the 98 200SX is the same car as the 99 Sentra, except for the whole 2 door thing. likewise the 98 200SX SE-R is the same as the 99 Sentra SEL. sometimes when purchasing products for my car i have had to order them for a 98 200SX SE-R, just so the vendor doesn't get confused. i'm not sure that the 95-97 springs will work though. maybe brian @ courtesy could tell ya or some other knowlegable folks on the forum.
