Sliding is more understeer, corner entry - in this TT I noticed quite a lot of improvement when I took the last corner a bit easier with less throttle, thus didn't induce the understeer. I'm pretty sure I start turning while still too fast for some corners (true overall, not just this TT), for example the hairpin after the winding front straight before heading to the tunnel. I feel that I take the hairpin after the tunnel in a much better way.
I do encounter sliding and oversteer on corner exit because I'm just too eager getting on the throttle - and spin out, so that mistery is more or less solved

Understeer what really bothers me - just thinking about the Big Willow TT, right after that stupid left loop on the top there's a left hander before heading to the last section, I get some "nice" understeer, as well.
I'm pretty sure I saved both replays, so I will take
@KAlex122's suggestion (Vielen Dank!) and try to post them.
