Amongst other problems with my new Williams I am not happy with the directness of the front end. The ARB bushes certainly seem well past their best, with cracks in the rubber. If I replace these am I better off going for OE bushes (Do Renault still sell these? Do GSF do a set as I presume they would be half the price there) or do I fit the Powerflex set which should last longer and remove further slack from the system?
