1994-2005 Acura NSX Wheels: A Guide to Sizes, Offsets & Forged Originals

Major Generation & Model Year Wheel Variations

The 1994-2005 Acura NSX saw several key changes to its factory wheels, primarily driven by updates to the braking system and styling. All OEM wheels are forged aluminum, prized for their strength and low weight. Identifying the correct wheel for your year is essential for proper fitment, brake clearance, and maintaining the car's intended performance characteristics.

1994-1996: Forged 7-Spoke Wheels

For the 1994 model year, the NSX moved from the original 15"/16" five-spoke design to a new, larger 7-spoke forged alloy wheel. This change accommodated larger brake calipers and set the stage for future designs. These wheels are often finished in Solaris Silver (paint code NH-536M).

• Front Size: 16x7.0"
• Rear Size: 17x8.5"
• Common Finishes: Silver, Chrome

1997-2001: Updated 7-Spoke Forged Wheels

With the introduction of a larger 3.2L engine and bigger front brake calipers in 1997, the wheels were updated again. While visually similar to the 1994-1996 wheels, they feature different offsets to clear the new brake hardware. These wheels were available in several finishes, including silver, chrome, and a special Grand Prix White for certain 1997 models.

• Front Size: 16x7.0"
• Rear Size: 17x8.5"

2002-2005: Facelift 7-Spoke Forged Wheels

The 2002 facelift brought the most significant change, with both front and rear wheels moving to a 17-inch diameter to clear even larger brakes and update the car's appearance. These wheels have a slightly different spoke design, often described as being more 'grooved'. Attempting to fit these wheels on an early (1991-1996) NSX will cause the spokes to hit the front brake calipers unless a 5mm spacer is used or the brakes are upgraded to the 1997+ specification.

• Front Size: 17x7.0"
• Rear Size: 17x9.0"

Special Edition: 1999 Zanardi Edition BBS Wheels

Exclusive to the 51 Alex Zanardi Edition models built in 1999, these are lightweight forged BBS wheels. They feature a unique 16-spoke design and a specific "Washi Gray" finish. These are highly sought after and command a premium price.

• Front Size: 16x7.0"
• Rear Size: 17x8.5"
• Finish: Washi Gray Metallic

Technical Specifications

Understanding the core specifications is crucial when buying replacement wheels, as incorrect specs can lead to dangerous fitment issues.

Understanding Offset

Offset is the distance from the wheel's mounting surface to its centerline. Using a wheel with the wrong offset can cause serious problems:

• Too High Offset: The wheel sits too far inward, potentially rubbing against suspension components or the inner fender liner.
• Too Low Offset: The wheel sticks out too far, which can cause it to rub on the outer fender, especially during turns or suspension compression. This also increases stress on the wheel bearings and can negatively affect the car's steering geometry and handling.

OEM offsets for the 1994-2005 NSX vary by year and axle. For example, 1997-2001 models used a +55mm offset for the front wheels and a +60mm offset for the rears. Always verify the offset for the specific wheel you are purchasing.

Symptoms of a Damaged Wheel

A damaged wheel is a serious safety concern. Be aware of these common symptoms:

• Vibration or Shaking: A bent wheel will often cause a noticeable vibration in the steering wheel or through the chassis 🎬 Watch this video to see common NSX wheel and steering issues, which typically gets worse with speed.
• Constant Air Loss: A slow, persistent leak that can't be traced to the tire valve or a puncture may be caused by a hairline crack in the wheel, often on the inner barrel or near the bead seat where the tire seals.
• Visible Damage: Obvious signs like bends in the wheel lip (especially the inner lip, which is harder to see), cracks radiating from the lug holes, or deep gouges are clear indicators the wheel needs replacement or professional repair.
• Difficulty Balancing: If a tire shop reports that a wheel requires an excessive amount of weight to balance, it is likely bent.

Known Issues, Recalls, and TSBs

While there have been no specific NHTSA recalls issued for the wheels on the 1994-2005 Acura NSX, owners should be aware of related issues. The primary concerns are damage from road hazards due to the car's low profile and the high cost of replacement. Some owners on forums have noted that the steering rack bushings can wear out over time, causing a clunking noise that can sometimes be mistaken for a suspension or wheel issue. There are no official Technical Service Bulletins (TSBs) related to wheel failure for this period, though some exist for later model year wheels.

Buyer's Guide: How to Inspect a Used NSX Wheel

Due to the high cost of new OEM wheels, buying a used one is a common choice. A thorough inspection is critical to ensure you are getting a safe, usable part.

Verifying Compatibility: The Most Important Step

Before you even look at the condition, confirm the wheel is correct for your NSX. Check the size (diameter and width) and part number stamped on the back. Be absolutely sure you are buying a front or a rear wheel as needed—they are not interchangeable. Remember the key brake clearance differences between 1994-1996, 1997-2001, and 2002-2005 models.

Physical Inspection Checklist

• Check for Bends: Lay the wheel on a flat surface and look for any wobbling. Roll it on the ground and watch the inner and outer lips. Any deviation or wobble indicates a bend. Even a minor bend can cause vibrations that are impossible to balance out.
• Find Hairline Cracks: Clean the wheel thoroughly and inspect it under bright light. Pay close attention to the inner barrel, the area where the spokes meet the rim, and around the lug nut holes. Cracks are a major safety hazard and often make the wheel non-repairable.
• Spot Previous Repairs: Look for signs of welding on the back side of the wheel. While professional welds can be safe, they can also indicate a severe previous impact. Also, look for areas where the paint finish is uneven or has a different texture, which could hide body filler used to mask cosmetic damage.
• Inspect Lug Nut Seats: The tapered holes where the lug nuts sit should be clean and free of gouges or distortion. Damaged seats can prevent the lug nuts from torquing down correctly.
• Check for Corrosion: Look for bubbling or flaking under the paint or clear coat. This is common on wheels that have seen road salt. While often cosmetic, severe corrosion can compromise the wheel's structural integrity over time.

OEM vs. Aftermarket NSX Wheels

Original Acura NSX wheels are die-forged, making them exceptionally strong and light. Many cheaper aftermarket wheels are cast, which is a less expensive process that results in a heavier and more brittle wheel. While high-quality forged aftermarket wheels exist, a used OEM wheel is often a better value, providing proven strength, durability, and perfect fitment without requiring hub-centric rings or special lug nuts.

Verifying Paint & Finish

Where to Find Your Acura's Paint Code

The body paint code for your NSX is located on a sticker in the driver's side door jamb. This code is essential for ordering touch-up paint for the car's body. However, wheel colors often have their own separate codes or names.

Common NSX Wheel Finishes

Standard wheels were typically silver. For example, 1994-1996 wheels were often Solaris Silver (NH-536M). Other options included chrome and special colors like Grand Prix White on certain models and Washi Gray for the Zanardi edition. When buying a used wheel, a perfect color match can be difficult due to age and sun exposure. Refinishing may be necessary to match your existing set perfectly.

Cost of an Acura NSX Wheel (1994-2005)

The cost can vary significantly based on model year, condition, and whether it is a standard or special edition wheel.
