Dont go buying ebay ones if you can help it like i said courtenay sport do the kit for our cars and i have these fitted and can honestly say they are top notch.
The rear end on vectras can be adjusted for track/toe so bearing that in mind if you have a dodgy rear end :silent: or the trailing arm bushes are shot there will be a good chance your alighnment is out and going by your tyre problem that kind of doubley proves it :wink:
So if you go for it and change them wich will be a good improvement and also get the other parts done you think are at fault make sure after your done to get the alighnment done all round.
After that it should be as good as new :thumbup:
