Create a vintage-style technical drawing of a Porsche 911 GT3 on aged paper with an upper view and a frontal view, featuring detailed line work reminiscent of classical engineering sketches. Surround the drawings with handwritten notes and annotations, including measurements and observations about the design and engineering. Introduce small creative touches, such as unique styling elements or slight modifications in the aerodynamics, while preserving the iconic essence of the 911 GT3.
