I've been looking to get rid of the body roll my car has, but not promote too much under steer, and I've heard an open diff with a stiff rear bar can be bad news. So that said, what's the best front bar to get, to help tame body roll, and not promote too much understeer in harder tighter corners? Or is it really not that bad wih both bars (like eibachs kit). I'm on eibach springs and B4 dampers stock otherwise. Springs helped a bit and so did dampers and rear subframe
Inserts but it still leans more than I'd like and the weight transfers can be unnerving at higher speeds of off camber corners

I went front bar only but ended up also mating with the rear for more balance as the rear felt disconnected. Therefore, I highly recommend you replace both bars or you may end up going with the rear eventually if you want to try front only.

Popular brands are UUC, H&R, whiteline, Eibach to name a few. Let me know if I can help with anything else.

eibach has the largest diameter solid sway, i believe

The Whiteline solid 27mm front sway bar is pretty cheap:

I've read that you shouldn't upgrade the rear sway bar unless you have a LSD.

The e-diff stuff is nonsense. It all depends on your tires. The car should take nicely to M3 bars front and rear on 300tw street tires like mpss. Go stickier like 200tw tires and you'll probably need aftermarket bars front and rear. Move to r-comps and youll need aftermarket bars and some stiffer springs.
