Right, but not only wings affect overall downforce level. Lowering the ride height produces extra aero grip, and the less downforce you have the more comfortable you'll need to be with your ballast, springs and anti-roll bar settings, since more mechanical grip is required to cope with shifts in the car's balance under braking, turning and accelerating. It's no use having 1/1 wings for least drag if you're unloading and locking the front tyres all the time.
