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 Lotus Elise Sport 240 Final Edition ships from the factory on a 4x100 bolt pattern with a 56.6mm center bore and a F 16x6J ET31 / R 17x8J ET38 wheel. Our flush reference for the Lotus Elise Sport 240 Final Edition is F 16x7J ET25 / R 17x8.5J ET30.; our maximum aggressive reference is F 17x7.5J ET22 / R 18x9J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
Lotus Elise Sport 240 Final Edition OE Wheel Specs
The Lotus Elise Sport 240 Final Edition ships from the factory on 4x100 bolt pattern wheels with a 56.6mm center bore. The stock wheel size is F 16x6J ET31 / R 17x8J ET38, 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 Lotus Elise Sport 240 Final Edition owners run F 16x7J ET25 / R 17x8.5J 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 17x7.5J ET22 / R 18x9J ET25. Chassis: Extremely sensitive to unsprung weight. Wheels: 4x100 PCD forged wheels. Tires: 195/50 R16 F, 225/45 R17 R. Clearance should be verified before ordering, especially on lowered cars.
