http://www.polybush.co.uk/polybush-gradesmy take though I know others have differing opinions...
I have blue in my panhard bush as per recommendation on here and have no problems with them though I know panhard bushes need a frequent change (soon as on set of death wobble becomes evident). Also have blue bushes on the rear anti roll bar - not really needed but I was flush. Everywhere else I got another lesser brand(s) (orange britpart) - other than not as good quality for the initial fitment for some of the bushes I have had no complaints for 3 years use - doubt they'd suit a competition vehicle though. I intent to replace with polybush brand or better in dribs and drabs as and when wear is evident. I do know that come MOT time the guy see's polybushes and is happy enough without going further which speaks for itself.
