I'm am about to purchase some coil-over's in pretty much any spring rate I want. I was just wondering if anyone has some spring rates that they really like for autocrossing and/or road racing. I have progressive rate springs now that work alright, but I am looking for a linear fixed rated spring for more consistent handling. I have an EG civic that will have a B-series in it soon. I have heard that some people running 450F/600R all the way up to 550F/1000R. Any comments/suggestions would be helpful, thanks.
