This adjustable "locost" tool can be used to figure out where the mounts need to be in order to align with a specific model coilover. Actual mounts should be made using the actual coilover.
With the negative camber set to the most you might ever use (1.5deg?), start with 3 inch droop and the fully extended spec of the desired coilover to position the temp mounts as far outboard as will clear the UCA and trying to ensure the LCA doesn't bend from hitting a pot hole, then raise the suspension to 3 inches of bump and measure the eye to eye distance of the temp mounts (or adjust the tool to fit and measure that) to determine if the desired coilover is going to work.
Damping rates are a separate topic. This is just about fitment, to be followed by spring rate selection.
