MS6/MZ6 Rear Camber Arms

CorkSport is pleased to reintroduce the the 1st Gen Mazda 6 and Mazdaspeed 6 Adjustable Rear Camber Arms to complement the return of the CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6!

By replacing the stock camber arms with the CorkSport Adjustable Camber Arms, you can adjust your suspension to accommodate for lowering springs or coilovers and fine tune your Mazda 6 or Mazdaspeed 6 to the appropriate camber setting needed to balance uneven tire wear and improve cornering performance.

Mazda 6 and Mazdaspeed 6 Adjustable Rear Camber Arms

Our design offers +OEM to – 4.5 degrees of adjustability along with cross camber adjustment allowing drivers the ability to align their suspension to match their enthusiastic driving style on and off the track.

Unlike other adjustable camber arm options on the market, our unique design includes spherical bearings that replace the soft rubber bushings on the OEM camber arms, providing a true attachment to the suspension of the vehicle for improved handling and road feel.

MS6/MZ6 Front Camber Arms

We are happy to announce the return of the CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 and GEN1 Mazda 6 to complement the return of the CorkSport Adjustable Rear Camber Arms. Back and better than ever, the CS control arms provide improved handling and easier wheel fitment through front camber adjustability. An impressive 4.5 degree adjustment range ensures you are able to get the camber you want. Whether you are dialing in your handling for the track, correcting your added camber from lowering, or even just adding in more camber for that new wheel and tire setup, the CS adjustable control arms are a good fit for your build.

CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 and Mazda 6

The focus of the CorkSport Adjustable Control Arms is an easy modification of the OEM camber setting. You only need to jack up your car to easily access the four bolts on top of the control arm. Once loosened you can adjust as needed before tightening everything back up and lowering your car, without even removing a wheel! It’s a great setup for correcting camber from pothole damage or lowering, optimizing your alignment for the track, or adding negative camber to get the stance you want to fit that new wide wheel setup.

Modify your Camber setting without needing to remove your wheel!

At CorkSport lowering spring height (1.5” lower than OEM), our local race alignment shop measured an adjustment range of approximately +0.5° to -4.0°. During the measurements they even complimented how easy the CS arms are to adjust! If you’re lower than CS spring height, you are able to go even more negative due to the natural camber gain of the MS6 double wishbone front suspension. While if you are higher than CS springs, you won’t be able to go as negative.

Truly an easy bolt-in installation with no strange handling geometry changes

Because the CorkSport upper control arms replace the entire OEM upper control arms, we knew that fitment was vital to ensure correct handling characteristics, and an easy installation. These arms were designed directly from the OEM control arms so they are truly an easy bolt-in installation with no strange handling geometry changes. With the added camber adjustment, we also verified clearance throughout the suspension travel and at all camber settings to prevent any strange noises or damage to your vehicle.

Long lasting strength for your Mazdaspeed6

We have put the CS adjustable front camber arms through extensive real-world testing to ensure long lasting strength for your car. We have been testing an early production unit on a MS6 for around 6 months at the time of writing. This car has been used in everything from daily driving, to aggressive driving in the twisties, to even hauling heavy loads around. Throughout all of this, the car has been setup with -3° of camber with a 255/40-18 summer tire on a 9.5” wide wheel.  We have seen consistent performance out of the CS control arms with no issues whatsoever, so you can be sure they can take whatever you can throw at them!

CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 and Mazda 6

Each set of CorkSport Adjustable Control Arms is made from A513 steel for long lasting strength and durability. The camber adjustment box on the arms are gusseted for added strength and rigidity. The arms are then finished off with a black powdercoated finish for long lasting corrosion protection and a great look. Each kit also comes with brand new ball joints, castle nuts, and cotter pins to keep everything operating correctly. Plus, we upgraded the rubber bushings where the arms mount to the chassis to spherical bearings. This change ensures good consistent handling feel and reduces slop that can result from old worn out rubber.

Mazda 6 Turbo Lowering Springs Release!

2018+ Mazda 6 Lowering Springs

We at CorkSport are happy to introduce the Sport Lowering Springs for 2018+ Mazda 6 equipped with the 2.5L turbocharged engine. In our last post, we talked about the height, handling, and quality of our new springs. If you haven’t seen it, check it out HERE. Today we’ll cover how we tested the ride quality and go a step further to talk about damping and natural frequency. I’m going to warn you now; this gets a little bit complicated, but we’re happy to answer any questions you may have.

Spring Damping

Let’s start with a basic example–your car hits a bump which compresses the spring. It “springs” back to its normal length. In a perfect world with no friction or damping, the springs in your suspension would keep bouncing up and down forever, this is called oscillation. Add back in dampening and friction, and the spring will settle out to its normal length pretty quickly. How different strengths of damping affect the “oscillation” can be seen in the graph below.

Spring damping graph
Spring damping example.

The car has hit the bump at the bottom left of the graph. As time goes by, you can see the spring expand and compress and so on. The Greek letter is not important but what is important is the numbers. When it is 0 (black line) the spring compresses and expands over and over to the same height. As the number increases, you can see that the spring returns to its normal length faster until it gets too large and overpowers the spring (dark blue line). For a car, the 0.4 to 1 range is ideal as there is minimal “bouncing” without having too high of damping.

What does all this mean though? Let’s say from the factory the car is in the 0.7 range (orange line). If we went to a drastically stiffer spring, but kept the OEM dampers, we may end up in the 0.2 range (light blue line), which would be uncomfortable due to all the bouncing every time you hit a bump. The CorkSport front and rear spring rates chosen are small enough of a change to fit well with the OEM damping, ensuring no bouncing.

Natural Frequency Analysis

To go along with this, we did some natural frequency analysis. Natural frequency simplified is how quickly the suspension responds to a bump. Higher the natural frequency, the harsher the ride in a car is. Most “regular” production cars sit in a 1.0-1.6 Hertz (Hz) range for a comfortable ride. Sports cars are usually in the 1.6-2.3Hz range. Full race cars are usually 2.3-3.0 or even higher. An average person will start thinking a ride is stiff/harsh at around 2.0-2.2Hz. Using a special app that ties into the accelerometers of a cell phone we can approximately measure the frequency of a specific suspension setup. With stock suspension on the Mazda 6 2.5T, this yielded ~1.4Hz front and ~1.7Hz rear.

With a stiffer spring, these frequencies will increase, but we wanted to be sure to only increase them slightly, to not severely affect comfort. We went through a few different combinations to get our ideal result. Our final setup ended up at ~1.5Hz front and ~1.85Hz rear. This is enough to notice the suspension feels “sportier” without riding harsh.

2018+ Mazda 6 Roller Shot

There is one other big thing to highlight with frequency. Notice that both the OEM and CorkSport springs have a higher rear natural frequency than front. If your natural frequency front to back is close to equal, the car has a tendency to “pitch” front to back over bumps. Since your rear tires hit the bump slightly later than the fronts, to have a comfortable ride the rear suspension has to “catch up” to the fronts to prevent this pitching back and forth. If a frequency is too much higher in the rear, it can be too fast for the fronts and cause the same pitching issue.

Natural frequency was always on our minds when designing the CS springs and we tested a bunch of different combinations to determine the optimum balance of ride and handling.


That about does it for the Mazda 6 2.5T Sport Lowering Springs. Be sure to let us know if you have any questions-suspension is hard, even for us! Lastly, be sure to share your MZ6T with us by using #CorkSport.
