Correct me if I'm wrong, but is that an Extra Strut bar going back to the firewall.
Is that for better ridgitity or is that part of the roll cage?
I had a HSV with some pretty serious suspension on it. The Brock shop said that any strut brace that wasn't braced against the firewall was more show than go.
The one they put on my car went on an angle back to the firewall, then travelled along the firewall, then back out on an angle back to the other tower.
I haven't seen one this shape for the Beast yet. When I saw this photo, it reminded me of what they said about it needing to be braced against the firewall to be most effective.
