Anyhow i really appreciate your help and i will follow up on that website to see what can i find there.

IIRC the actual thread ran along lines you say above, people blaming and claiming that various components solved the issue - one even claimed it was due to wear of the lower front wishbone ball joint. The common thread being making the suspension movement less, either by shorter components, running only in Sport mode, software upgrade, or by stiffer OEM components, ie anti-roll, bushings, etc . However, there was no common consensus of success until a guy came on and claimed he'd found the holy grail. He'd contacted a team in Germany, who he knew were seriously racing V70 R's, and stated the issue and asked for advice. It was these folks who came back with the figure of 0deg total rear toe..
I have subsequently read, (But I'm not 100% sure of my facts here) that the "Hop" is due to the change of -ive/+ive toe as the car turns a corner and encounters a bump. By changing to 0 deg this change from a -ive to +ive toe is eliminated, as your toe technically can be described as already +ive hence the side hop is reduced/eliminated. ( I can't remember which direction the change runs, but that was the explaination I read.)
My car had its rear suspension changed to 0 deg total rear toe, and the change in its side hopping manners was immense. I do still experience it, but never in Sport mode, and only rarely in comfort mode, where to be honest it does catch me out, not expecting it as its so rare now.
BTW That same site has/had a fascinating thread - dozens of pages , about the collar gear in the bevel gear, if you like techy stuff.
