Recorded vehicle-side thread for the 1993 Acura NSX is M12x1.5. This donor year is recorded as M14x1.5. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

Donor width/offset sits outside the known OEM envelope for this vehicle. Recorded vehicle-side thread differs (M14x1.5 on the donor year vs M12x1.5 on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset.

1993 Acura NSX Wheel Fitment Guide

You want clear, safe guidance. I steward risks first, aesthetics second. Let’s ground this in what we actually know about this 1993 NSX, then work the edge cases and mitigations with the on-page calculator.

1. Baseline

These values are the known OEM fitment details captured for this page. Items marked unknown may vary by trim or axle. Do not guess them. Confirm with the calculator, the owner’s manual, or an Acura dealer parts catalog.

Spec Value Notes
Bolt pattern Unknown Count studs and measure PCD. Confirm with OEM sources.
Center bore Unknown Measure hub lip with a caliper. Use hub rings if needed.
Thread size Unknown Verify on a single stud with a thread gauge.
Rim diameter 15 in May reflect one axle. Verify front and rear separately.
Rim width 6.5 in Check both axles. NSX often ran staggered setups.
Wheel offset ET 55 mm Primary datum for inner and outer clearance modeling.
Backspacing 5.42 in Aligns with 6.5 in width and ET 55 mm baseline.
Tire size 205/50R15 Use as baseline diameter. Compare alternatives in the calculator.

Use the wheelinterchange.com calculator to compare donor wheels to this NSX. Changing rim diameter updates the compared tire diameter automatically, which simplifies diameter-matching checks.

2. Edge cases

The NSX chassis is sensitive. Small changes can push geometry outside safe margins. Here are the common trouble spots I see:

  • Unknown axle split. One axle may be 15x6.5 ET55 while the other differs. Treat each axle separately.
  • Brake caliper clearance. Spokes that curve in may contact calipers under heat and flex.
  • Inner strut and knuckle clearance. Higher offset or wider wheels may rub the upright at full lock.
  • Fender and liner contact. Lower offset or wider tires may touch on compression or steering.
  • Hub-centric fit. An oversized center bore without rings can cause vibration.
  • Lug seat mismatch. Conical vs ball vs flat seats must match the wheel design.
  • Stud length with spacers. Spacers without adequate thread engagement reduce clamp load.
  • Tire diameter creep. A small increase stacks with suspension travel and can rub unexpectedly.
  • Unsprung mass. Heavier wheels can change damping behavior and braking feel.

3. Detection

Before you buy or mount anything, walk through these checks. The goal is to find conflicts early.

  • Baseline in the calculator. Set “Installed on” to 1993 Acura NSX. Input the known OEM wheel and tire values above for each axle as your baseline.
  • Donor comparison. Enter the donor vehicle wheel, or use Custom wheel size and Custom tire size.
  • Offset drift. Watch inner and outer poke. Try to keep inner clearance positive and outer poke modest.
  • Diameter control. Let the calculator update tire diameter with rim changes. Keep overall diameter change small to protect ABS and speedometer logic.
  • Caliper check. Ask for a wheel brake template from the wheel maker when possible. At minimum, verify spoke-to-caliper clearance visually during test fit.
  • Hub bore measure. Use a digital caliper on the hub lip to confirm center bore size.
  • Bolt pattern confirm. Count studs and measure PCD using a pattern reference or gauge. Do not assume.
  • Thread size confirm. Test one lug with a metric thread pitch gauge. Feel for smooth start by hand.
  • Spin and steer test. With the car on stands, torque two nuts and spin the wheel. Turn lock to lock. Check inside and outside for contact.

Helpful tools if you need them: digital caliper, metric thread pitch gauge, hub centric rings, torque wrench.

4. Mitigations

When the calculator or test fit flags risk, these steps usually resolve it.

  • Keep offset close. Aim to stay near ET 55 mm on this baseline. Small moves reduce geometry shock.
  • Use hub-centric rings. Size rings to the hub bore you measured and the wheel center bore.
  • Spacer strategy. Use hub-centric spacers only. Increase stud length or use extended studs when needed.
  • Mind lug seats. Match nut seat to the wheel seat style. Replace hardware if uncertain.
  • Control diameter. Select a tire that keeps overall diameter near the OEM reference.
  • Confirm load rating. Wheel and tire load ratings should meet or exceed OEM requirements.
  • Fresh torque. Hand start every nut. Torque in a star pattern. Re-torque after 50 to 100 miles.
  • Alignment check. After any wheel size change, verify alignment to prevent edge wear.

5. Safe defaults

When you want a conservative setup without deep trial and error, these defaults help. They are not promises. They are mitigations that have worked well in similar cases.

  • Start from 15x6.5 ET55 with 205/50R15 as the modeling baseline in the calculator.
  • Width change within about +0.5 to +1.0 inch per axle, evaluated separately.
  • Offset within about ±5 to ±7 mm of the OEM baseline to preserve clearances.
  • Overall tire diameter change within about 1 to 2 percent.
  • Maintain visible spoke-to-caliper clearance. A few millimeters margin under heat is prudent.
  • Hub-centric fit using rings if the wheel center bore is larger than the hub.

If a value on this page is unknown, treat it as a blocker until you confirm it. The calculator will help visualize geometry, but it will not replace a verified bolt pattern, center bore, or thread size.

6. Checklist

  • Identify whether your values above apply to front, rear, or both. Confirm per axle.
  • Measure hub center bore with a caliper. Record to 0.1 mm if possible.
  • Confirm bolt pattern by stud count and PCD measurement.
  • Confirm lug thread

Methodology and sources

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
