Traction control issue in frustration in GT3

I am with you a 100%!
I just quit the GT3 Class in my own racing community just because of the problems you described.
I have driven almost all the other cars in R3E and no other class behaves like "something" is happening in the electronics of those cars, but I can't figure out what it is. The other guys in my community don't seem to get what I am on about.
I can not believe that this is "get real"

I like driving the Porsche GT3 Cup which has TC and ABS as well. But this feels like I suppose it should.
I am a sim-racer for years, but the R3E GTR3 leave me..
