Given that powerflex have changed to the black series for the outer springpan bush, I'm inclined to think the Lemforder rose joints are the best way forward. The black series bushes are very hard, and there is little compliance in these bushes. I'm not sure if this is a good idea. Both my springpan bushes are the purple series, and have been on for ten years now with no problems, so why have powerflex changed from purple to black?

no idea on that, could just be to shift some surplus..... seeing as the lemforder bushes are cheap enough, I am going down that route

Powerflex not the only polybush producer. Have a Polybush set on my GTV all inner & outers on the lower arms and PowerFlex on the upper wishbones ('cause they were cheep on ebay). The Polybush set come in two different grades of polyurethane (red the harder for spring arms and orange the softer, 3-pairs on shock arm). Polybush are used a lot for Landrovers and commercial vehicles, have alook at their website (Polybush the world leader in Polyurethane Suspension Bushes & Components). Both red & orange are much more compliant than the black Powerflex bushes, no idea how they compare with the purple Powerflex ones.

Had them in for 16k miles only but no problems at all and still look as good as the day they went in.

I bought my complete set from Alfisti.net. Mine was powerflexed in the past but with all black bushes, the springpan inners were too big and jacked in place and the top arms weren't done.

My plan is to replace the transverse arm bushes with purple bushes, replace the inner springpan bushes only and keep hold of the upper arm bushes untill i need them. The bushes that i don't need and any that i remove that are in good condition i will re-sell.

And will this affect the the passive rear steering?
I think uprating the rear ARB too much will definately affect the rear wheel steering. Given that it works on the suspension angle i would imagine both rear wheels would steer inwards towards the middle of the car (increase toe-in) when the whole of the rear is compressed evenly.
