Installing suspension, anything we should know?

This sunday i am installing some H&R springs, Tokico Illumina shocks and MM Caster Camber plates on my 94 GT. My friends and i have installed suspensions before, but not on a Mustang. The springs and shocks are pretty straightforward but is there anything we should know about the CC plates that could slow us down? Any tips to make this whole thing a bit easier would be appreciated. We are planning on getting this all done in one day in my buddies fully equipped garage any reason it couldn't be done in a day?

thanks. The drop is 1.75in. They are H&R SS springs. Yeah i already have subframes. Anybody who runs these springs, did you have to mess with the exhaust?
