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 Holden VY Commodore SS ships from the factory on a 5x120 bolt pattern with a 69.6mm center bore and a 18x8J ET48 wheel. Our flush reference for the Holden VY Commodore SS is 18x8.5J ET38.; our maximum aggressive reference is 19x9J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
Holden VY Commodore SS OE Wheel Specs
The Holden VY Commodore SS ships from the factory on 5x120 bolt pattern wheels with a 69.6mm center bore. The stock wheel size is 18x8J ET48, 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.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Holden VY Commodore SS (2003) we drill the 5x120 pattern on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.
