i didnt fit the suspension myself as i had a garage have the fun and hassle of dealing with the old bushings, and then setting ride hide to specs 
but… i have since fitted the rear strut bar myself. the room is tight by the rear bulkhead but its just 2 bolts per shock tower. each side has room for a breaker bar on one, and the other needs the ‘double spanner’ extension for the leverage.
also to confirm above… i double checked the weights of the rear and front anti-roll bars - they are indeed correct.
(i had forgotten how silly then the rear is! smaller than my little finger. )
