been reading your ideas for months and thought I had better say Hi.
Going to replace my arb bushes and plastic collars with new rubber bushes and steel shaft collars but reading all the info on this forum I am starting to wish I had gone for poly bushes. Still I believe once you have drilled the rivets and fitted the bar, future replacements can be done without dropping the subframe. I will see how it goes this weekend.
Do the polly bushes make the ride any harder /less comfortable?
