I spent several late nights thinking about this, and it dawned on me that on a stock a-frame car the full front-to-back braking force is transferred into the rear mounts through the crossmember. The front mount is just for side-to-side stabilty. With the 935 suspension, the front strut rods and mounts now see the full braking force in tension, and if that force is unbalanced, you can rack the front crossmember side-to-side. The main reasons I'm reinforcing the front mounts and adding the x-brace. Over the long term, it may not ever crack or fail in the stock condition, it just doesn't seem stiff enough for a well functioning suspension.

Boy, did I agonize over that decision! I went back and forth several times between the boxed strut mounts and stock mounts. And I still may regret that decision! In the end, I felt I had enough adjustment with the 935 suspension that it would be fine with more street friendly camber settings, and with a little soft putty I can still waterproof the strut tops. And if this setup doesn't work well, I can go back to torsion bars and a-frames, but with a little better reinforced chassis.

I can still squeeze a couple of soft duffle bags in there for a weekend.
