best of luck with that, in a way i hope it is the bearings, saves you wondering and putting up with it. yea cupra r 225, and your right they are different, the whole lower arm assembly is different, the drop links screw into the wishbone by the look of it but mine are seperate, and the ball joints are different and go off at a slightly different angle. it surprised me when i tryed fitting a cupra arm to a mates cupra r ( under his instruction)
