Expert Buying Guide for 1999 Acura NSX
For your 1999 Acura NSX, the bolt pattern is 5x114.3 with a center bore of 70.1mm. When selecting aftermarket wheels, hub-centric rings are mandatory to ensure proper centering and prevent vibrations. The offset is sensitive; the factory spec is around 40mm, but offsets from 35mm to 45mm can work with careful fitment checks. Always use the correct lug nuts: 12x1.5 thread pitch with a conical (60-degree) seat. Never use ball-seat lug nuts, as they can loosen and cause wheel detachment. Re-torque after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 80 ft-lbs after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using spacers without extended studs; the NSX has limited thread engagement.
- ✅ Check for brake caliper clearance, especially with aftermarket wheels, as the NSX has large brakes.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ Confirm bolt pattern carefully. 5x114.3 is often confused with other common 5-lug patterns.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
- ⚠️ This model has multiple bolt-pattern records across years. Match wheels to exact year/trim before purchase.

1999 Acura NSX — Frequently Asked Questions
What is the bolt pattern for a 1999 Acura NSX?
The 1999 Acura NSX uses a 5x114.3 bolt pattern (also called lug pattern or PCD). The center bore is 70.1mm and the offset is 40mm.
What other years of Acura NSX have the same bolt pattern as the 1999?
The Acura NSX uses the 5x114.3 pattern from 1992 through 2005. Wheels from any of these model years are dimensionally compatible with the 1999, provided the offset and center bore also match.
What is the center bore of a 1999 Acura NSX?
The factory center bore (hub bore) for the 1999 Acura NSX is 70.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
What is the factory wheel offset for a 1999 Acura NSX?
The OEM offset for the 1999 NSX is typically around 40mm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
Why is matching the 70.1mm center bore important for the 1999 NSX?
The 70.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
What does 40mm offset mean for the 1999 NSX?
An offset of 40mm means the wheel's mounting surface is 40mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Acura.
