if you already have the shocks call up ground control or any major spring company and you should be order any custom rate you want.

and why can't you lower the car? something about your frame? can you elaborate....just curious

 

Are you running with SCCA or another club? If it's SCCA what class are you looking to run in? If it's another club, what are the suspension rules?

 

Bent the front right wheel well area moving the tire 3/16" offset and if its lowered the tires will sit almost sideways. I found a repair shop that said they can fix it for 260 so I'll probably do that and I'm running in ST.
