      Spring rate help for bilstein coilovers

      I am planning on installing the chicane lm from ATS with bilstein coilovers. I need to know the proper spring rates to work with GW cat 5's out back. I have a 383 sbc with al. heads and intake as well as an aluminum radiator. It is a DD street car but I regularly autocross. Will 475 work or should I still go with the 550?
