mender Posted March 7, 2018 Report Share Posted March 7, 2018 I did mine according to the rules, then added extra structure around the cell plus an extra layer of steel under the car and on the side for even more puncture resistance. Two layers of steel protecting the bottom of the cell and three layers of steel on the "exposed" side. The door is plastic so I added thick sheet metal to the NASCAR door bars. One of my design goals is to be able to jack up the car using the structure supporting the fuel cell. Link to comment Share on other sites More sharing options...
