Default cosworth outer trailing arm bush on 6 degree beam

hi,
my 6 degree rear beam has rose jointed inner trailing arm bushes and on the outers black powerflex poly bushes,

arm moves full travel free enough,

would standard outer bushes be better?
can understand on standard arm why oe bushes would be better,just wondering if same applies with a 6 degree beam?

hi
you shouldn't be running bushes at all on a 6 degree beam ,when you adjust inner rose joint its forcing the outer one out of line ,it should either be rose jointed or standard bearing

On a 6 degree beam the mounting points are not in line anymore, so when the arm moves it deforms the bushes. A spherical bearing just rotates slightly.

that makes sense right enough,
was standard bushes but ended up knocking so popped polys in,
have 1 new bush will try get another,
or could I use a ggr bush one side and standard bush on other?
probably be happier if both were the same tho,
many thanks
