2025 BMW M4 CS

Completed August 2025

Project Overview:

To take this already impressive platform to the next level, we outfitted the M4 CS with a series of carefully selected aftermarket upgrades. Most notably, we installed the ADRO Swan Neck Wing, a functional and visually striking aerodynamic enhancement that increases rear downforce and provides greater high-speed stability without compromising the car’s sleek lines. Up front, the addition of Burger Motorsports Front Mount Intakes improves airflow to the engine, enhancing throttle response and maximizing power delivery, especially under aggressive driving conditions. To tie the performance package together, we fitted a Milltek Sport Midpipe, which not only reduces backpressure for improved exhaust flow but also adds a deeper, more pronounced exhaust note that matches the car’s motorsport pedigree.

The result is a uniquely tuned M4 CS that balances OEM engineering excellence with purpose-driven modifications. It retains the refined aggression of the factory model while delivering a more visceral, connected driving experience—perfect for the enthusiast who demands both form and function.
