Some of the final parts of this cage build are the door bars. The driver side gets curved, NASCAR-style door bars for a little more strength and room for the driver. In the event of an accident in wheel-to-wheel competition, the protruding door bars will give the driver even more room should the impact be hard enough to bend or deflect the cage at all. The passenger side gets the simpler X-style door bars, which are still quite effective in protecting occupants in a crash.
Remember how we said one of the requirements for the cage was to have the hardtop and driver still fit? Well, in order to create some clearance for the cage, the inner layer of the carbon fiber hardtop had to be cut out, which also removed seven pounds from it. In doing this, we also had to create new brackets for the carbon fiber top to bolt on as well. In these photos, you can see the clearance with the inner layer removed and also the new brackets.
