Whiteline 22mm Adjustable Heavy Duty Rear Sway Bar | Multiple Subaru Fitments (BSR49XZ

Like the title states, you can definitely feel the upgrade; better handling=more fun!

after adding this rear swaybar i immediately noticed a difference in stiffness and handling. Amazing suspension mod would definitely recommend. Just took my wrx to the tail of the dragon and the swaybar allowed me to stick better through al the corners.

Installed this a couple weeks ago. Installation would have been easy, but I had a couple seized bolts. Anyway, the difference this made on the vehicle ('15 wrx) is staggering. It would understeer horribly before. I've been autocrossing lately, and it is hard to avoid the car pushing straight forward with the wheels turned. Since I've had this sway bar on, all understeer seems to be gone. If anything, it's a tiny bit tail happy, but I prefer it that way. Have not had the opportunity to take it to the track yet (in a few weeks), but the difference is already very noticeable. Also, the stops and additional bracing that comes with the whiteline helps. There is no squeaking like some have reported with other sway bars. The stops on either side that come with this are important, and as a result, the support bars are needed. Should have been the first thing I got. Factory setup is horrible. This balances the suspension out nicely. Set on middle adjustment hole of 3.

One of the first mods I'd do to any subaru! Super easy install, a lot of bang for your buck.
