I am looking for coil springs for my 98 civic EX, I want an increased rate (stiffer) but stock ride height. I have done a number of searches, even talked to Cory at Eibach, but apparently this is not a common request. Would the springs from a station wagon or a four door from the same model/year be stiffer?

 

Si springs are probably the stiffest stock 6th gen springs I can think of (or possibly a 4 door EX springs) The other thing you could do is use Integra springs.

 

CTR or ITR springs
