Expert Buying Guide for 1994 Chevrolet Sportvan G20
For your 1994 Chevrolet Sportvan G20, the bolt pattern is 5x127mm with a critical center bore of 78.3mm. Aftermarket wheels often have a larger bore, so hub-centric rings are mandatory to prevent vibration and ensure proper load distribution. The offset range is 0-15mm; staying within this range avoids rubbing on suspension or body components. Always use lug nuts with the correct thread pitch (1/2-20) and seat type—factory wheels use a conical (60-degree) seat, while aftermarket wheels may require ball-seat or shank-style nuts. Incorrect lug nuts can cause wheel loosening. Re-torque after 50-100 miles of driving.

- ✅ Verify offset: 0-15mm is safe; lower offset pushes wheels outward, risking fender contact.
- ✅ Re-torque lug nuts to 140 ft-lbs after 50-100 miles; use a torque wrench, not an impact gun.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).
