you should be able to using the no spring compressor method, but you will definitely need to loosen the lower control arms in order to get enough articulation to drop the coil overs straight down, pull the top hats and reinstall with longer bots and spacers.
btw, be aware that urethane spacers can warp/ compress over time. pretty sure thats what this kit is packing. better to get 2 inch longer coils. really like the icon's on my set up.
