Description
Introducing the CorkSport Rear Sway Bar for 2019+ Mazda 3 and CX-30. Improve your handling characteristics, reduce body roll, and reduce understeer by adding a sway bar to the rear of your GEN4. We tested multiple diameters and settled on a 7/8” diameter solid bar to ensure minimal impact on ride quality but with a big bonus to handling.
With fitments for both AWD and FWD setups, you can be sure there is an upgrade that’s perfect for your car. Read on for details and check out the release blog for even more info!

The CorkSport Advantage
Racing Inspired:
With our experience racing our old Mazda 2, we knew right away that we had to figure out a rear sway bar for the GEN4’s torsion beam suspension to help fight understeer. Since there is no OEM sway bar, we had to get creative. The CorkSport GEN4 Mazda 3 sway bar bolts directly to the torsion beam of the vehicle, similar to our Mazda 2 Torsion Bar. Since a torsion beam essentially acts as a sway bar, adding on extra material offers the same effect as moving to a bigger bar with a more typical suspension.
Handling Boost:
The main goal of the CS rear sway bar is to improve handling. By effectively stiffening the torsional rigidity of the rear torsion beam, understeer is reduced, body roll is reduced, and handling feel is improved. We chose a 7/8” diameter solid bar for the right balance of understeer reduction without dangerous oversteer. You can get the car to rotate if you’re really attacking an autocross course but don’t worry, it is perfectly controllable and safe for daily driving and hitting a backroad.
Fitment Focused:
While the concept is similar to our Mazda 2 bar, the design had to be totally unique in order to fit the GEN4 Mazda 3 just like an OEM part. We ended up with a separate design for both the FWD and AWD versions to really optimize fitment. There is one minor drawback for installation though. Some plastic aerodynamics pieces must either be removed or trimmed for fitment. We tried to avoid this; however, it was a necessary evil in order to utilize optimal mounting locations.
Materials & Manufacturing:
Like all CorkSport sway bars the GEN4 Mazda 3 bar is made from 4130 steel for great strength and consistent performance over time. We finish off the bars in CS blue powder coat for FWD vehicles and red powder coat for AWD vehicles. This ensures a great look and corrosion resistance. Each rear sway bar kit also comes with all the hardware needed for installation, all of which is made from stainless steel so it’s sure to stand the test of time. We even use locking nuts so you can be sure your sway bar stays where it’s supposed to.
- Removal or minor trimming of plastic aerodynamic components is required for installation. See installation instructions for details.
- AWD vehicles that are extremely low and/or bagged will need to verify clearance from the top of the sway bar to all other components of the vehicle to ensure safe operation.
- Cannot install on AWD vehicles with a lift kit. The sway bar will interfere with the differential/driveshaft system.

Put this on a turbo premium Cx 30 and am thoroughly impressed . Took it out for a spin and ended up on highway 101 for 5 hours , just couldn’t stop driving . Fit and finish doesn’t get better than this as well .

Put this on my CX-30 a few days ago. I am really pleased with how this has improved the handling of the car. They should have done this from the factory, it reduces body roll and makes the rear feel so much more planted. Less understeer and I cannot feel any degradation in ride quality. Not too bad to install but would definitely recommend jack stands to raise the car up.
Troy Norriss
The Corksport Rear Sway Bar is a definite 'Must Have' chassis upgrade to any serious Mazda 3 aficionado. The driving feel is night and day from the lackadasical stock Mazda offering. You will truly optimize your driving experience after this modification, along with the Lower Tie Bar and Front Strut Tower Bar is complete. For extra curvy canyon carving, tire-squealing excitement and a few sh!ts and giggles, slap some lowering springs on there to boot! Long and short of it, I'm glad I added this piece in sooner rather than later. Worth every penny and the quick hour of time to install

Really good. The car feels more sturdy for sure. (AWD)

Fitment and function…Nailed it! Noticeable difference from stock. Car should have come with this but luckily CorkSport came thru to provide a must have modification. Super easy install that I didn’t realize I needed…until I experienced it!

I have just installed my rear sway bar, and although I have only taken one drive with it, the difference is very noticeable! Even at slow speeds, the vehicle feels so much more planted to the ground! My AWD model felt sloppy in the rear end before installation, and the difference was instant! I would absolutely recommend it to anyone!
Mario González
To be honest I was hesitant to buy this sway bar, nevertheless the improvement is amazing, now my cx30 transmit the confidence to literally take the curve with more speed, 100% recommended.
Corey McCauley
So I will definitely say one of the most easiest installs I've done on this car so far again instructions from these guys is so straightforward and just make things 10x easier. But the handling from oem and the car not having a rear sway bar from stock definitely makes this car come alive and feel more grounded in the corners and not feeling loose. 10/10 would highly recommend.
Rain Cunningham
Truly makes the car feel a world better. One of the best first mods. This car has an complex rear end on the AWD models. The instructions made install a breeze.
Joe Pascuzzi
