AMG GT S
The owner of this AMG GT S already had an aftermarket GTR-style wing, but that wasn’t enough. Solutions exist to extend factory GTR wings above their original mounts, but the subtle differences in this particular example meant that a bolt-on approach was not an option.
A pair of risers lift the existing carbon wing up and rearward, starting with the original mounting points. No GTR parts, no cutting, and no improvising required — the wing the car already had, repositioned to work the way a wing should.
THe Problem
From the factory, the GTR wing sits low and close to the deck, in air that's already broken up by the body ahead of it. Raising it should be a bolt-on, but in this case, nothing off the shelf exists to lift this particular wing as intended.
Every dimension starts with the car. The wing and the trunk were 3D-scanned with reference targets on the surfaces so the scan comes back accurate to the part, not close to it.
What comes out is exact. There is no tape measure in this process. The geometry is captured, not estimated.
THE DESIGN
From the scan, a riser that raises the wing roughly 100 mm and sets it rearward at a fixed angle. Higher and further back puts the element in cleaner air; staying inside the rear bumper line keeps it true to the body.
Prototyped in PET-GF — stiff, dimensionally stable, and cheap enough to verify fit on the car before committing. The final risers are printed in aluminum. The prototype proves the geometry; the metal carries the load.
THE PART
Fitment was confirmed across two prototype rounds — the second sitting slightly lower and further back than the first. With that locked, the final risers were produced in aluminum. The design and manufacturing processes were carried out with both structure and style in mind. The parts needed to be lightweight, visually appealing, and structurally sound.
They bolt to the car's existing hardware, follow the line of the trunk where they meet it, and carry the altrd mark on the face. A one-off solution that brought this owner’s vision to life.
