Spax SSX anyone??

The spax I had on my old car was ok, nothing special though.. I'd go for the H&R springs if you want lower than eibach
 
get some custom springs made. I believe jase had some made to lower the bak of his kw v1s more.
 
i dont know mate. You will have to ask jase. I think a member called ken*** with a red 197 mentioned custom springs on im his project/gallary thread and that was lower than 40mm h&r's. Or do a search on the web.
