Thanks for replies...
Of course i realise the rs200 is special (superior in fact! :D sorry lexus owners!)
unfortunately i dont know anyone with either an is200 or rs200 so
if i drove one i might know whether its a 'normal' sensation i'm feeling,
maybe i'll call into a dealers or go to kerry for the day!
i've had the rear subframe, upper and lower arms, bearing, drop link, wheel-
all replaced on one side(these had to be done), so i'm paranoid there's something else
wrong.
It has been suggested here that the lower ball joints can cause a similar effect....
