For those that may be interested, one of my rear shocks had seized. Didnt fancy the stealers prices so have fitted bilstein b4 all round, with standard killen springs on the front and heavy duty killens on the rear to help with the towbar and lpg tank.
The handling is transformed, each to their own but i fully recommend it to anyone who is considering upgrading. The mot station said it failed on two front bushes and they had to fit new wishbones, at £70 each plus labour. (which with two tyre fittings came to £200 labour alone) I argued and told them to press new ones in as i didnt want pattern wbs. They said the labour would be more, so i gave in in the end but very dubious about this. Hmmm. But hey the car is riding great!
