Upgrading the wheels on your 2020 Acura NSX is one of the most effective and transformative ways to enhance handling, improve overall driving dynamics, and elevate the vehicle’s aesthetic appeal. Lightweight wheels reduce unsprung mass—the weight not supported by the suspension—which significantly benefits acceleration, cornering precision, and braking response. By choosing the right set of lightweight wheels, you can unlock the full potential of your NSX’s advanced hybrid powertrain and sophisticated chassis, making every drive more exhilarating and controlled.

Understanding the Impact of Lightweight Wheels on the NSX’s Performance

The 2020 Acura NSX is a technological marvel, blending a twin-turbo V6 engine with three electric motors to deliver exceptional power and torque distribution. However, the benefits of this powertrain can only be fully realized when the vehicle’s rotating components are as light and responsive as possible. Lightweight wheels play a crucial role in this regard.

Reducing Rotational Mass

Wheels are part of the vehicle’s rotational mass—the weight that must be spun by the engine to move the car. Heavier wheels require more energy to accelerate and decelerate, which can dull throttle response and increase braking distances. Lightweight wheels reduce this rotational inertia, allowing the NSX to accelerate more quickly from a standstill and respond faster to driver inputs. This translates into sharper, more immediate handling, especially noticeable during spirited driving or on a track.

Lowering Unsprung Weight

Unsprung weight refers to components like wheels, tires, and brakes that are not supported by the suspension springs. Reducing unsprung weight improves the suspension’s ability to keep the tires in contact with the road surface, enhancing grip and ride quality. For the NSX, which features a sophisticated double-wishbone front suspension and multi-link rear suspension, lowering unsprung mass allows the dampers and springs to work more effectively, smoothing out bumps and maintaining composure through corners.

Improving Fuel Efficiency and Brake Performance

While the NSX is a hybrid and already efficient, lightweight wheels contribute to better fuel economy by decreasing the load on the engine and electric motors. Additionally, less weight means the brakes have less momentum to overcome when slowing the car, resulting in reduced brake fade and improved stopping power during aggressive driving sessions.

Key Considerations When Choosing Lightweight Wheels for the 2020 Acura NSX

Selecting the ideal set of lightweight wheels for your NSX requires careful attention to specifications and quality. Here are the primary factors to consider:

Size and Fitment

The factory wheels on the 2020 NSX typically measure 19 inches in the front and 20 inches in the rear. When upgrading, maintaining the correct diameter and width is essential to preserve the vehicle’s handling balance. Wheels that are too large or too narrow can negatively affect tire fitment, suspension geometry, and overall driving dynamics. It’s also important to match the wheel’s offset to ensure proper clearance with brake components and suspension arms.

Material and Manufacturing Process

The most common materials for lightweight wheels are forged aluminum and flow-formed aluminum. Forged wheels, like those from BBS and HRE, offer superior strength-to-weight ratios due to their dense, uniform structure. Flow-formed wheels, such as the Enkei RPF1, are more affordable and provide excellent weight savings through a specialized manufacturing process that stretches the wheel barrel. Both types are suitable for high-performance driving, but forged wheels tend to be more durable and resistant to fatigue.

Design and Aerodynamics

Wheel design can influence not only aesthetics but also aerodynamic efficiency and brake cooling. Wheels with open spoke designs facilitate better airflow to brake components, helping to dissipate heat during intense driving. Conversely, more closed designs may reduce drag but could increase brake temperatures. When choosing wheels for the NSX, consider designs that balance style, functionality, and cooling performance.

Durability and Quality Assurance

High-performance wheels must withstand the stresses of aggressive driving and occasional track use. Opt for reputable brands that adhere to stringent quality control standards and offer warranties. This ensures your investment protects both performance and safety.

Top Lightweight Wheel Options for the 2020 Acura NSX

Below are some of the best lightweight wheels available for the 2020 Acura NSX, each offering unique benefits tailored to different driving preferences and budgets.

  • BBS FI-R Series: Renowned for their forged construction, the BBS FI-R wheels provide an exceptional combination of low weight, high strength, and durability. Designed with motorsport pedigree in mind, these wheels typically weigh around 19 pounds for a 19-inch size—significantly lighter than many OEM wheels. Their multi-spoke design also aids in brake cooling, making them an excellent choice for both street and track use.
  • OZ Racing Ultraleggera: A favorite among track enthusiasts, the OZ Ultraleggera wheels are crafted using a flow-forming process that results in an ultra-lightweight yet strong wheel. With their classic mesh spoke design and competitive weight (approximately 15 pounds for a 17-inch size), these wheels excel in reducing unsprung mass and rotational inertia. While slightly more common in smaller diameters, OZ offers custom sizes to fit the NSX, providing a perfect blend of performance and style.
  • Enkei RPF1: The Enkei RPF1 is widely regarded for its outstanding price-to-performance ratio. Utilizing Enkei’s proprietary MAT (Most Advanced Technology) process, these wheels achieve remarkable weight savings without compromising strength. The RPF1’s split-spoke design also promotes effective brake cooling. Many NSX owners opt for these wheels for spirited street driving and occasional track days due to their affordability and proven reliability.
  • HRE FF01: HRE’s FF01 series offers fully forged wheels that combine lightweight engineering with bespoke aesthetics. These wheels can be custom-finished in a range of colors and styles to complement the NSX’s aggressive looks. Weighing approximately 18 to 20 pounds depending on size, the FF01 wheels provide an ideal balance of performance and luxury. Their monoblock forged construction ensures exceptional rigidity and longevity under demanding conditions.

Additional Performance Benefits of Upgrading to Lightweight Wheels

Enhanced Steering Response

Reducing the weight of the wheels directly affects the steering feel of the NSX. Lighter wheels reduce the effort needed to initiate and sustain steering inputs, resulting in quicker and more precise responses. This makes high-speed maneuvers feel more intuitive and controlled, which is crucial for track driving or spirited canyon runs.

Improved Tire Wear and Suspension Longevity

With less unsprung mass, the suspension components endure less strain during operation, potentially extending the life of shocks, struts, and bushings. Additionally, lighter wheels reduce tire scrub during cornering, which can lead to more even tire wear and longer tread life.

Better Heat Dissipation

Many lightweight wheels feature designs that optimize airflow to the brakes, helping to dissipate heat more effectively. This is particularly important during track sessions or aggressive driving where brake temperatures can soar, potentially causing fade or reduced performance.

Installation Tips and Maintenance for Lightweight Wheels on the NSX

Professional Installation and Balancing

Given the precision engineering of the Acura NSX and the critical role wheels play in handling, it is highly recommended to have your new lightweight wheels installed by a professional. Proper torque settings for lug nuts, correct wheel balancing, and ensuring the wheels are free of defects are essential to maximize performance and safety.

Choosing Compatible Tires

Lightweight wheels should be paired with high-performance tires that complement the NSX’s capabilities. Consider tires designed for enhanced grip, responsiveness, and durability, such as Michelin Pilot Sport Cup 2 or Pirelli P Zero models. Proper tire selection ensures the wheels and tires work harmoniously to deliver optimal handling.

Regular Inspection and Care

Lightweight wheels, particularly forged aluminum, require routine inspection to detect any cracks, bends, or damage from road hazards. Cleaning your wheels with appropriate non-abrasive products helps maintain their finish and prevents corrosion. Avoid harsh chemicals that can degrade protective coatings.
