Spring rate question.

I have a good ol' set of BBK Progressive rate springs on my 87, and I know the spring rates of the specific set is 650/250 front/rear. Is it safe to say it is similar for the progressive rates? Reason why I am asking is because I will be switching over to a Coil Over setup pretty soon, and want to make sure I don't go too soft, since I already know the suspension will be smoother, but I want to make sure I have something that will make the front end respond similar.


If anyone else is using Coil Over fronts, let me know what rates your using and what brand struts. I was gonna go with a Bilstein/Hypercoil combo, or perhaps the Eibach coils since they have much better reviews. Thanks fellas.

I was thinking between 250-300 for the front. The rear would be done at a later date.

I have a set of QA1 h2003 struts on the shelf, how are they on the street?
