Ok I spent some time working on this today and hopefully a scrutineer will chime in. <br />
I added some bracing to the rear strut towers. Now this isn't technically part of the cage (correct?) and I used 1" x 0.095". I should be ok right?
I don't remember seein a hydraulic and mechanical parking brake in the top cars. I reinstalled the factory one tonight but packaging the hydraulic unit in with it will be a major chore and its going to be in someone's way I feel like.
