Looks nothing out of the ordinary to me, berg arches and wider wheels yes - can get from variety of suppliers in Germany, chassis wise, almost cup spec with a box frame but hasn't gone indepth (if you get what i mean), such as adjustable wishbones and frame etc etc. Note under chassis run fuel lines and brakes lines still and also the ARB lowering blocks

But...
Looks Awesome!!!
Thats what mine would have looked like should it have been finished.
