I'm debating on which brand to get. I'm looking at the Eibach kit and the Addco kit. Any recommendations?

Thanks.

Eibach if you want to retain your understeer.
Front bar larger than the rear


Addco if you want less understeer.
Both bars equal.


Personally I'd go with addco.

Larger in front = Understeer (Stock setup cause there is no rear bar)
Slightly larger (+2-3mm) in front = Mostly neutral setup
Equal front back = slight oversteer (some like this, others do not)
Larger back = Stronger oversteer (most don't like this, few do)

Stock LS is 19mm IIRC.
Stock Z24 is 22mm IIRC.
Addco 1" is 25mm. (Fairly neutral, slight oversteer)
Eibach 26F/22R (makes fairly neutral, some understeer)

The front of the car is heavier (engine) and thus needs a slightly larger bar to keep the car neutral. I personally think an Addco 25 in the front and Eibach 22 rear would be the most neutral. But they don't offer that combo. What you want dictates which kit you should buy.

Thanks guys, I think I'm going to get the Addco. I'd rather have some oversteer.

Wait till you drive with no throtle steer, and an oversteering car in the snow, makes for an interesting ride. That is why I went with the Eibach kit. I also am using the D-specs so that I can also induce some oversteer advantage with those as well, when the weather is nice.

Remember the LS Sport 2003+ has a 24mm front sway bar.

Hmmm

I've got the Mantapart 26mm front and rear, with stock springs/struts. I'd say the ride is pretty neutral most of the time, a bit of oversteer if I really get on it. Meaning I can throw the rear end out if I try, but it doesn't come out on me by accident.
This will probably change after I decide on which strut/spring package I want to go with.

So should I still get an aftermarket front one? or keep the front one that comes and just get a rear?

Aaron52788, It's your decision. I Think a 24mm bar is enough but you have to decide how stiff you want to go. A 26mm bar will give you more stiffness and depends on your driving needs to keep the factory or upgrade to the next step. Remember, try not going thicker on the rear than in the front. Good luck.
