that small bar looks like a sway/stabilizer bar end link.

Couldn't tell you how they did the rest of it, although it really wouldn't be that hard to have a shop (typically race car/rally car shops will be able to do this for you) order biltstein shocks that are the correct length and flex, and then custom valve them to fit your application. use some threaded mounts for a coilover perch, and take some weights/measurements and you have a fully setup car.

Would probably end up being under 2 grand as well.
