The Subaru BRZ and its sibling, the Toyota GR86, have redefined affordable sports cars. While these vehicles offer thrilling performance, some owners face challenges with road noise. This article delves into the issues, solutions, and insights from real-world experiences to help enthusiasts enhance their driving enjoyment.

Discover Proven Solutions for a Quieter Ride

Owners of the Subaru BRZ are encountering significant road noise issues, particularly on highways. Various attempts to mitigate this problem have yielded limited success, leaving many seeking alternative strategies. In this article, we explore the underlying causes, evaluate potential fixes, and provide expert advice to achieve a quieter cabin environment.

Understanding the Root Cause

The Subaru BRZ, designed for performance and affordability, often lacks extensive sound insulation. This minimalist approach can lead to increased road noise, especially noticeable during highway drives. DLNBRZ71, a forum member, detailed his struggles with "howling resonance" on concrete surfaces despite trying multiple tire changes and removing certain components. His experience highlights the complexity of addressing this issue.Sports cars typically prioritize weight reduction over sound insulation, which explains why road noise is more prevalent in models like the BRZ. However, the severity varies among individual units, suggesting that factors beyond design might play a role. For instance, manufacturing tolerances or specific road conditions could exacerbate the problem.

Evaluating Tire Options

Tires significantly influence road noise levels. The stock Michelin Pilot Sport 4 tires, known for their high-performance capabilities, also generate considerable noise. DLNBRZ71 experimented with Continental Conti Ext. Cont. DWS06 tires but found little improvement. He then considered Pirelli P-Zero A/S +3 tires, praised for their quiet operation in the ultra-high-performance all-season category.Choosing the right tire size is crucial. A slight increase in diameter, such as switching to 225/40 x 18 tires, can affect fitment and performance. Owners must ensure compatibility with their vehicle's specifications before making any changes. Consulting forums and manufacturer guidelines can provide valuable insights into suitable alternatives.

Exploring Sound Deadening Materials

For those unwilling to replace tires repeatedly, sound deadening materials offer a viable solution. Two primary types—rubber-based mats and foam—are commonly used. Rubber mats excel at dampening vibrations but add weight, while foam materials are lighter and absorb heat effectively. Applying these materials strategically can significantly reduce interior noise without compromising vehicle dynamics.Installing sound deadening requires careful planning and execution. Forum members suggest focusing on areas prone to noise transmission, such as the floor and firewall. Professional installation at a reputable car audio shop ensures optimal results. DIY enthusiasts can also tackle the project by purchasing quality materials and following detailed instructions.

Real-World Experiences and Recommendations

Several Subaru BRZ owners have shared their experiences and solutions online. Zeroptzero noted that the BRZ's lack of sound insulation contributes to excessive noise, especially on concrete surfaces. Disabling piped-in engine sounds improved comfort for some, highlighting the importance of addressing both external and internal noise sources.Alex_W recommended professional sound deadening services, emphasizing that targeted interventions yield better results than random modifications. RZ-1 suggested DIY installation using affordable sound mats, offering a cost-effective alternative. These firsthand accounts underscore the value of community knowledge in overcoming common challenges.

Future Prospects and Final Thoughts

As manufacturers continue refining sports cars, future iterations of the Subaru BRZ and Toyota GR86 may address existing shortcomings. Potential improvements in sound insulation and tire technology could enhance driving experiences. Meanwhile, current owners can leverage available solutions to enjoy a quieter, more comfortable ride.Ultimately, the quest for a balanced blend of performance and comfort remains an ongoing pursuit for sports car enthusiasts. By exploring innovative solutions and sharing insights, the automotive community can collectively advance toward achieving the ideal driving experience.
