I'm just looking into rear end solutions, apart from £10 rainbum shims that are a half fix, everything seems to be around the £1000 mark to sort out the crap geometry

As far as I can read into it, basically you need to chop off the two original mounting eyes on the front of the trailing arm, and weld on a threaded portion and put in adjustable eye end rose joints?? and due to the angles they are mounted on the beam, that would give you camber adjustment with the inner eye, and toe adjustment with the outer eye???
Would the car benefit from solidly mounting the beam, as opposed to using the great big polly bushes in the beam to car mounting bracket?
