Similar. Easier on the plywood with a router vs trying to chamfer foam.

It had to do with the stiffness. The plywood would cause the front of the car to porpoise at 140mph (quite scary) because the plywood would flutter.

I’m sure the front of the plywood splitter would be pushed down at speed instead of the front end.
