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 sway bar is fantastic. The car feels so much more balanced than it was and you can really get some speed around corners. I've only done the soft setting and I think people who have done the stiff setting may be a little crazy haha I think that would definitely shift the balance to oversteer which I'm not looking to have in a street car. Install was trying but that's more an issue with Mazda's design than anything. Deep sockets were crucial to getting the bolts on the brackets installed. I also had to take the endlinks off completely to get them off the swaybar. I probably did something wrong, but I didn't have enough clearance to just disconnect the endlinks from the sway bar. I may switch the bar to stiff after I get a front sway bar, but although I haven't tried it, I probably wouldn't recommend stiff with nothing else done. Well worth the money in opening up the car's handling, especially if you've gotten summer tires.
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!!
