2004-2013 Mazda 3 Rear Adjustable Sway Bar

Comment

Let’s be honest… You’re not looking at this bar because the rear suspension feels a little sloppy when all your kids are packed into the back seat. You’re not considering this because body roll makes transporting your late great-grandmother’s fragile heirloom china a bit too sketchy. In fact, I’m not even convinced you came here looking for this bar.

But I think you’re searching for something. Hunting for it. Starving for it.

You’re after that incredible feeling of being glued to the road as you rip your family muscle wagon through a banked 180-degree interchange ramp—while your wife screams at you to slow down. The zen it brings on a late-night run through the mountains, weaving through corners with snappy precision. The satisfaction of shaving down your lap times. The smile you can’t wipe off your face after nailing a clean autocross run.

But here we are—you, looking at this bar, and me, here to tell you it can do every bit of that. Bottom line? It’s worth it.

There are plenty of great modifications you can make to a Mazda 3 platform, but upgrading the rear sway bar is a must-have that instantly transforms how your car feels and drives. This bar is beefy, well-made, and comes with two settings, allowing you to fine-tune your suspension to match your other upgrades. Plus, it includes upgraded billet mounts that are greasable—a solid bonus for durability and ease of maintenance.

If I had to recommend just one performance upgrade to anyone new to the platform, it would be the CorkSport rear sway bar—hands down. The only regret you’ll have is not installing it sooner.

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.

Just installed this kit today on my Mazda 3. Bar and brackets seem well made and strong, bushings feel like quality material. Wish the bracket bolts were included as well as they seem to rust easily but they were 20 bucks at the dealership. Bar works with Moog end links can confirm.

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.

A great bar that included some of the nicest brackets I have seen, which makes this a great value. THEY JUST FORGET TO MENTION THAT THIS BAR IS DRILLED FOR THE LARGER MAZDASPEED END LINKS. You might as well replace the links anyway, so make sure you buy the right ones. Thankfully I called Corksport and an actual employee with actual knowledge answered the phone, they overnighted the right links to me just in time for my track event!

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.

I installed his product about 2 weeks ago combined with the Corksport front sway bar and I must say the suspension feels so much grounded and the amount of road feel is amazing. Best part is that this stiffened my coilover suspension so everything feels tight and I've gone auto X with this product and it truly makes a difference in your steering! Must have

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.

I have had this in for around eight months and it has been decent. It was a bit harsh over bumps and it wore out my stock endlinks, something I knew was a Mazda weak point. This product is well made and easy to install, but it came I've once I got the mid chassis brace a few weeks ago. I guess this bar was so sturdy, that it brought out the weak point between it and the front, causing more flex than the factory brace could handle. Now my car seems to only be limited by the factory tires and springs.

This took a little while to install because of Mazda's endlink design, I replaced them with Moog heavier duty ones, but only because Corksports were out of stock at that time. With the quality of the mid chassis and this rear swaybar, I think I'll be picking up a few more pieces that make my car a go cart.

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.
