do a search, I don't think anyone is running those springs. haven't honestly seen any reviews on them. personally, I say, why not find a set that are tried, tested, and true. i.e. Goldlines or any Eibach kit. there are some people running Canuk Motorsport springs and like the drop on them too.
the main thing is to go for the struts. don't cheap out and get factory replacement ones, they'll blow out extremely quick on you.
Look up the01cav, he's the only one I've ever known to use them, I'm sure there are others though.

if its a 1.8 inch drop why not just go with the Eibach pro kit?
pretty sure Owen ran Sprints on Reds
I have canuck motorsport springs on my 03 fire and i love them. They ride nice and firm and provide a nice drop (1.8") They arent expensive either!
I've run the Teins on my car prior to going full coilover. Loved 'em.
