Remove the tendency to overpower the front tires under hard cornering and minimize traction robbing body lean with the CorkSport Mazda 3 Rear Adjustable Sway Bar. Compressing inside suspension, the CorkSport Mazda3 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 Mazda 3 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.
The CorkSport Advantage
Adjustable: Two endlink attachment points to change the swaybar from 130% to 220% stiffer than stock.
Single Piece: A single piece is used to create the rear swaybar which adds strength by removing weak points such as welds.
Billet Swaybar Brackets: Superior bracket design with grease fittings for easy servicing with 90a durometer polyurethane, our brackets and bushings are the last you will need. Once installed, the reduced bar movement gives you extra confidence when taking corners.
The CorkSport Advantage:
Extra Value: Includes Billet Swaybar brackets, at $79.99 value.
One piece design: CNC bent for precise fit and made from 25mm 4130 Steel.
Adjustable: Two adjustable locations for the end links to install allowing you to change how much the bar uses the other side of the suspension. 130%/220% stiffer than stock on the Mazda 3.

This rear end sway bar is not spec'd to OEM size or shape.
If you plan on upgrading any other parts of your suspension setup, like the springs or the end links, this rear end sway bar will cause you some serious headaches.
I don't understand why an aftermarket car company would design and sell a product that requires an OEM suspension setup, but that's what we are being offered.

It's been many months since my install and original review. Now that my stock tires are worn down, I have been throwing the car around quite a bit. Understear has been almost eliminated. There is so little understear, that it could be dicey in the wrong hands. I can cruise thru an empty lot at 35MPH and throw the steering wheel hard over and get the rear to loosen a bit. I suspect new "better than stock" rubber will help. I may need to play with tire pressures too.

Best ever mod for high speed avg 105-115mph twisty roads even on soft setting. Finally got for my setup right with this RSB. Get this if you want to keep up with modded Hondas on twisty roads.

Works very well and a noticeable handling increase can be seen. Well worth it. Highly recommend getting a professional to install as it's a lot of work.

I installed it on the stiffest setting and man oh man it's amazing. I don't rally or anything like that so it was for my daily driver. Helps so much on the freeways and highways, made the car stiffer ride but I don't mind it. I totally recommend it.

Good improvement. Make sure to have a 14mm ratcheting wrench on hand as you will need it quite often. 1 star off for difficulty. Basically impossible to measure torque on some of the nuts.

OK..... Let me start by saying this is a great bar and really makes a difference to the neutrality of the car.
Installation was a rough game on the Mazda 3.
Removing the wheel, the link to the old sway bar and the spring were easy. Removing the bolts for the old brackets was a very hard procedure without half height or pass-thru sockets. Tightening the new aluminum brackets was even harder due to the shape of the milled brackets.
I finally gave up and had to drive the car to my mechanic to tighten the brackets completely.
Be sure to have the right tools for this job. I thought I have a lot of tools, but not the right one for this job.

I have had the CS rear sway installed for a few weeks. The only thing that makes this product fall short is the install in my opinion. Difficult to get the inside bolts on the billet bracket tightened up, the space is ridiculously tight to begin with and the added size of the bracket makes it more difficult. I ended up getting it to a mechanic who used a lift which made it easier to tighten down but even he said it was difficult. Corners like it is on rails though!

Great product, did this with the springs, Install was a little tight, but I have bigger hands lol. If you enjoy driving at all, I'd recommend just going straight to the stiffer setting. If you have 18" wheels, you'll need it. My 2L/6Spd Touring hatch just killed a built R32 GTR in the local autocross; and I gotta say, I'm more than stoked!,Thanks Corksport!!

Just an update as I've driven on the stiffest setting for the past week or so.. it's even more amazing now! Hardly any body roll at all and understeer is at a minimum, slightly stiffer springs (hurry up already! lol) will probably get rid of the rest. It takes corners like a dream, turns that use to squeel tires are solid and all grip now. Definitely didn't need bigger/stiffer bar though, not for street use, this one is perfect! I can't wait to go tear up the Tail of the Dragon next week, I just wish I could have had springs by then.. but stock + this bar will do just fine, it's a great improvement and 100% worth the money.

Just installed it on my Sedan a couple days ago. I immediately threw my car around every corner and the difference is very noticeable. I don't even have it on the stiffest setting and it has reduced the understeer significantly. Install was a lttle tedious and but worth it!
Shane04/01/2014, 12:23 PM
I've had the bar installed on my sedan for about a month now and am enjoying it greatly. The install was a bit involved but the clear and detailed instructions were very helpful. It took a bit over an hour from start to finish but was well worth the time and money spent. I've only used the bar on the softer setting so far and can still feel a difference when cornering hard. The rear of the car stays planted and reduces overall body roll. I think the rear bar will compliment a lower and stiffer suspension greatly, I recommend it to anyone looking to improve cornering feel and overall handling. Well done, CorkSport!
John03/13/2014, 10:22 PM
any idea when the front sway bar will be released
James02/22/2014, 05:11 PM
Are you sure this will work with the sedan as well?
CorkSport Reply:It fits.
Mitch01/30/2014, 11:21 AM
Does this work on both Sedan and Hatch?

The anti-sway bar for the 2014 Mazda 6....
On a hoist, I and a mechanic friend looked under the rear of the Mazda. The small OEM sway bar is attached with two small vertical rods....to a sway bar that is 'buried' above a lot of other metal.
How would the new sway bar be installed?
Does it install in the same location as the OEM sway bar?
Or does it hang under and connect from underneath?
