What’s a comfortable drop I can do?

Looking for some advice on what a comfortable but styling drop using lowering springs and new shocks. I’m a newbie, I’ve tried doing some research and just looking for some more opinions. I’ve got 225/40 R18x8.5 +45 offset wheels. I’ve got just over 3” front and 2.5” rear gap on these. I’ve looked at the H&R sport (1.3” drop) and touring (0.9” drop) cup kits along with the Eibach pro lowering springs with bilstein shocks. I daily my car and don’t need super stiff suspension. And yes, I know the wheels are not the perfect size to go low, just looking to see what I can do instead of buying new rims. Also worried about rubbing if I go over an inch drop.

Thanks for the help!
