My first concern would be it's immense stiffness, but I guess they've got good reasons to do it!
Perhaps flex in a car makes the bite oscillate - so less flex could mean more consistent bite (which on carpet and high bite astro tracks is more important than the amount of bite)? Just thinking of theories here though, I'm no scientist and my racing experience goes back... 1 season!
I love the looks of the car - not just the elaborate CNC work, it's construction deserves appreciation
And it's keeping the glory of belt drive very much alive
