Thanks!

I ended up calling H&R to figure out the spring rates and they told me they don't divulge that information and also pointed out that since they're progressive, they're "not sure". Riiight. Either way, ended up ordering the ST XA coilover setup this morning. Very excited to get those bad boys in place!
