dont get to drive 300 much,but noticed rear end very loose when i do get a ride,i have adjustable struts all round and on way to japfest a load of supras came flying up so i fancied annoying them as they wouldnt let me be ahead of them so like a wasp i kept leading them and annoying them it came to a head on flat part of m4 nothing in front but had to ease off as rear end seemed like it was bouncing around which scared jesus out of me,255/40/17 on back not best tyres have to admit on the rims? its like coming off a bend or roundabout alittle beans and back end bouncing

same problem as me , mine is shocks !

only done 200 miles since last mot last sept they passed fine?

could still be weak mate, Also your subframe bushes could be shot?

im assuming rear at full stiffness as never changed it since i bought it 5 years ago maybe i should try making it softer dont know what setting its on its got that 4 colour sticker on bolt thread.how do you adjust them taking it flat end screw driver clockwise or anti?

how do i check the bushes?wouldnt that fail mot?
