would a 10/9 spring rate with koni spss valved shocks be too rough for a daily driver?

driving on streets and the freeway?

what would be a better spring rate for daily driving and the once in awhile aggressive street driving?

ps. im leaning towards a liitle more performance than comfort.

 

10kg/mm is about 560 lb/in. 9kg/mm is about 504 lb/in.

That shouldn't be too bad if you're going to use the spss3 valving, but it will be very noticeably stiffer than stock. For track days, just swap the springs front to rear to lessen the understeer. Get the same length springs and it should be pretty easy.

 

thanks. i used to track my car at streets of willow. that was pretty fun. thanks tho. right now, i dont' think immma track much. more aggressive street driving. haha
