The Acura NSX is a masterpiece of engineering that blends cutting-edge technology with exhilarating performance. One of the most effective ways to enhance the NSX’s already impressive capabilities is by upgrading to lightweight wheels. Lightweight wheels not only improve the overall aesthetics of your vehicle but also have a tangible impact on performance, handling, and efficiency.

In this comprehensive guide, Everyday Acura will walk you through everything you need to know about choosing the perfect lightweight wheels for your Acura NSX. From understanding the benefits and materials to selecting the right size and style, this guide will equip you with the knowledge to make an informed decision.

Why Choose Lightweight Wheels for Your Acura NSX?

Lightweight wheels offer numerous advantages over standard wheels, especially for high-performance vehicles like the Acura NSX. Here are some key reasons why upgrading to lightweight wheels is a smart move:

1. Improved Acceleration and Braking

Reducing the unsprung weight — the mass of components not supported by the suspension, including wheels and tires — directly affects how quickly your car can accelerate and brake. Lightweight wheels decrease rotational mass, meaning less energy is required to spin them up or slow them down. This translates to quicker acceleration and shorter stopping distances, essential for a sports car like the NSX.

2. Enhanced Handling and Cornering

Lower unsprung weight improves suspension response, enabling your NSX to better maintain tire contact with the road surface. This results in more precise handling, sharper cornering, and a more connected driving experience. Lightweight wheels reduce inertia, allowing for quicker directional changes and increased agility on both street and track.

3. Better Fuel Efficiency

Although the NSX is a performance-focused vehicle, improved fuel efficiency is an added benefit of lightweight wheels. Less weight means the engine doesn’t have to work as hard to move the car, which can lead to noticeable fuel savings over time, especially during city driving and stop-and-go traffic.

4. Reduced Strain on Suspension Components

By decreasing unsprung weight, lightweight wheels help reduce wear and tear on suspension components like shocks, springs, and bushings. This can extend the lifespan of these parts and improve overall vehicle reliability.

Materials Used in Lightweight Wheels

When choosing lightweight wheels for your Acura NSX, it’s important to understand the materials used in their construction. Each material offers a unique balance of weight, strength, cost, and durability.

1. Aluminum Alloy Wheels

Aluminum alloy wheels are the most common choice for lightweight wheels due to their excellent strength-to-weight ratio and affordability. They are made by casting or forging aluminum alloys, which provide a lightweight yet durable option. Forged aluminum wheels, in particular, offer superior strength and weight savings compared to cast wheels, making them a popular choice for performance vehicles like the NSX.

2. Magnesium Alloy Wheels

Magnesium wheels are even lighter than aluminum, offering significant reductions in unsprung weight. However, magnesium is more expensive and less corrosion-resistant, requiring special coatings and care. Magnesium wheels are typically found on high-end racing or track-focused vehicles where performance gains outweigh the higher maintenance requirements.

3. Carbon Fiber Wheels

Carbon fiber wheels represent the pinnacle of lightweight wheel technology. They offer unmatched strength and weight savings but come at a premium price. Carbon fiber wheels are extremely rigid and reduce rotational mass dramatically, enhancing performance. However, they may not be as durable under everyday driving conditions and require careful handling to avoid damage.

4. Steel Wheels

While steel wheels are generally heavier and not considered lightweight, some lightweight steel wheel designs exist. These are rare and typically not recommended for performance applications like the NSX.

How to Choose the Right Size and Fitment

Selecting the correct wheel size and fitment is crucial for maintaining your NSX’s performance and safety. Here are the key factors to consider:

1. Diameter

The NSX typically comes with wheels ranging from 19 to 20 inches in diameter. Increasing wheel diameter can improve aesthetics and allow for larger brake systems but may increase weight if not carefully selected. Lightweight wheels often allow for larger diameters without a significant weight penalty.

2. Width

Wider wheels provide a larger contact patch for the tires, improving grip and cornering ability. However, wider wheels can add weight and may require wider tires, affecting ride quality and fuel economy. It is essential to choose a width compatible with your tire selection and suspension setup.

3. Offset and Backspacing

Wheel offset determines how far the wheel sits inward or outward relative to the suspension. Correct offset ensures proper clearance from brake calipers, suspension components, and fenders. Improper offset can cause handling issues and premature wear on components. Always verify your chosen wheel’s offset matches Acura NSX specifications or is approved by a professional installer.

4. Bolt Pattern

The Acura NSX uses a specific bolt pattern (typically 5x120mm), which must be matched by your aftermarket wheels to ensure secure mounting. Using adapters or incorrect bolt patterns is generally discouraged as it can compromise safety and performance.

Several manufacturers specialize in high-quality lightweight wheels suitable for the Acura NSX. Here are some notable options:

  • BBS: Renowned for their forged wheels, BBS offers a range of lightweight designs that combine strength, durability, and style.
  • OZ Racing: Known for motorsport-inspired wheels, OZ Racing provides lightweight options that balance performance and aesthetics.
  • Enkei: Offers affordable, lightweight wheels using advanced manufacturing techniques such as MAT technology for enhanced strength.
  • HRE Performance Wheels: A premium brand specializing in forged and flow-formed wheels that emphasize lightweight construction and bespoke designs.

Considerations When Purchasing Lightweight Wheels

Beyond weight and aesthetics, several practical factors should influence your decision when selecting lightweight wheels for the NSX:

1. Durability and Use Case

Consider how you intend to use your NSX. If you primarily drive on the street, you may prioritize durability and resistance to curb damage. For track use, weight savings and performance take precedence, and wheels may require more frequent inspection and maintenance.

2. Cost

Lightweight wheels vary widely in price based on material, manufacturing process, and brand reputation. Establish a budget and balance performance gains with affordability. Forged aluminum wheels offer a good middle ground, while carbon fiber wheels are at the high end of the price spectrum.

3. Warranty and Support

Check the manufacturer’s warranty and after-sales support. Reputable brands often provide warranties covering structural integrity and finish, giving you peace of mind with your investment.

4. Tire Compatibility

Ensure the tires you plan to use are compatible with the new wheel size. Tires play a critical role in vehicle dynamics, and pairing the right tire with your lightweight wheels maximizes performance benefits.

Step-by-Step Guide to Installing Lightweight Wheels on Your NSX

Proper installation is key to enjoying the full benefits of lightweight wheels. Here’s a step-by-step overview:
