GW9-904 Magnesium Monoblock - Vorsteiner Wheels Wheels

In Collaboration with Gunther Werks

Magnesium alloys have a slightly better strength-to-weight ratio than aluminum alloys.  By using magnesium wheels instead of aluminum, the weight of the wheel can be reduced by about one-third.

Additionally, choosing a metal processing technique like forging instead of casting can further improve the strength-to-weight ratio.

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.
