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 Morgan Aero 8 ships from the factory on a 5x114.3 bolt pattern with a 67.1mm center bore and a F 18x8.5J ET35 / R 18x10J ET35 wheel. Our flush reference for the Morgan Aero 8 is F 19x9J ET25 / R 19x11J ET30.; our maximum aggressive reference is F 20x9.5J ET20 / R 20x11.5J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
Morgan Aero 8 OE Wheel Specs
The Morgan Aero 8 ships from the factory on 5x114.3 bolt pattern wheels with a 67.1mm center bore. The stock wheel size is F 18x8.5J ET35 / R 18x10J ET35, 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 Morgan Aero 8 owners run F 19x9J ET25 / R 19x11J ET30. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.
Maximum Aggressive Fitment
Owners chasing a more aggressive stance push to F 20x9.5J ET20 / R 20x11.5J ET25. Adjustable sport suspension; 18-inch forged wheels; AP Racing brakes; Michelin Pilot Sport 4S (F: 225/40 R18, R: 255/35 R18). Note: Fifth and final generation of the BMW V8 powered aluminum chassis Aero sports car. Clearance should be verified before ordering, especially on lowered cars.
