I installed my blitz a while back when I had it, its not very tough if you get a blitz that is of good quality and construction. The tough part will be aligning and drilling the holes for the screws especially the ones connecting to the front edge of the fenders (two on each side, but the holes on the top center should be easy if you eye ball it. Also be prepared to remove the front reinforcement bar in front of the radiator once you install the blitz you won't be able to put the bar back on because it wont fit with the design of the blitz. Also be aware that the edge of plastic wheel well won't fully reach the blitz it doesnt curve inward like the stocker.
