You should consider getting some aftermarket shocks so that the OEM ones don't wear out too quickly with the lowering kit.  You can get any performance shocks you like, most say if they're compatible with a lowered cars or not.  You're OEM shocks won't like bottom out and stay there, but you'll feel them get progressively worse over time and then the car will be bouncy.  Ever see a Honda with cut springs?  BOING!

Hey Spyderman, how are the Sportlines?  I always hear bad things about them for the spyders, but i've never actually talked to anyone with them.  They aren't bouncy or anything, are they?  Everyone always recommends the Prokit, but i dunno.  They sound good, but are they too low?  A pic would be cool.
