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.
Honda Prelude Si OE Wheel Specs
The 1992-1994 Honda Prelude Si (Sport Coupe) uses a 4x114.3 bolt pattern with a 64.1mm center bore. Factory wheels are 15x6.5J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
Flush Fitment
For a flush look, F/R 15x7.0J ET38 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Honda Prelude Si.
Maximum Aggressive Fitment
F/R 15x7.5J ET0 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 15x6.5J ET45 → ~5.52″ backspacing
- Flush: 15x7.0J ET38 → ~5.5″ backspacing
- Max: 15x7.5J ET0 → ~4.25″ 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 Honda spec, or want a wheel built to a custom offset for your Honda Prelude Si? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
