Hi Nik,
I am from Düsseldorf as well ... I have been frequently at the Bilster Berg ... you might have seen me there. Matt black Exige ...
1:55 is were I am with the EX460 on Michelins ... if I look at my data another 2s faster should be doable on Trofeos... my best with the V6 CR stock already was a 1:57 on Trofeos... anything below 2 min is pretty fast there imho ... ? ... its a pretty challenging track ... crazy to see that I was proud of a 2:05 a little more than a year ago and now I am unhappy with not having driven below 1:55 ...
Re noise: my exhaust is stock and its close to the limit ... yes, the Exige is loud ? ...
I got black flagged / warned there in the past but it usually works but it also depends on the event you go to as you probably know. Worst case you can short shift or lift ...
Let me know if you have questions also happy to share data if you run AIM as well and if you share yours ?...
Cheers
Norbert
