The certification process generally allows for a lighter roll cage because it is a bespoke design where the diameter and thickness of each tube is optimised to achieve the overall strength required by the FIA/MSA rules.

Custom Cages’ roll cage kits include a weld test sample. Once completed these are returned to the company for load testing. They are subjected to a physical test to assess the actual yield strength of the weld. This ensures that the self-fit roll cages achieve the highest standards of integrity.

Effectively, the MSA is governed by the FIA so if a roll cage design complies with FIA regs, then it is also eligible for MSA events.

In order to compete in MSA/FIA events every vehicle, which has a certificated design of roll cage, should have a copy of a valid certificate to present at scrutineering. Custom Cages has certified the majority of popular roll cages. All other roll cages comply with MSA/FIA regulations and receive a Letter of Conformity for competitors to present to scrutineers.
