2004-2013 Mazda 3 Rear Adjustable Sway Bar

Very nice rear bar with easy and comprehensive instructions to boot. Created a night and day difference in handling with my 2008 Mazda 3s and can't go back to any other cars after installing. Careful under highspeed trailbraking cause your back end will want to step out.

After multiple suspension changes on my '12 Skyactiv hatch, I settled on this bar on the firmer setting and Bilstein B6 shocks with stock springs. The bar alone makes a dramatic difference in handling, significantly reducing body roll while still taking two wheel bumps like speed bumps etc well. You will definitely feel single wheel bumps more, but the confidence and balance are well worth it if you are at all "enthusiast" inclined.

Caution! Be very careful with the soft, weak threads that you'll be bolting into the subframe. It's not uncommon to strip the threads, as I did on one of the 4 mounting points. A torque wrench is a must.

I experienced a noticeable change in handling but nothing dramatic. I also paired this swaybar with whiteline adjustable endlinks since the stock endlinks looked like they needed to go.



This might be common sense but since it is quite stiffer, it will magnify any weak points in your rear suspension that you might already have just couldnt notice. In my experience, my rear shock mounts are rusted and rattle more with the swaybar on than before. Hopefully I can get rid of that rattle when I have enough for the corksport coilovers.

All I can say is if you want to improve handling, if you want to improved control this is what you need. You will immediately notice the change as soon as you start driving it is worth every penny and that's why I'm buying the front Swaybar ASAP. Get it you won't regret it.

From the factory, my '12 Skyactiv 3 hatch had an annoying amount of understeer, so I bought this bar to replace it. Installation was easy and trouble free except that a bolt stripped the threads at the spec'd lb'ft with a torque wrench. Replaced with same size bolt and nut, set the bar to the stiffer setting, and done.



The difference is immediately noticeable. Turn-in is more immediate and controlled, cornering speed increases, and the car now feels just much more balanced. Driving a gravel road at speed is great fun. You can easily throw the back end out with some sharp steering inputs, but it's very controllable and never scary. When driving at high speeds in the wet (track) the slip is almost even, making the car almost feel like it's just moving sideways a little, with neither front not back out of balance.



One major flaw is noise. This thing is noisy no matter what I do. I've taken the bar off to regrease 4 times now in under two years. One very helpful fix is USE TEFLON TAPE around the bar where it meets the bushings. Along with a generous amount of silicone grease (I used SuperLube Silicone) this bought me around six months before it started squeaking again. If you don't use the tape, I get maybe a month before it's squeaking away again. It's annoying and embarassing, and the bar will have to come off when the car is sold so people don't think the car has problems.



For an enthusiast, this bar is great. It gives more control, more confidence, and more fun. Worth every penny. For an average joe who just wants to put parts on their car, be aware that this bar will require repeated maintenance to keep you sane. You've been warned.
