the apex'i n1 coilover is in the 1500 range
reason= dampening adjustable
the apex'i WS(world sport) coilover is aroun 850
it is a non-dampening adjustable coilover, only ride height
the WS coilover is comparable to the one mentioned above
another thing that i really like about the apex'i coilovers is you can get springs with different spring rates threw apex'i for you personal taste
i've seen the different springs offer at
www.horsepowerfreaks.com
i dunno if anyone else offers different spring rates like apex'i
i know apex'i is good quality
