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
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 TVR Cerbera ships from the factory on a 5x114.3 bolt pattern with a 68.1mm center bore and a F 16x7.5J ET35 / R 16x8.5J ET35 wheel. Our flush reference for the TVR Cerbera is F 17x8J ET30 / R 17x9J ET30.; our maximum aggressive reference is F 18x8.5J ET25 / R 18x9.5J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
TVR Cerbera OE Wheel Specs
The TVR Cerbera ships from the factory on 5x114.3 bolt pattern wheels with a 68.1mm center bore. The stock wheel size is F 16x7.5J ET35 / R 16x8.5J 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 TVR Cerbera owners run F 17x8J ET30 / R 17x9J 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 18x8.5J ET25 / R 18x9.5J ET25. Gaz Gold coilovers; 17/18-inch multi-piece forged wheels; AP Racing 4-piston brakes; Michelin Pilot Sport 4 tires. Note: 2+2 layout available with either a Speed Six or AJP8 engine; very light body with immense performance requiring precise alignment setup. Clearance should be verified before ordering, especially on lowered cars.
