Expert Buying Guide for 1998 Acura NSX
For your 1998 Acura NSX, the critical center bore is 70.1mm. Aftermarket wheels often have a larger bore (73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The ideal offset is around 40mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.5) and seat type—factory wheels use a ball seat, while many aftermarket wheels require a conical (60-degree) seat. Using the wrong seat can lead to wheel loosening. Cross-compatible wheels from 1992–2005 NSX models fit directly. Prioritize safety: verify all specs before installation.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 80 ft-lbs after 50 miles of driving to ensure proper seating.
- ✅ If using aftermarket wheels, always install hub-centric rings (70.1mm ID to wheel's bore OD) to prevent vibrations.
- ✅ Check brake caliper clearance: some 18-inch wheels may require spacers or caliper grinding on the NSX.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
