum aggressive reference is F 21x9.5J ET30 / R 22x12.5J ET40. — beyond that, expect clearance issues against the fender liner without further modification.
Lamborghini Temerario Ad Personam OE Wheel Specs
The Lamborghini Temerario Ad Personam ships from the factory on 5x112 bolt pattern wheels with a 66.5mm center bore. The stock wheel size is F 20x9J ET40 / R 21x11.5J ET50, 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.
Flush Fitment
For a flush look without any body modification, most Lamborghini Temerario Ad Personam owners run F 20x9.5J ET35 / R 21x12J ET45. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.
