I have Qa1 R shocks on the front with springs. It seems they may have quit making the qa1 oed 315 s spring because I can't seem to find it anywhere. I need specs so I can order a new spring rate.

I'm thinking maybe a 175-200 spring. The car is very light on the front (only frame rails and bars running from cage attached to strut towers) The front is so stiff right now that it barely goes down when I stand on the front.

 

Found info from QA1. They recommended 15HTFB275
specs are 2.5" 15"
I will probably go with a lower rate than 275
