Well guys I'm not sure bout the USDM or EU ones but for the JDM ones I can tell you the following..

If you have a pre-facelift outlander between 2005-2009 and is a 2.4 then you have a smaller sway bar setup in your car..
However if you have the 3.0 then your sweet and have the larger roll bars.
So if you want to upgrade your 2.4 pfl simply get the 3.0 ones or if your a facelift owner your lucky you already have the updated bars...

Another thing the updated upgrade allows for exhaust system in the bar too

Anyhow thought I'd share this info for the ones that may want to know

 

My 2012 Outlander XLS (GT US version) did not come with the sway bars like it did in the previous years. Did anyone purchase an aftermarket sway bar for their Outie? I thought there was one made by Cusco, but can't seem to locate the website again.

 

Outlander Sport can fit a non-sportback/evo Lance front sway bar, might want to check for the full size Outlander. I bought a regular Lancer sway bar and is was a direct bolt-on, perfect fit.

 

I had an 08 which had a strut tower bar and my 2012 XLS didn't. Apparently the suspension has been beefed up for 2012 rendering the strut bar useless.
