Recorded vehicle-side thread for the 1998 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.

1998 Acura NSX Wheel Fitment Guide

I write this like I do in the bay. Straight to the point, safe, and verified on the car before sign-off.

Spec Value Notes
Bolt pattern 5x114.3 Match studs and PCD exactly.
Center bore 64.1 mm Wheels can be larger with rings. Not smaller.
Thread size M12 x 1.5 Use matching nuts or bolts for the wheel seat type.
Rim size 16 x 7.0 in Provided OEM reference. May reflect one axle only.
Offset ET 55 mm Stay close unless the calculator proves clearance.
Backspacing 5.67 in Use to confirm inner clearance.
Tire size 215/45R16 Provided OEM reference. Verify what is on your car.

Note: The NSX often uses staggered setups by model and market. This page only lists values provided. If your trim differs, confirm both axles using the on-page calculator and OEM sources before buying.

tl;dr

  • Use the calculator to compare donors against your NSX.
  • Match 5x114.3 and M12x1.5. Keep center bore 64.1 mm or larger with rings.
  • Start from 16x7 ET55, 215/45R16 as your baseline.
  • Make small offset and width changes, then check inner and outer clearance.
  • Do a test fit. Torque to OEM spec. Re-torque after 50–100 miles.

Recommendation

Work in a simple lifecycle: baseline, compare, simulate, test, then install.

1) Baseline your car

  • Confirm what is actually on the car now. Read tire sidewalls and wheel stamps.
  • If front and rear differ, record both. The provided values may be for one axle.
  • Check for spacers or aftermarket studs. Note any changes.

2) Use the calculator

  • Set Installed on to 1998 Acura NSX.
  • Enter Custom wheel size as 16x7 ET55. Enter tire 215/45R16.
  • For a donor, input that vehicle or a custom size you are considering.
  • Review inner clearance to the strut and outer poke to the fender.
  • Adjust width and offset in small steps. Watch both inner and outer changes.
  • If you change rim diameter, the tool updates tire diameter. Verify arch clearance lock-to-lock.

3) Fitment rules I follow on NSX

  • Keep bolt pattern exact at 5x114.3.
  • Offset close to ET55 unless the calculator shows safe clearance.
  • Center bore 64.1 mm hubcentric. Larger bores need proper rings.
  • Maintain tire overall diameter near OEM to protect handling and ABS behavior.
  • Check brake caliper spoke clearance. Profile varies by wheel design.

4) Hardware and seating

  • Use M12x1.5 hardware with correct seat type for the wheel.
  • If using aftermarket wheels with larger bores, use quality 64.1 mm rings.
  • Torque to the OEM spec from the service manual. Do not guess.

Impact

  • Offset changes affect scrub radius and steering feel.
  • Wider wheels can add grip but reduce inner clearance.
  • Larger diameter may alter effective gearing and speedometer reading.
  • Tire sidewall changes affect ride, turn-in, and braking feedback.
  • Unsprung weight changes will be felt in damping and response.

Risks

  • Inner rub on strut or liner from excessive backspacing.
  • Outer poke contacting fender on compression or full lock.
  • Brake caliper interference with tight-spoke designs.
  • Vibration from non-hubcentric mounting without rings.
  • Insufficient thread engagement if studs are short or washers used.
  • Load rating too low for vehicle weight and use.
  • TPMS compatibility if fitted. Some markets vary.

Next actions

Checklist

  • Measure current front and rear wheel and tire sizes on the car.
  • In the calculator, set Installed on to 1998 Acura NSX.
  • Enter the provided baseline: 16x7 ET55 with 215/45R16.
  • Compare your target wheels. Confirm inner and outer clearances.
  • Confirm bolt pattern 5x114.3 and thread M12x1.5 on the new wheels.
  • Check center bore. If larger than 64.1 mm, add 64.1 mm rings.
  • Verify brake caliper clearance using the wheel’s spoke template if available.
  • Confirm torque spec from the OEM service manual.
  • Test fit one corner. Spin by hand. Check lock-to-lock.
  • Install all four. Torque in a star pattern. Re-torque after 50–100 miles.

Helpful tools

If a specification on your car differs, verify with the door-jamb label and the Acura service manual. Then re-run the calculator for each axle. That keeps the result accurate to your build.

Gotchas

  • Some NSX trims and markets use staggered sizes. Confirm both axles.
  • Do not rely on tire size alone. Offset drives clearance outcomes.
  • Aftermarket wheel seat type can differ. Match conical vs ball seat.
  • Spacers change effective offset. Recalculate if spacers are used.

Keep changes controlled, verify with the calculator, and test fit. That process avoids surprises and protects the chassis feel Acura intended.

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.
