I don't want to go quite that far -- but I can't drive with the 500/650 I have in there now.

I measured the fronts at about 220 lb/in before I pulled them off the car, Resulting front wheel rate is about 180 lb/in. I didn't measure the stock rear, but would guess they are around 300 lb/in spring. They are progressively wound, so not linear though.
I am running 400 lb/in front / 500 lb/in rear now which works well on smooth race tracks (Barber & Road Atlanta) as well as relatively rough auto-x parking lot course. Good luck.
