a coilover isnt going to fix that rubbing necessarily. camber plates and/or rear lower control arms and a proper alignment is what you need. possibly a fender roll.
that said, the Cygnus x1 is one of the best entry level offerings i have ever seen. Geoff Cygnus will work with you and your goals to have the perfect setup, valved for the spring rates you want, so it can be geared towards motorsports or comfort for a daily. they are made by fortune auto and serviceable/upgradable in virginia. have a 5 year warranty on them. and with the custom valving they offer quite a bit that other entry level offerings do not. I got mine with caster/camber plates which you'll likely want/need here.
