Continuing the celebration of our 20th anniversary we decided to redesign a modern version of the V-CSL Carbon Fiber Program for the BMW E46 M3. The new V20 program incorporates dual acorn shaped snorkels into the front bumper with a redesigned one-piece front spoiler.  The Hood is double sided Carbon Fiber and features raised left and right vents to extract hot air out of the engine bay. The rear diffuser now features dual diffuser elements increasing airflow across the diffuser.  The V20 will be a limited production run of 103 units, paying homage to the impressive horsepower per liter that the BMW E46 CSL delivered. Please see the below outline of all the V-CSL Components. Each piece is crafted using our 1X1 Weaved Pre-Preg Autoclaved Carbon Fiber and produced at our California facility.

  • V20 Front Bumper with 1 Piece Spoiler

Vorsteiner Technology

Not “Good Enough.” Engineered to Lead.

At Vorsteiner, “good enough” isn’t part of our vocabulary. Every aerodynamic component is engineered to push boundaries-not follow them. Using a state-of-the-art aerospace-grade autoclave process, our carbon fiber parts deliver exceptional rigidity, structural integrity, and surface finish.

The result? Aerodynamics that don’t just look advanced-they are advanced.

OEM Fitment

Factory Precision. Elevated Design.

Our proprietary manufacturing process allows for exceptional control over tolerances, fit, and finish. Each Vorsteiner component is engineered to align precisely with factory shut lines and body contours—delivering an installation experience that feels OEM, but looks unmistakably premium.

This isn’t “close enough” aftermarket fitment. This is carbon fiber that installs cleanly, fits perfectly, and elevates the vehicle’s design language.

Stronger and Lighter

Less weight. More strength. Zero compromise.

Vorsteiner components are manufactured using resin pre-impregnated, vacuum-formed carbon fiber—technology reserved for high-performance aerospace and motorsports applications. Compared to traditional wet-lay carbon fiber, this process produces parts that are 20–30% stiffer and stronger while eliminating unnecessary weight.

By vacuum-drawing excess resin during curing, we remove what doesn’t contribute to strength—resulting in lighter components without sacrificing rigidity or durability.
