coils or mix and match

[330i'02]

i'm very confused right now, i can't decide between coils or just mix and match springs and shocks. I want better handling compared to sport suspension. I don't think i'm gonna track my car but i do drive it up windy mountain roads. I'm leaning toward hr coils but can't decide. thanks

Coilovers are a much better idea for overall performance. Since you won't be professionally tracking the car, it is better to stick with matched coils and shocks.
