On page 121 of the March MM&FF, under the JMS ad, they show a new 2005 Mustang 4 point strut brace for $179. Here is all the info they give:

-JMS exclusive 4-point strut tower brace.
-Eliminates suspension & chassis flex on cornering.
-High gloss black powder coated finish.
-Adjustable end points for guaranteed fit & easy install.
-Mounting hardware & insall instructions included.

I tried searching their website for it, but they don't have it on there. The pic in the ad shows a single bar going from strut to strut with two mounting points on each end. Then near each end of the brace, it has a bar going at an inward angle to the firewall.

Here's my lame attempt at trying to show what it looks like:
[attachmentid=43963]

I'm still trying to figure out which brace I want to get and this one doesn't seem too bad.

 

From what I've read, the firewall in the 2005 is not a structural member. So tying a strut tower brace to it would yield no benefit. It could make your engine bay look better, however.

 

Just go with the BMR Strut tower brace. It bends back toward the firewall but doesnt attach and it looks really cool.

 

I had been looking for one of this type too, but after seeing the STB in the Shelby is a single bar...why do anything different than that?

 

More is alway better.
