Ok, i changed my bushes, although mine really didnt want to come out at all,lol, @£25 each it was well worth it, the difference is outstandidng.So much tighter and more precise.
Tokk me an hour and a half to get the one done and half hour to do the other one from start to finish, the bloomin things are a soft alloy and fret in place.
Tip for anyone doing this, make sure the bushes go in with the right orientation, the small cutout towards the antirollbar.
