Vorsteiner VRS Glossy Carbon Rear Diffuser for F8x BMW M3 and M4 GTS [4001BMV]

Vorsteiner VRS Glossy Carbon Rear Diffuser for F8x BMW M3 and M4 GTS [4001BMV]

The Vorsteiner VRS Glossy Carbon Rear Diffuser for F80 / F82 BMW M3 and M4 GTS is crafted using an aerospace-grade autoclave process that produces a component 20-30% stiffer and stronger than traditional wet-lay methods. Made from a composite of unidirectional, 1×1, and 2×2 weave carbon fiber, the diffuser is vacuum-formed to extract excess resin, resulting in optimized weight and enhanced structural rigidity. Designed to align precisely with OEM panel gaps and body lines, it delivers a seamless fit and a premium, motorsport-inspired aesthetic.

VRS Program

• Vorsteiner’s VRS Program for the F8x BMW M3 and M4 presents a cohesive range of carbon fiber enhancements designed to elevate both styling and performance through motorsport-inspired aggression and precise OEM-level fitment. The collection features a standard 2×2 Front Spoiler and a more pronounced GTS-V Style Front Spoiler, complemented by matching rear options that include both a standard Rear Diffuser and a GTS-V Rear Diffuser. Side profile updates are provided by the GTS-V Style Side Blades, while the rear silhouette is completed with Vorsteiner’s signature Wing Blade, offered with Raw Aluminum or Matte Black Uprights for a custom-tailored finish. Every component is constructed using premium pre-preg carbon fiber, delivering an ideal balance of strength, lightness, and visual presence in line with M performance.

Stronger & Lighter

• To achieve superior aerodynamic functionality, Vorsteiner employs aerospace-grade autoclave manufacturing across its carbon fiber lineup. This advanced process uses resin-infused, vacuum-formed carbon fiber, producing parts that are 20-30% stiffer and more durable than conventional wet lay-up methods—ensuring improved strength, finish consistency, and structural integrity.

Aero That Fits Like A Glove

• A calculated blend of unidirectional, 1×1, and 2×2 carbon fiber weaves is used to enhance rigidity while minimizing overall weight. Through vacuum-forming, excess resin is removed, preserving the structural core and reducing unnecessary mass, resulting in high precision and a premium finish. Each piece is sculpted to align with factory body lines, offering OEM-quality fitment with elevated visual and aerodynamic appeal. Vorsteiner’s proprietary production standards reflect the brand’s dedication to uncompromising performance, precision, and design excellence.
