Mine needed most of its bushes replaced, new to the Mk5 I started looking into a kit from my favourite Superpro, but with their kit being £500 - too expensive.
The alternatives of:
Powerflex - nearly as expensive as superpro, limited choice of shore value, but in the past had bad experiences with early failures + their stuff tends to have some weirdness in how they get assemble on the car -no thanks
Problem Solving Bushes - full kit £140, no shore value choice, but heard good things about them in the past so gave them a go.
Yes agree, rear end with all 14 bushes was a complete cockerel of a job, but I learnt how my rear end fits together, dropping the subframe makes life a lot easier.
Have to say for the price the PSB bushes have been great, only one rear arm was a little odd with retaining the old bush outer case otherwise everything was straight forward push out and replace.
Only change in noise was when I added a Superpro dog bone insert that eventually quietened down and now only rattles on rough road surfaces.
Would I do it again - partially - typically after installing the bushes I found out about full Lemforder rear arm kits on ebay that -considering the time spent swapping out old bushes- are really good value - but I would still polybush the front end.
