Project GD STI: Getting Rid of Chassis Flex with Cusco

  • Mike Kojima

,

It immediately became apparent that the new Cusco brace was going to interfere with our Radium engineering catch can, sigh.

Our solution was to keep the existing bracket for the catch can and simply drill new mounting holes slightly lower on the shock tower. So much for the all bolt in catch can, but it was easy to drill holes. We did not have this issue with our old bar. 

 

Now we are cooking after we relocated the catch can; everything fit great. 
 

To install the trunk brace, the rear seat must be removed. It only takes two bolts to do this.

 

With the seat out, you can loosen the strut mount bolts to add the rear brace brackets. 
 

The brackets are attached to the crossbar and bolted to the top of the strut towers. 
 

The positions measured and the holes drilled for the lower mounts of the brace.

    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?

      I like the Cusco braces but prefer the other brands for those parts, especially the shocks.
