Yeah, 200sx doesn't have ANY suspension travel. I think the rear will actually hit the bump stops with 1.5 inches of drop. My brother went crazy with some ebay coilovers and took out his bumpstops. It was wheel tucked in the rear and it rode horribly. I mean hitting your head on the roof, horribly. If you want a real lowering setup, you'll have to drop real money. Motivational makes custom mounts and shortened body shocks, but they run $235 a piece. Tein also started making coilovers for B14. They should run $800 a set for the BASIC setup. TEIN is probably your best bet for good ride and low height.

-edit-
WOW, the TEIN basics will do from -2.1" to -3.6" front and from -0.9" to -2.9 rear! A 6k front and 5k rear spring rate should be plenty streetable. That's about twice as firm as stock!
