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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Hennessey Exorcist Camaro ZL1 Final Ed ships from the factory on a 5x120 bolt pattern with a 66.9mm center bore and a F 20x10J ET20 / R 20x11J ET43 wheel. Our flush reference for the Hennessey Exorcist Camaro ZL1 Final Ed is F 20x10.5J ET15 / R 20x11.5J ET38.; our maximum aggressive reference is F 20x11J ET10 / R 20x12J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
Hennessey Exorcist Camaro ZL1 Final Ed OE Wheel Specs
The Hennessey Exorcist Camaro ZL1 Final Ed ships from the factory on 5x120 bolt pattern wheels with a 66.9mm center bore. The stock wheel size is F 20x10J ET20 / R 20x11J ET43, 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 Hennessey Exorcist Camaro ZL1 Final Ed owners run F 20x10.5J ET15 / R 20x11.5J ET38. 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 20x11J ET10 / R 20x12J ET35. Chassis: MagneRide suspension. Wheels: Standard ZL1 fitment or Hennessey forged. Brakes: 6-piston Brembo clearance. Clearance should be verified before ordering, especially on lowered cars.
