CorkSport | Rear Sway Bar Upgrade - Mazda 3 FWD & CX30 FWD 2019+

CorkSport - Rear Sway Bar Upgrade for 2019+ Mazda 3 FWD & CX30 FWD

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.
