Remove the tendency to overpower the front tires under hard cornering and minimize traction robbing body lean with the CorkSport Mazdaspeed 3 Rear Adjustable Sway Bar. Compressing inside suspension, the CorkSport Mazdaspeed 3 Rear Sway Bar effectively increases the spring rate on side of the suspension which is compressed most and its adjustability allows you to fine tune the handling. Each Mazdaspeed3 swaybar includes machined 6061-T6 aluminum swaybar brackets which are more durable than the stamped steel design common with other swaybars and look sharp with an anodized black finish.

    How to install a Mazdaspeed 3 rear swaybar

Corksport was very helpful. I ordered this and informed them that I would be moving out of state and they were helpful enough to get this shipped to me and keep me updated the entire time through the receiving of the parts and shipping the sway bar link itself. The sway bar itself is great quality and sturdy enough to hold up. A great replacement for the rusted bushings and sway bar that's on my car currently.
So much better than stock happy I waited for it. Definitely worth the upgrade.
I've had this sway bar on the stiffest setting for only 50 miles and I am impressed. Installed with a new pair of end links. The car is much more confident in cornering and this has got to be my second favorite(after rear motor mount Stage 11) and instantly noticeable install.
I bought this RSB for my 08 speed3 over a year ago. Install was a little longer because I had to cut the old sway links off but it wasn’t bad. I went straight to the stiffest setting and haven’t looked back! High speed cornering has vastly improved. The car feels like it’s on rails. This RSB coming with the CNC mounts makes it a no brainer over other options available out there.
I've been driving with this for about 2 weeks now on the "low" setting I guess you could call it, and this has definitely corrected the issue with understeer. I'm actually curious about trying the "high" setting just to see how it feels. As always CS provided absolutely beautiful craftsmanship. I mean the brackets alone are a true work of art.
drive with confidence. I wanted this for a while and betrayed CS for a different brand and it didn't work out too well and I suffered greatly. I have over 10 CS products so far and they haven't get me down.
In December of 2016, I installed the rear sway bar on my 2011 MS3, which had an otherwise stock suspension. Installation straight-forward and can be done in under an hour, including time to lift the car and setup. Some of the bracket and end link wrenching angles are slightly awkward, and I found a 0.5-in drive to be helpful on the bracket bolts. I used the stiffest of the two end-link positions.

Driving impressions...I appreciated the “tucked” in feeling of the rear end during cornering and decreased body roll, which made canyon carving more comfortable. In my experience with aggressive street (not track) driving, the RSB on its stiffest setting does not turn the car into an unpredictable drop-throttle oversteer monster, even in lower traction conditions. Breakaway is gradual and predictable. My suspicion is that the large degree of static camber and camber gain in the rear suspension help with cornering traction.

In all, I am very pleased with this RSB kit. The fitment is excellent and the spring rate is perfect. The brackets are impressively high-quality pieces, and I have had no squeaking issues to date. The RSB works best with a stiffer FSB - see my review there for more details....
WOW, perfect for cutting out much of the understeer and flattening out the handling. Awesome!
For me this upgrade is by far the most noticeable and easiest change to my Mazdaspeed 3. I thought the OEM rear sway bar was impressive but the Corksport RSB puts the OEM to shame. So much fun now taking corners. I can't wait to upgrade the front.
Put this RSB on this weekend. Easy to install. The only PIA part was getting the top bolt on the driver side bracket to go in. This just due room(part of the heat shield is there, along with man hands). Also did not have to take end-links completely off, just unscrewed top nut to the top. Noticeable difference of body roll or lack of roll during spirited cornering. One-piece design. I highly recommend.
