From Scan to Carbon: The Development of APR Performance GT2 AeroMirrors

At APR Performance, every product begins with a question: How can we engineer this better than anything before it?
The development of our GT2 AeroMirrors is a perfect example of that philosophy in motion—where digital precision, real-world testing, and aerodynamic science converge.

Precision Starts with the Vehicle

Our mirror development begins long before carbon fiber enters the picture. Each vehicle is digitally captured using high-resolution 3D scanning, allowing us to precisely record mounting points, door contours, and surrounding surfaces. This ensures an OEM-level fit that integrates seamlessly with the vehicle’s original design.

The scan data is then converted into a clean, accurate CAD model, forming the foundation for everything that follows.

Design, Refined Digitally

Within CAD, our designers refine proportions, sight lines, and adjustability while balancing aesthetics, structural integrity, and aerodynamic intent. Multiple design iterations are evaluated virtually, enabling us to optimize mirror housing shape and arm geometry before any physical part is produced.

This digital-first approach allows us to resolve design challenges early—saving time while improving performance.

Prototyping Meets Reality

Once a design direction is established, rapid 3D-printed prototypes are produced and test-fitted on the vehicle. These real-world evaluations focus on:

• Driver visibility and ergonomics

• Clearance and adjustability

• Vibration control and stability

Physical testing provides invaluable feedback that simply can’t be simulated alone.

Aerodynamics Drive the Final Form

Insights from prototype testing are fed back into our CAD and CFD (Computational Fluid Dynamics) workflow. This iterative loop allows us to refine airflow behavior, reduce drag, and ensure the mirror’s shape contributes to overall aerodynamic efficiency rather than detracting from it.

Carbon Fiber, Done Right

With the design finalized, the GT2 AeroMirror transitions into carbon fiber production. Precision molds, controlled carbon layup, and carefully managed curing processes ensure a final product that is:

• Exceptionally lightweight

• Structurally rigid

• Aerodynamically optimized

The end result is a carbon mirror whose form is dictated by airflow analysis—engineered from scan data to CFD, prototype to production.

Engineered With Purpose

The APR GT2 AeroMirror is not a cosmetic accessory. It is a purpose-built aerodynamic component, developed through a rigorous engineering process and finished to the standards expected of APR Performance.
