Project GD STI: Getting Rid of Chassis Flex with Cusco

,

The main issue is that the rear brace mount needs a spacer due to the Whiteline anti-lift kit, lowering the area where the front of the brace bolts on to the subframe.
 

Howard machined these awesome aluminum spacers for us, although you could also use washers if you are not as baller as us!

 

 

George removes the under car aero panels to install the mid chassis braces.
 

With the panes removed, George test fits the braces. 
 

The braces use all existing holes. The middle hole doesn't have a nut, so Cusco supplies the nut with a pre-attached long handle so that you can reach in and position the nut.

The handle also acts like a doubler and improves the local stiffness of the sheet metal in this area, a nice touch.

  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?
