It was a modified car afaik. Not for sale to the public?
Just put an M2 on a dry day on Sport Cup2 tyres and one of those BMW engineers/testdrivers can manage >10s off of the 7:58 I'm sure. Just like the tyre choice of the M4CS(Sport Cup2) makes 90% of the 7:38, not the rest of their marketing 'nonsense' of losing weight lol.
It's a great achievement etc etc, but at the end of the day you still drive an ugly FWD as a daily. That's not fun in real life IMHO
(it sometimes rains overhere you know) , been there done that
