Do you have a big front sway bar? If not I would add one.

The pic of the alignment is a little hard to see, if I read it correctly I would add more toe in in the back. Somewhere around 1/8 in. to ¼ in. total toe in. I think in inches not degrees for toe.

 

after 200km/h if you're feeling uneasy then that's about right. That's "normal"

What you want is a wing.

 

That alignment doesn't look good in the least. Side to side you are off by over .5degrees on rear camber and there is no symmetry.
Look for UK alignment specs and have them set to that.

 

wing and wider tires

 

any better now??
if i take of the rear sway bar??
or if i make stiffer the rear subframe??

thanks for the help

the side to side difrent is because i wasnt in the car.. Sent from my iPhone

 

Why different front and rear tire compounds? Street tire front, R-comp rear?

 

i thought that with more grip rear will be better...
but not enought....

The compounds heat up and resist heat differently, which can lead to changing front/rear grip. Especially if there's any moisture.
