Asking to see if anyone knows of a replacement spring that is OE fitment but with a higher spring rate. It's for a 2000 ITR that currently am running bilstien sp's on the stock springs. Would like a slightly higher rate 300-400lb range. But not intrested in most of the aftermarket ones from HR and Eibach and such out there, that usaully slam it, want it to stay around stock ride hieght just with the higher rate. Stock I think is about 264 or is it 246 linear front progressive rear I believe may be of a little. Is there anything out there like this???

 

Actually Ground Control "might" work. Mildly progressive, and spring rates can be customized. I think ITR OEM is 250 F/R. Also, look at HR OE to see what they offer for the ITR.
