--------------------------------------------------------------------------------

I have a 90 si shell that I'm building using parts from an 88 dx. I've already removed the sound deadening but some dynamatt style stuff will replace it and I'm using the 88 doors. So the car should be about the same weight as a stock si with more of the wieght over the front end due to the B16.
I drive the car daily so I don't want springs that are too stiff. I've driven in a crx with Eibach Sportlines and I felt they were very comfortable.
Would 325f and 375r be good? Or should I go heavier or lighter?

BTW I also have eibach sway bars if that makes a difference.

 

For over half a year our ‘88 crx si was being driven daily on the street and raced on the weekends. It was a street legal racecar and had 350lbs front 400 rear eibach ers springs using off the shelf Tokicos shocks and an adj. suspension technique rear sway bar. The balance was very good, but compared to other track only cars it had a little too much body roll. Still an ok setup for the track. On the street it was very nice (read: stiff). Compared to other street cars it had 0 body roll, but the ride never seemed too harsh. Definitely a decent street setup as well and made it a good street/track compromise. Good luck.
