Roll cages provide important safety benefits for racing and high-speed driving by protecting the driver and enforcing the chassis. They prevent roll-overs and collisions from causing serious injury or death. Additionally, roll cages increase chassis rigidity and reduce flexing, which improves handling by maintaining optimal suspension geometry even during high lateral forces. Proper roll cage design is important for the type of protection needed, as higher point cages offer more coverage from side impacts in addition to rollovers. Due to these safety benefits, roll cages are often required for motorsports.

2. Roll cage’s are probably some of the most important safety devices when it comes to racing, stunt demos, monster truck races or anything that puts your life in danger when it comes to motorsports. Roll cage’s have prevented many deaths and fatal injuries that may have occurred if the roll cage was not there to protect the driver. Roll cage’s do more then just protect the driver: it also protects the chassis. What do we mean by that? Roll cage’s enforce the chassis giving it a more rigid brace reducing the amount of suspension geometry change. Why do we need to stiffen our chassis? How do roll cage’s bring more safety to the drivers? http://www.autonest.org/modifications/roll-cage-design-basics

3. As stated in the previous paragraph, roll cage’s increases the amount of rigidity the chassis has. Why is this important? Whenever your car goes through a sharp turn at high speeds, it undergoes a certain amount of lateral gravitational forces. This gravitational force can introduce high amounts of stress towards the vehicles chassis. This stress and cause the vehicles chassis to undergo chassis flex, which can be reduced my roll cage’s. Why do we want to reduce chassis flex? http://www.autonest.org/modifications/roll-cage-design-basics

4. Chassis flex can have detrimental effects on your vehicles suspension and handling. What exactly does it do? Chassis flex can cause the suspension’s geometry to change. Remember the optimal camber you set on your vehicle for the perfect amount of tire grip? Chassis flex can change that camber degree into something even worse causing the handling to suffer. It can also change the other suspension alignments like toe and caster. That is no joke! Thankfully roll cage’s add the extra benefit of chassis rigidity. There are other tools and techniques you can do and/or use to create a much wanted stiffer chassis. Other tools like strut bars and techniques such as stitch-welding. http://www.autonest.org/modifications/roll-cage-design-basics

5. Another added benefit of introducing a roll cage to your vehicle is the increased amount of safety that comes with the ride. One thing many people should understand about roll cage’s, though, is that not all of them protect you from t-bones, or side collisions. There are point systems when it comes to a roll cage. The normal manufacture produces some that go, on average, from a four point system all the way to a fifth teen point system. A four point system will protect you incase of a roll over or dangering high speed wall-collision but unless your roll cage has side bars: you will not be protected in case of t-bone. http://www.autonest.org/modifications/roll-cage-design-basics

6. So, from roll overs all the way to chassis rigidity and reduction of chassis flex, the roll cage has very important functions and jobs when it comes to your vehicle. Because of these reasons, mainly safety alone, many motorsport sanctions require each and every vehicle to have a certified race legal roll cage to prevent any serious, or fatal, road injuries from occurring on the race track. Without the use of roll cage’s at races, many deaths may have occurred in the past. http://www.autonest.org/modifications/roll-cage-design-basics
