So tax return came in and that means Ive got a bit of spending cash to start playing with my baby. I have a laundry list of upgrades but I feel like the most lacking part of the 2013 hatch is the amount of body roll in the rear.
Issue : When cornering the back end seems to bounce a bit and on quick switch backs the suspension does not control nearly well enough to inspire confidence on the road.
Hypothesis : I have been talking to my local tuner for weeks about the best resolution for my body roll issues and he recommended Whiteline anti-sway bars. Adjustable in the front and rear 22mm matching. Matching sizes and mis-matching adjustment points, soft on the front and middle on the rear to help resolve some of the understeer that was leftover from the factory. He also recommended Kartboy endlinks to help tighten everything up.
Fit/Finish : The parts arrived from amazon very nicely wrapped in bubble wrap and super heavy cardboard boxes. they included the locks and the new FADE-TO-BLACK bushings, while everything was well packed i did find that the paint job on one of the braces was a little less than stellar, the clear-coat looked/felt great but the under color was a bit uneven looking. The Kartboys parts looked great and fit like a glove.
Install : I ordered the parts earlier this week and had my tuner handle the install. In this case i am glad to pay my tuner to take care of the swaybars. The cost was fair and I didn’t have to deal with stuck end link bolts under the car while it was on ramps. The install process Is not difficult, as long as you have a lift available and a good set of hand tools ( and a pneumatic wrench ) its about a 2 hour job start to finish. During the installation the technician also switched the struts to prevent the springs from nudging the new thicker end links. The install is pretty straight forward with the provided picture instructions, The install for the endlinks was just as simple but it did require the use of the kartboys spacer set. This allows the endlinks to site vertically to avoid undue stress on the bolts that connect them. The install is even easier if you have your tuner install them for you : )
Driving : As soon as my tuner was complete i took it out to my favorite canyon road, The difference between the factory 13mm rear and the now braced, spaced, and upgraded 22mm Whiteline swaybar is like night and day. The handling is tremendously more responsive and i feel like i can hold a much more aggressive line without the body roll and understeer robbing me of my control. At the top of my drive i pulled over and gave her a push sideways at the bike rack and she moved very little. this additional stiffness is how the Subaru should have setup the suspension.
Recap: I picked up Whitelines 22mm front and rear adjustable sways with kartboys endlinks and spacers. the install isnt difficult with the right tools (very easy if you pay someone to take care of it) and the results are like night and day, i would recommend that everyone upgrade the factory anti-sway bars and I would definitely recommend it as a first mod to anyone looking for a better overall ride.
TLDR : Whiteline anti-sway bars are an awesome investment. : )
