Project GD STI: Getting Rid of Chassis Flex with Cusco


The lower bracket is bolted down, and the triangulating parts are installed.

The triangulated strut tower brace is now in place. You can see how this is really going to reduce twisting in this area. 

Here, George notches the spare tire cover to clear the brace. 


Now, George cuts the trunk carpet around the bracket for a nice, clean installation. 

What a clean install!

Next, to install the rear frame rail brace, the taillights, rear bumper and rear trunk panels must be removed to install the rear chassis brace.


  1. After installing all the Cusco parts do you think that if you could do it over you’d have chosen Cusco instead of Whiteline for the parts you replaced in “Part One- Rebuilding the Suspension” ?
    I’ve looking to do the same suspension things to my 04 STi as you did with with this 05. I’m tempted to be just as snobby as you and go all Cusco. coilovers, bushings, ends, links, bracing, etc.
    Do you think that would be too far and its better that you got KW, Whiteline and Cusco in various parts?
