What type of roll cage you need will depend upon the motor sport discipline you want to use the car for. One size does not fit all! The FIA rules ensure a minimum safety standard but, importantly, the rules also govern the number of attachment points and degree of strengthening for different types of motor sport.
Bolt-in roll cages are easier to fit because you will not need to be a skilled welder, the tubes are powder-coated so do not require painting and the cage can be removed at a later date if you need to.
Professional teams will always fit weld-in roll cages in order to achieve the best possible bodyshell rigidity and safety protection. A weld-in cage will always be lighter than the equivalent bolt-in design. The FIA and MSA regulations permit all roll cages to be welded in, however the number and type of fixing points has to meet the regulations for your chosen class of competition. For instance, a 10 point, fully-reinforced roll cage for a World Rally Championship rally car or a BTCC saloon would not comply with FIA rules for historic cars which are allowed fewer mounting points.
For some models a bolt-in design is offered as an alternative to the normal weld-in cage. Often this is more appropriate for historic vehicles where the owner may wish to be able to remove the roll cage.
There are four basic designs, however refer to the model diagram for exact specification as it varies by model and ‘Tube by Tube section’ for detailed explanation.
6 point weld-in roll cage with door bars and lateral support bars in the main hoop and between the A pillars.
Higher specification includes cross doors bars, cross diagonals, tunnel brace, harness tubes and triangulation tubes to front struts. Eligible for most events (non-historic) including internationals.
Eligible for all international events specification includes main hoop cross, cross in roof section and screen pillar support tubes.
Complies with new international regulations includes cross in main hoop for additional strength, cross in roof section and screen pillar support tubes. Hans™ device compatible with almost all types of roll cage that has seat harness tubes.
Alternatively: Club Cages
Club roll cages are aimed at the budget-focussed competitor building a car where a complete ‘off-the-shelf’ cage is more than is required. You can fit as many or as few tubes as your regulations allow. The range of four kits, plus the ability to purchase straight lengths of tube for bespoke designs, means Club Kits perfectly meet the demands of competitors keen to customise the roll cage to thier needs.
