What number was on your springs? I got a set of yellow neuspeeds that say 5504F and R, but I can't find any matching neuspeed part number, the closest is 552004 88-91 CRX/Civic. Any help would be appreciated.

 

I know this is a long time since the last post, but I have searched for days for a answer.

I also have yellow springs, labeled 5504F (on the front springs. I haven't checked the rear yet).
I'm looking for any info on these springs. They are mounted with "Koni" shock front and rear, on a 89 CRX.

Thanks

 

whoa.. thread bump from '06.. i would guess they are 550 in/lb springs.. 550 in/lb is a fairly common rate to run on the front of the EF. I would guess that any spring of similar dimension, likely 7 inch tall, 2.5 inch center diameter spring would probably fit.. Just measure the front and back springs and go to eibach's site and they can set you up with exact matches for about $50 a spring.
