Looking at getting would new tca's fitted with rose joints what are the advantages over poly bushes?
there's no give in them at all, they are solid.
they are not exactly solid, usely they come in three flavours :)
THESE (http://www.strongflex.eu/en/323-volkswagen-polo-i-ii-75-94) guys arent expensive and read good reviews about them.
GOOD COMPARISON (http://www.strongflex.eu/en/content/6-red-or-yellow) between the 3 types they make.
those are poly bushes, not rose joints. A rose joint is a metal spherical bearing.
poly bushes do as you say, they are just stiffer then the standard bushes.
i noticed hahahaha, i answered the wrong way round :P
yeah I see what's happened, I meant rose joints in my first post near the top!
ah well, some free info, always nice :)
