7" springs. I'd shoot for a 450-500 front, 300-350 rear. I'd also make some Swank Force Racing approved bump stops.I've got an MSM, I'm going to be on the cheaper end of this spectrum since 99% of my cars use is DD. If I don't want to go crazy and do helper springs, what should I do for spring rates and lengths from summit?
