A roll cage is a safety feature installed in a vehicle and is used in environments, where a high danger of rolling is likely, such as car racing. The idea behind a roll cage is that if the vehicle rolls, it will protect the occupants. While parts of the vehicle are damaged or crushed, the roll cage prevents damage on both of the driver and the passenger compartment, creating a safe pocket. This safety feature is designed to work with other safety features, such as crumple zones and seat belts to ensure protection in accidents. Installation of a roll bar also has another major benefit, which is to stiffen the chassis of a vehicle. A stiffer chassis is equivalent to better handling, braking, and overall feel of driving experience.Fit 89-05 Mazda Miata MX-5 (MX5)
