2015-2020 BMW F80 M3 / F82 / F83 M4 - VRS Style Carbon Fiber Diffuser + Undertray

Product Description

Take your F8X BMW M-Series to the pinnacle of track-inspired styling with the NexaNovo VRS Real Carbon Fiber Diffuser and Undertray. This two-piece system is engineered specifically for the 2015–2020 F80 M3 and F82/F83 M4, replacing the factory rear trim with a massive, multi-dimensional aero component that defines the rear of the car.

Key Features

• Aggressive V-Style Aero: This high-performance kit features an ultra-aggressive center diffuser with deep vertical strakes, paired with an extended lower undertray. The design creates a "boxed-in" motorsport look that adds significant visual width and depth to the F8X chassis.

• Authentic 3K Twill Carbon Fiber: Hand-laid using genuine 3K 2x2 twill carbon fiber weave. This isn't a print; it is a high-strength, lightweight structural component finished with a mirror-deep UV-resistant clear coat to prevent yellowing and protect against exhaust heat.

• Functional Underbody Management: The extended undertray isn't just for show—it smooths the airflow exiting the rear of the vehicle, reducing turbulence and enhancing high-speed stability by creating a more efficient low-pressure zone.

• Signature M-Series Fitment: Precision-molded for an exacting fit on:

  • BMW M3 Sedan (F80)

  • BMW M4 Coupe (F82) & Convertible (F83)

  • Years: 2015, 2016, 2017, 2018, 2019, 2020.

• Lightweight & Heat Resistant: Designed to withstand the intense thermal cycles of performance exhaust systems. The carbon fiber construction offers an incredible strength-to-weight ratio, ensuring the aero kit stays rigid even at track speeds.

• Comprehensive Installation: This system is designed to replace the OEM diffuser. It utilizes factory mounting points combined with provided mechanical hardware to secure the undertray. Professional installation is highly recommended due to the size and complexity of the two-piece assembly.

Product Specifications

FAQ:

Will this fit with my aftermarket exhaust?

The V-Style system is designed to accommodate most popular 90mm and 102mm quad-tip exhaust systems. However, extreme "straight-pipe" or custom wide-exit setups may require minor trimming of the undertray.

Is all the mounting hardware included?

Yes, the kit comes with the necessary bolts and brackets required to secure the undertray to the main diffuser and the vehicle's subframe points.

Do I need to remove the rear bumper for installation?

While not strictly required, removing the bumper makes the alignment and securing of the undertray significantly easier and is recommended for the best results.

How much lower does the undertray sit compared to stock?

The undertray sits approximately 1 to 1.5 inches lower than the factory plastic trim, providing a much more aggressive stance without making the car impossible to drive on the street.
