a rear knocking when travelling over small potholes is now getting worse and I assume its the rear anti roll bar bushes. Whilst the mechanic is under there, is it worth changing anything else at the same time ? Other bushes etc ? I don't really want to change one part only to find out it was something else. Each of the bushes etc are only a few quid each, so maybe better to change all at once ?  RR Sport Supercharged Vesuvius Orange 4.2 V8 First edition

Prefer RR Vouge S/C but they don't do Orange !
