There are 3 main types of roll cages: Bolt in/show, Roll bar/Drag, and Full cage/Time trials/Drift. There are other types, but these are the 3 most common that you will see. All of them have pro’s and con’s but they are all designed to keep the driver and passengers safe in the sad event of a roll over or a heavy accident. Depending on what materials are used, and how in-depth the cage is designed/built, the cage can add significant amount of weight to a vehicle. With the added weight, comes added Safety, and chassis stiffness.
First the bolt in/show cage. These cages are the least safe, most racing bodies do not allow these cages. That is because they offer little roll-over support. They can help a little, but are mainly frowned upon. Many people have the bolt-in cage painted or powder-coated before installation. They are nice since most bolt-in cages work around OEM interior, also they can be removed if necessary.

Second, is a roll bar/drag cage. These typically consist of a main hoop, rear bars and door bars, all welded directly to the chassis. The door bars can swing-out with approved kits. If you go much faster, a more in-depth cage is needed. These offer good roll-over protection, but no side impact protection. Roll bars can typically be made so that all the OEM interior will still fit. These are typically the easiest to get into and out of the vehicle.

Third, is a Full weld in cage. Commonly used in Time Attack, Drifting and most all-out race cars. These can go from a very basic 6 point design, to a more complex 10 point Design. Each sanctioning body has a little variance on the rules of what is allowed, and what is not allowed, So download the rulebook for the series that you plan on competing in before designing the cage. They offer good roll-over protection, side impact protection, and stiffen the chassis a good deal as well. A removable steering wheel is recommended to make entry and exit of the vehicle easy.

Roll cages are designed to keep you safe, but they can hurt you if you are not prepared. OEM Seat belts allow for too much give, so aftermarket harnesses are a must. Some cages are designed so that a helmet is recommended at all times. It all comes down to the position of the driver’s head in relation to any steel Bars.
