Rear toe and camber is a critical angle on these cars with such big feet. There is a toe change as they move through their travel. It needs to be very even from one side to another and that needs to be checked on a good four wheel alignment machine by someone that knows what they're doing and knows independent rears. Your shocks could well be even but if you know a local racer checking corner weights on scales will be a useful number in diagnosing this too.
