The skid block was introduced as part of the safety changes that followed Ayrton Senna's death. The block is usually made of a material called Jabroc. Jabroc is made of beechwood and built in a composite process. Veneers are layered and a high strength resin is used in each layer. They are pressurized and pressed, and brought to a certain and very consistent material density. As a result, each Jabroc skid plank is all but identical in terms of wear rate and material density.
The plank does not in itself restrict airflow under the car. It is used as a gauge which restricts the minimum ride height attainable by the car. The closer the car is to the ground, the more efficient the front wing and rear diffuser. The higher the down force levels, the faster a driver may corner. Cornering loads can push the car down much lower to the road, which can be dangerous and so the skid block was introduced to counteract this. The thickness of the plank is one of the parc ferme tests. If it is found to be worn beyond the allowed limit the car is disqualified.

For us amateur racers, it's the stuff that protects the expensive carbon fiber...:wink many times as you go in and out of the pits you can hear the bottom of the car scrape over uneven transitions and these jabroc wear points rub instead of the aero parts on the car.

so here is a question... Should we add these blocks to our NFGT's just like we are adding X-pel clear-film, GTGuy Gravel Screens etc??
