How to Install the Tanabe Rear Sway Bar on Subaru BRZ

Difficulty: Very easy

Built for the driving enthusiast, the Sustec Stabilizer eliminates roll for exceptional stability and maximum tire contact patch and grip.

Unique to the Sustec Stabilizer is it's FULL CHROMEMOLY steel alloy construction. Chromemoly's strength is such that a small diameter chromemoly anti-sway bar is significantly stronger than the standard steel anti-sway bars that are larger in diameter.

Chromemoly anti-sway bars, which have typically only been readily available to race users, are now available to all motorsport enthusiasts.

In this write up we will show you how to install the Subaru BRZ Rear version of the sway bar.

Step 1

To begin this project you must either get the car up with an available lift or use jack stands in order to elevate the car where you need it.

After this is done, we can begin the removal. With a 14mm wrench, loosen the nut supporting the end links to the rear sway bar.

Step 2

Now using a 12mm socket and ratchet, remove the two bolts securing the bar to the chassis. These bolts also hold on to the brackets which will come off as soon as you remove the bolts

The top sway bar bracket bolt may require an extension due to its position. Maneuver around the exhaust if necessary.

Step 3

Once these bolts and brackets are removed, you can now remove the rear sway bar.

Carefully slide it towards the passenger side of the car and be careful not to damage things on the way out.

Step 4

Once the OEM Rear Sway Bar is out you will have completed your de-installation of the unit.

Here just to gather we weighed the unit for our own archival purposes. The Stock Rear Sway Bar weighed 3.70 lbs.

Step 5

Our first step of the Tanabe sway bar install is to maneuver the bar around the exhaust and attach the end links.

Secure but do not tighten the Tanabe sway bar to the end links. This will help keep the bar in place while you go prep the bushings.

Unlike the front Tanabe Sway Bar install, with the rear bar we can secure the bar first and then follow up by lubing the sway bar bushings.

Step 6

Be sure to use the appropriate lubricant. Like our Tanabe Bar, many sway bars come with the lubricant already in the box.

After lubricating the bushings, place them on the Tanabe Rear Sway bar.

Insert them through the opening and go ahead and acquire the metal brackets next.

Step 7

Install the sway bar support brackets with the hooks facing upward. They need to grab a hold of the small opening in the rear sub-frame.

Begin by threading in the lower bolt to the sway bar bracket so that the hold mechanism is held tight.

Then proceed to install the upper bolt.

Step 8

Once you are sure that all bolts are correctly threaded, you may now secure the bracket to chassis.

Step 9

Complete your install by tightening the end links at both ends of the bar.

Step 10

This rear sway bar is definitely a noticeable upgrade despite the weight. Better car rotation and control is how it should be from now on.
