Has anyone fitted a thicker OEM rear bar yet from another Subaru?
 
Hi all

I've heard thoughts/comments/statements/myths about other OEM Subaru bars fitting the rear of the GT86/BRZ.

1) Have you done it?

2) What bushes did you use?

:thanks:


edit: Got part numbers for the three OEM rear bars from Subaru:

Others have as well, but he's provided the most information. You'd want to use the bushings from those bars.

Are the WRX/STi rear bars direct drop ins or do you need to find different end links that'll work, and other brackets?

Direct drop in. Rear suspension components for this car were quick to market because they are identical (or at least VERY similar) as 2008-2013 WRX/STI components.

Our end links are the same as theirs. Buy bar, buy correct bushings, fit to car, enjoy.

Just be careful. If you don't upgrade the front bar as well, you are going to make the car very tail happy.

The car's not neutral enough for me, but thanks!

So you're experiencing understeer currently? That would be the only reason to upgrade the rear sway bar without upgrading the front if you're going for "neutral" handling.

ft_sjo 02-05-2013 04:37 PM
That's right.

You are not pushing in this car. If you ARE, you are not driving correctly.

I'd suggest some stickier tires. If traction is your issue, that is your best bet to solve it.

Does anyone happen to have the part number for the 16mm rear bar that'll fit and the associated bushings? Thanks.

Assumming the front is zn6 specific...

We are running a 2011 wrx rear bar on our car with stock front, RCE springs, Koni struts/shocks, and AST camber plates. No issues with the car being too tail happy and that is with -3* of negative camber in the front and -1.8* rear with only .1* total toe in rear.

I'm amazed at how widely varied the opinions on sway bar sizing is with this car.
