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
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Chevrolet Epica runs a 4x114.3 bolt pattern, 56.6mm center bore, and a 15x6.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x7.5J ET38, which tucks the tire under the fender lip on a stock-height Chevrolet Epica. Our Maximum Aggressive reference is 18x8.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Epica OE Wheel Specs
The 2006 Chevrolet Epica (Sedan) uses a 4x114.3 bolt pattern with a 56.6mm center bore. Factory wheels are 15x6.0J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
Flush Fitment
For a flush look, F/R 17x7.5J ET38 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Chevrolet Epica.
Maximum Aggressive Fitment
F/R 18x8.0J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases
The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: 15x6.0J ET44
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: 17x7.5J ET38
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: 18x8.0J ET35
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 15x6.0J ET44 → ~5.23″ backspacing
- Flush: 17x7.5J ET38 → ~5.75″ backspacing
- Max: 18x8.0J ET35 → ~5.88″ backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Chevrolet spec, or want a wheel built to a custom offset for your Chevrolet Epica? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 136 Nm (100 ft-lb). Covers most Chevrolet passenger cars and crossovers on M12 studs.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
