Steel bumper and spring rates

I purchased a set of Radflo coilovers for my 2014 P4X a few months ago but haven't installed them yet. At the time I wasn't planning on getting an aftermarket bumper so I went with the 600lb springs. Now I want to get a steel front bumper and most likely a winch down the road. The Shrock bumper and radiator skid plate weighs around 155lbs.
