Sway Bar Brace, Worth it?

Look at how flimsy those mounts are. Can't actually be doing anything.

I think it looks cool OP, but like everyone is saying I don’t think it will do anything.

A friend of mine installed these on his 2011 STi with his bigger rear sway bar and I thought it was pretty cool/maybe needed back then. Fast forward nine years and I haven’t heard of the Subaru sway brackets snapping, especially on the brz.

But if you like them, I say get them. They are cheap enough and if you ever get bored you can duck underneath the car, look at the braces, and go woah that’s not stock.

It’s only money. People have spent more for less.

My theory is products like this get carried over from one chassis to another through the manufactures desire to sell anything and the consumers knowledge of another chassis. For example. A previous owner of an E36 would think that a sway bar brace is needed on a twin because the E36 rear sway bar mount are prone to bending/tearing.

Also, manufacturers will look at a product that sold well on one chassis, and make it for another not because it solves a problem, but because it sells.

I believe strut tower bars also fall into this territory. A completely useless item on one chassis (the twins already have a triangulated brace to the firewall), helpful one an another (like the disturbingly weak strut towers on an E36).

I wonder which car started seat rail braces?

Even Grimmspeeds own data only shows about 5/32 reduction in deflection across the front end though I would be curious what the reduction is cross-corner. I have driven a stock FRS with one compared to my BRZ when it was mostly stock and couldn't tell much of a difference.

Even then, I bet you felt the difference in the spring rates, not the strut bar.
