there is alot more to properly lowering your 240sx than just coilovers
honestly if you want it really low just cut the springs dude
the basics will lose all of their suspension travel if you slam them. they aren't double adjustable.
they aren't much better than spring and shock setup, but they are TEIN
OOOOOOOOOOOOOOH
AHHHHHHHHHHHH
TEIN!!!!!!!!!!!
dude , section coilovers go WAYYYY lower than tein's do.
FLT-A2 do also, but you don't have the money for either one of those.
