Our design has greatly simplified the roll cage, as well as maintained the same level of safety. In total, we took out 18 welds and 8 bends from the 106 welds and 26 bends total. That corresponds to a 17% decrease in welding time and a savings of 14 ft of material!
Here are side-by-side views of the major changes:
Per roll cage, we saved about $153! That could amount to a $153,000 annual savings for Arena Racing if they reach their goal of selling 1,000 annually. We are really proud of our work.
Also, the safety of the driver nor the integrity of the roll cage were compromised. Here are the stress analysis to compare:

We worked really hard to achieve this over Spring Break. Here we are in the West Hall:
