The "old" one or the "new" one?

One other thing that no one has mentioned yet is the increase in unsprung weight. It is very noticeable that the rear unsprung weight is much more than the front just by going over a speed bump. Not sure though if I can tell a before/after difference. However, there is no doubt that it is worse, just going by the weight increase...
