I have the FMS 'b' springs, which, along with shocks, made the car handle enumerately better than the 11yr old stock setup. The 'b' springs are fairly mild (425/550 front 200/300 rear) progressive springs, the 'c' springs swap the fronts for 660 static rate springs. The springs lowered my 90 convert. about an inch, maybe more, and there is a little bit too much outward cant of the wheels, but I haven't gotten CC plates yet. You only know if you need CC plates after youve done it.
