I think he's completely missed the boat. Triangles?
Everyone knows that the ellipse is where it's at. Think about it....just when you needed a bit more clearance, all you need to do is give 'er a little more throttle till the wheel rotates and you gain instant axle clearance. "thumbsup"
We tested ellipses and pentagons. The problem is the gyro effect kicks in when you add more than 4.5 oz to each wheel with an ellipse. If you run anything but a triangle you begin to lose stability when on off camber situations greater than 37 degrees. It is along the same theory though.
