Did I hit the deadline of what’s possible with a e92 M3 6speed manual running on street legal tires with a stock engine?

Really looking forward to see when the F8x’s will come close.
Up to now many nice builds are driving around but
none of the cars is really fast.

Done and recorded and data logged – BTG – Bridge to Gantry of 7:05min

On slicks as well as with a 4.4 or 4.6l stroker for sure even more is possible.
But as the BTG time is always a comparison for street legal cars
driving during Touristenfahrten or Trackdays we keep using it to have
comparable numbers.
For those who are interested:
BTG 7:05min is ~7:29min Full lap and ~7:25min Sport Auto Supertest Time
