While not the most graceful looking race car, the beauty of the 2J was in its function. 
The source of the downforce.  The Rockwell snow mobile motor drove two fans that sucked the 2J to the ground.  Downforce was in the region of 1500 lbs. 
Here we can see the snow mobile motor perched above the transmission.
