I saw a pic with one under the car and I also saw one in the trunk. the one in the trunk went across like the front strut bar.
are they just to different kinds are what well I would like to see a pic of someones

 

The RSB (rear sway bar) is the one that runs behind the rear axle underneath the car. The RSTB (rear strut tower brace) is the one that goes in the trunk. The RSB is supposed to be more effective, however the combination should be the best of all. Just trying to help .

 

Actually I have both and didn't notice much difference with the RSTB. I would say get the FSTB, RSB, but skip the RSTB.

 

it does the same thing as the front strut tower brace. it connects to the shock bolts. what it does is box your suspension to keep your tires on the ground when turning. it gives you a bigger contact patch.

 

In the rear silly... hehe i had to do that... since the question was already answered

 

Isn't that exactly what the axle beam is doing?
