I like the looks of that car. Based on my personal experience with 912's, I can confidently say that car rides like crap and the handling suffers as well. He's got the ride height set up to the point he's taken all the suspension travel out of it in one direction so the car will, and does based on the video, bounce over bumps rather than absorbing them.
I wonder if he bothered to corner balance it.
Nice execution on the body work for sure though, as it is a looker.
Here's a picture of my old 912.
