There are a few options out there for adjustable coilovers along with KW and Bilstein.
K-sport /
D2-racing 36 step adjustment, appear to be good value.
Intrax
HDA 40 level adjustment, very good they are too.
Cobra
Evo III not much info other than they are adjustable.
Last but not least, Tein
Euro Damper 16 step adjustable, the thing that set these apart are that they can be combined with
EDFC allowing you to change ride firmness on the fly.
