Before I begin, let me say that yes I have searched the forums and done a lot of research on this. I'm choosing between two sway bars, and would like to know which is the best route to take. A little about me and my car: It is 2012 WRX Sedan and a daily driver that will never see track use. All I am looking to do is eliminate some of the body roll and tighten things up a bit. I will be keeping my OEM front sway bar, and both the front and rear end links. This is both because I'm a college kid on a tight budget, and because for my needs I dont think I need any more than the rear sway bar. The first option I am looking into is the OEM STi rear sway. It is 19mm and would allow me to maintain a front sway bias. My concern is that it wont make a noticeable difference in daily driving. The second option I am looking at is the Epic Engineering 22mm rear sway bar. I am looking at this bar for a few reasons. First, it is one of the few aftermarket bars designed to be used with the OEM front sway bar, and safe for use with the stock endlinks. Secondly, it's fairly cheap. Finally, all the reviews I have found for it seem to be stellar. Having the 21mm stock bar in the front with the 22mm bar in the back should make my car fairly balanced, with just a very slight tendency towards oversteer. I think this is the set up I want to go with, but would like a few other opinions. Anyone care to chime in?
