Put the stock front springs from my Miata on the rear struts of the Sentra to raise it up to a usable height, then cranked up the front coilover sleeves to level it out. Much more usable, still rides like shit.
Horrifyingly, the lugs nuts have been on the car backwards this whole time.
Plans for suspension are to buy a set of stock shocks and some 220/200 # front/rear lowering springs, then get a beefy rear sway bar with poly hardware. Should sort out the handling quite well.
