Coilovers or an LSD?

I have a 2009 335i coupe. My mods are: Drop-in Filter, RPI scoops, AR catless downpipes, HPF cat-back, COBB AP on stage 2 mapping.
At this point my traction isn't always there, so I'm leaning towards a Diff. How big of a difference do they make on a stage 2 car? Also which one would u recommend? (Wave trac, Quaife, OS giken?)
I don't plan on tracking the car, but do coilovers make a big difference on the streets and occasional twisties?
Thanks.
