its pretty "normal" (for a renault) we see it all the time, Renault will probably tell you no
its caused by the bump stop sleve rubbing on the shock, surpising plastic does that to metal
not dangerous
i just feel they drive much better with toe in, its suits my driving style too i guess
we run the 240bhp cup with slight toe in (3deg neg camber)
here's a question
what happens to the wheels when you accelerate??? (apart from the obvious!)
