So I have visited Nurburgring, trying to drive in the manner occasion mandated.
The very next day I?ve noticed oil stains on the back bumper. Also amount of oil went from full to minimum around same time.
When I got home I?ve inspected from underneath using the inspection camera. Worth to mention that just before the trip and it was Eurofest Belfast trip, about 4200 miles, I had main crankshaft seal and gearbox seal replaced.
There are oil stains on the bellhousing, mostly on the driver side, some on the gearbox and oil pan. No oil in the clutch and flywheel area.
There are neither visible oil leaks, nor oil stains on the garage floor.
Obviously I did drive on the Nurburgring in the exuberant and enthusiastic fashion. And it was pretty hot day as well.
It looks that the way I drove made some amount of oil to emigrate from the engine and wander outside. No permanent leak exist as such.
I have some sneaky suspicion where the oil came from. Will keep quiet for the moment as not to suggest anything.
Any and all ideas and suggestions are welcomed. Perhaps someone experienced something similar and has some definitive answer?

Are the cam endplates leaking? They are known to leak - I have mine replaced with billet pieces w/new gaskets.

They are not superclean but I don't think so.
Bottom part of the engine has the signs of the fresh oil.
I am thinking high speeds and tight bends combination forced some oil out. But where? Which way would be the question.

No comment on your problem. Are your wheels and tires stock?

My guess is the left side valve cover. Sharp turns and heavy braking caused oil to pool at the front corner and leak.
