rear beam bushes worth fitting poly bushes

Right the bushes on the back of my mk1 gti where the beam is attaced to the car are shot

I have a set of bugpack poly bushes for this area in a kit ive got

now my question is are they worth fitting over standard as ive heard they can cause the car to be a bit ar– happy

due to not having any give

any enlightenment on this subject would be greatly appreciated

thanks

Ive had them on myn for 2 months now and they seem to be fine. Back end doesnt twitch, probably due to the 1.1 slug under the bonnet

had em in my cabby for a couple years, no problems at all. reason i did it is that i found a complete mk1 bush kit for same price as oem rear bushes
