I don't like the polybushes on the rear of these style wishbones. The poly is just to hard and doesn't flex like the original is designed too. Whoever designed them obvioussly wasn't thinking about how the wishbone was designed to move. It either needs a spherical bearing or as you say an lcr style full rubber mount.
You can get race rear wishbone bushes which in essence are rose joints, but very solid ride
nice just done mine it grips better out of corners well worth while! 20 quid well spent!
