I did a rear end resto last year so had the whole lot off and replaced everthing with new ie bushes, anti roll bar links and diff mount, i even upgraded to 4x4 anti roll bar, my m8 who has had many a cossie and now drives a M5 was so impressed with its straight line grip, he said he hasn't ever been in a 2wd cossie with the spec i'm running and so much grip still, it just squats and fucks off . I'm not saying its all down to the shims but more a combo of everything being new it just feels so tight even round corners at speed, rather than a sloppy worn out back end.
