I just got the Tokico D-Spec shocks and struts with the Eibach pro kit and the shop that installed it for me said that if I got a Strut Tower brace it would make handling better, especially around curves. Is this true? Or is he just trying to sell me something?
It has little benefit on new Mustangs. Ford took care of that with proper design. Notice that Multimatic does not use one on the FR500. No one knows more about the new Mustang than they do.
The 2005 is supposed to be as rigid as a 2004 with a cage. I have a Steeda STB (the one with the stupid rose-jointed ends) and can't detect a difference. When I fitted a STB to my '98 Camaro, you could tell instantly.
I doubt that a strut brace with thsoe rose-jointed ends would do anything. Such a brace would only do anything if the forces were exactly on axis to the brace, which is unlikely.
To tell any difference it would have to be a rigid brace.
Again, there is one on the GT-500 in the under hood shots I've seen. Yes the new Stang's unibody is much more rigid than the old one, but there may be room for improvement.
