If there are obstructions, measure from those instead. Ensure that there are no obstructions that could get in the way of the sides of the main hoop, though as they should go all the way to the floor. This determines how wide the hoop can be. This refers to the width of the car from side to side. This refers to the height of the car from the floor to the roof, this determines how high the roll cage needs to be 3. Therefore, it is necessary to measure the angle at which your roof meets the side of your car so that you can determine the angle that the tube will need to bend. This is where the roof bar of the roll cage will go, so you need to make sure that there is space for that bar and space for it to start bending down. Measuring properly is crucial for a successful build. You may need to remove the car seats and carpet.Īnother tip before you start building your cage would be to make sure that you have enough room to install it. When using mild steel, you can use a MIG or a TIG welder.īefore you start building, you need to make sure you have enough room to install the roll cage. It is quite similar to steel in strength but is considerably lighter and, subsequently, will not hinder your vehicle’s performance as much.įor the purposes of this guide, we’ll be discussing how to build a steel roll cage however, the process when using chromoly is mostly the same other than the fact that it is advised that you TIG weld chromoly. Therefore, a viable alternative to steel is chromoly. However, steel is heavy and will hinder your performance to a degree if you are using the car for racing. Mild steel is a common choice as a result of its strength, its reasonable price, and the fact that it’s relatively easy to work with. One of the most crucial decisions you’ll make when building your own roll cage is deciding on the materials that you are going to use.
Beyond this, there are 10, 12, and 14-point designs that provide more structural integrity. An 8-point roll cage includes a main hoop, a windshield brace across the roof, a back brace, sides, subframe struts, and gussets. An 8-point roll cage is the most basic and therefore probably the best option if this is your first build. There are a number of roll cage designs that exist for use depending on your needs. An everyday vehicle is unlikely to have or need a roll cage, but sometimes a roll bar is installed to give the driver some amount of protection in the event of a rollover. For this reason, they are also often used in off-road vehicles. Roll cages are predominantly used in cars that are being used for racing and stunt work because of the aggressive driving style and the increased danger. They are typically used to reinforce the vehicle and ensure that the passenger is protected in the event of an accident, particularly if the car rolls.
A roll cage is a metal framework that can be built around the inside of a vehicle.
