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
Hot hatches and performance compacts are built around quick direction changes, so rotational mass at the wheel has an outsized effect on how the car actually feels to drive. Forging trims that mass while holding the same strength margin as the factory wheel, which is exactly the trade-off this kind of platform rewards.
The Lancia Delta 1.8 Di Turbo Jet ships from the factory on a 4x98 bolt pattern with a 58.1mm center bore and a 18x7.5J ET31 wheel. Our flush reference for the Lancia Delta 1.8 Di Turbo Jet is 18x8J ET25.; our maximum aggressive reference is 19x8.5J ET22. — beyond that, expect clearance issues against the fender liner without further modification.
