you should get your camber and alignment checked even if you just change springs with no drop to be safe so with coilovers you should get them done within 150-200 miles id say.
when i had my apex fitted they were way out and thats only a 30mm drop. now i have the H&Rs and had them checked soon after fitting them. by the looks of it you can go lower, mine looks lower at the front and the majority of arch rubbing has gone, probably because its been scrubbed away lol.
the main rubbing point is the curved lining that goes over the bumper mounting which i recommend you either cut off/back or bend it upwards, you dont want to do what i did
