Things to Know about Roll Bars Roll bars, also known as roll cages, are a very important component in cars as they cushion the body from jerks and yanks during an accident. However, before picking roll cages for your car, you should take into account all the nitty gritties, and a few on them are listed below: The most important thing to remember is that either your head or the limbs can come into contact with roll cages. So, having a padding on the rolls bars is essential to avoid mishaps like broken bones and fractured skulls. Hard core racers should go for roll bars with high density padding. For others, even a low density padding will be sufficient. So, review all the different padding materials available as the variety you choose should not bend, burn or squish. If you are going for roll cages designed for race cars then there are a couple of things that you should keep in mind. Most of the race cars don’t have back seats, interiors and various other detailings generally provided in passenger cars. So, they are not designed to accommodate arm rests, rear seats and other conveniences. While, the roll cages for race cars are primarily constructed to provide safety and will therefore have a completely different modelling. Various factors have to be considered while installing roll bars and cages in any car. These are the interiors of the vehicle, size of the driver, seat height and many others. So, picking longer roll bars is always better as it will be possible to cut them and give them a better fit. Most of the factory notches have 90 degree joints on one end but their other end also needs to be cut. On an average, most shops charge around $100 per point for the installation of a roll cage. So, for a 6 or 8 point roll bar, you will have to shell out around $600 and if your car has fully equipped interiors then you might also have to pay a little more than this. The cost of a chrome Moly roll cage will be twice of a mild steel cage. Even its installation will be double the price because it has to be tig welded and not mig welded. But if you want to cut down the expenditure by a few pounds then go for mild steel and if you don’t mind paying a few extra bucks then stick with Moly. However, there isn’t much difference between the two as the wall thickness of moly is less than that of mild steel. In any case, Moly is more suitable for weight savings however it doesn’t provide additional strength. Street cars or dual purpose cars don’t really need roll bars and cages. So, the chances of sustaining injuries during an accident actually increase when roll bars or cages are installed. So, they should be installed only if you are wearing a helmet or a full harness. On the other hand, a majority of the race cars are fitted with atleast one anti roll bar. In fact, anti-roll bars are a simple and effective way to fine tune the handling characteristics of any race car. But still, many times, they are used incorrectly and their function is not understood accurately. So, taking some time to understand what type of roll cages will fit your car best helps immensely and will guide you during the decision making process.
