The business of tuning Porsche sports cars is a big one. It can also be an expensive one depending on where you go. Still, Porsche owners, particularly those who have the 911, have shown little hesitation in giving their sports cars these programs, partly because of the need to unlock the car’s full potential and partly because, well, they can. One tuner that has proven its worth in this regard is TechArt, the same German aftermarket company that recently gave us this beauty of a tuning kit for the Porsche 718 Cayman. Seems fitting then that with that upgrade comes another one for the 911, and it’s one that most of us are all too familiar with. Ladies and gentlemen, this is the new Porsche 911 Turbo S GTStreet R by TechArt.
