if its just a family car just get king springs, will be a nice soft ride, but it wont have any performance advantage for better handling.
i've got BC racing type BR coilovers in mine the s13 model and handle fine if your after better handling(not comfort) i'm running 10kg front 6kg rear , you'd run 8kg fronts if you have a SR20 . they go low and stockish height for rwc, 30 way damper, base height adjst and camber tops for 1.3k to my door
not sure why this is being disscussed tho parts thread clearly states s13 suspension (with the exception for front sway bar) = a31
