Hey Greydog,
Your response is much appreciated. Yes the car has been fitted with a set of coilovers unfortunately. I asked a Mechanic in Belfast and they seemed totally oblivious to why this has happened or how to fix it (morons over here unfortunately).
I was hoping I can revert to original rear springs without a massive job and heard about top strut mounts can fail when fitting these stupid coilover kits.
I have money to cover repairs on the car, but don't want to be spending massive amounts on this one issue if I can avoid it?
