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 Lancia Delta Integrale ships from the factory on a 5x98 bolt pattern with a 58.1mm center bore and a 15x7.5J ET37 wheel. Our flush reference for the Lancia Delta Integrale is 17x8J ET25.; our maximum aggressive reference is 17x8.5J ET20. — beyond that, expect clearance issues against the fender liner without further modification.
Lancia Delta Integrale OE Wheel Specs
The Lancia Delta Integrale ships from the factory on 5x98 bolt pattern wheels with a 58.1mm center bore. The stock wheel size is 15x7.5J ET37, 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 Lancia Delta Integrale owners run 17x8J ET25. 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 17x8.5J ET20. Chassis: Track/Rally coilovers. Wheels: Evo models use 5x98 (earlier 8V/16V used 4x98). Brakes: Clear Brembo calipers. Tires: 215/40 R17. Clearance should be verified before ordering, especially on lowered cars.
