3D Design has firmly established itself as one of the most respected names in the BMW tuning world. Known for delivering some of the highest-quality aero and styling packages for previous-generation M5 platforms, that same level of craftsmanship and engineering carries over seamlessly to the latest G90 M5 Sedan and G99 M5 Touring.

The new 3D Design full carbon fiber rear diffuser is constructed from premium pre-preg 2×2 twill carbon fiber and truly sets itself apart from the rest of the market. Designed with clean OEM+ body lines, the diffuser enhances the rear of the M5 with a more aggressive presence while preserving the factory design language. Installation is equally well thought out, utilizing factory-style mounting clips and including a full carbon fiber replacement tow hook cover for a complete, no-compromise finish.

The diffuser’s side fin design flows naturally with BMW’s rear bumper contours and aligns perfectly with the winged 3D Design side skirts, creating a cohesive and unified aero package from front to rear. As expected from 3D Design, fitment, surface quality, and overall execution are exceptional.

Who Is 3D Design

Founded in 1998 by three BMW-focused designers with genuine motorsport backgrounds, 3D Design was built on a clear philosophy: create BMW parts they would personally use themselves. From circuit to street, every product is developed with the end user in mind. In 2006, the leadership team expanded to include industry veterans with over a decade of experience in product development and marketing, while maintaining the brand’s original mission and attention to detail.

What Makes 3D Design Different

3D Design does not chase volume or trend-driven styling. Instead, they focus on surface development, precise fitment, and how each component integrates into the overall driving experience. While digital tools assist in development, final designs are refined through traditional hand modeling, allowing subtle shapes and transitions to be perfected beyond what simulations alone can capture. The result is aerodynamic components that integrate like OEM, exhaust systems with balanced sound and flow, and chassis parts that feel purposeful rather than overstated.
