Concerning the front coilover kits for a-bodies... because of their "bolt in" nature they are less than ideal and in the case of QA1 (at least a while back when I considered it) there really aren't any springs available that are heavy enough to do the job right. Also, because the spring sits against the spring perch up in the frame and the shock swivels on the upper bushings the spring induces some sideloading on the shaft and shock body because the spring is working against two different points of reference rather than against the shaft and the body only. If you wanted to do coilovers up front do it RIGHT and mod the upper frame mount with a double shear setup to hold a true coilover (i.e. one with the spring seated on the coilover body itself and not against the frame) with a rod end for the upper end of the coilover mount, similar to what DSE does with their coilover conversions for stock F-body subframes.

An easier and cheaper solution is to use the adjustable spring spacers with 9.5" x 5" circle track springs and standard shocks. I've been running that setup for a while now and it works very well for not much money, plus the springs are cheap so you can keep an inventory for fine tuning.
