imo...
an affordable, adjustable height bolt on coilover will do wonders..
threaded adjustable monotube shock (inverted sucks to adjust with the datsun set up)
weldon threaded tube
non adjustable cnc strut mounts
adjustable height, adjustable dampner settings,
trackable, dailyable, easy
then offer a more serious coilover for the people with those needs.
camber plates
