448lbs in from 671lbs in rear on a 2000 Honda Civic SI with 22mm rear sway bar!

I think the front should be fine, but I think 671lbs might be alot for the rear? What do you guys think???

 

Depends on which shocks you're going to be using.
Stock?

 

i think that we can't tell you what you will like.


it might work for you or it might not, if might work for other's but not for you.


also there are ALOT of other things we would need to know, but regardless we can't say they are good or bad.

the spring rates are up there for daily driven cars but as far as a dedicated track car i think they lack greatly from what most others run, but again it could be g4reat for you or not

 

The difference between a set-up for sometime track use and one optimized for ITS is going to be pretty significant and, as pointed out already, what you can get away with will be dictated by your shocks.

Really stiff springs operate at high frequencies - they bounce up and down over less distance but much faster than softer ones. If shock valving isn't set to deal with this, they won't keep up, will fade, and quit damping spring motion.
