1st gen odyssey - coilover custom springrates?

my friend just got a 1st gen odyssey, and i started showing him pictures of fixed up ones, and he loves it and wants to lower it.. 

but..

we cant seem to find any type of coilovers or springs for it, so we're thinking maybe to just purchase a sleeve type coilover setup with custom spring rates for it, trying to keep comfort in there aswell.. but then we're looking to have the rears slightly stiffer since it's a haul'ing vehicle for engines and stuff too.. 

what would you guys recomend as far as spring rates go for coilovers?

thanks  :D

Try to find something comparable to it's weight, then go from there.

There's always the air suspension option :D

What's his budget...?

i think his range is around 400 or so..

I am using the Tein high tech spring, and I highly recommend it.

check out the tein web site. They have all spring rates listed with their suspension for RA1.
