FIA Certificated

Why Choose a Fully Certificated Roll Cage?

FIA Certificated roll cages offer a significant competitive edge over cages built to either MSUK or Minima FIA compliance standards. Engineered with high-performance materials and optimized geometry, they deliver maximum strength with minimal weight — often up to 20 kg lighter than minima-compliant designs, as they are often designed with smaller diameter and thinner gauge tube.

Key Features & Advantages

  • FIA Certificated Designs
    Built in accordance with the latest FIA roll cage homologation regulations. These designs are eligible for both UK and international events.
  • Superior Strength-to-Weight Ratio
    Constructed from high-tensile T45 tubing (minimum tensile strength: 700 MPa), allowing for smaller diameter and thinner wall thickness without compromising structural integrity.
  • Stress-Tested Engineering
    Each design is derived from a 3D scan, FEA tested to verify its integrity, stiffness, and optimal load paths. The FEA testing is completed by an independent FIA test house.
  • Weight Savings
    On certain models, you can see a weight saving of up to 20 kg lighter than equivalent minima roll cages — a crucial advantage in competitive motorsport.
  • Global Acceptance
    FIA certification ensures global recognition and eligibility for competition.
  • Increased Vehicle Value
    Professionally installed certificated cages can enhance resale value and marketability.

Historic

“A piece of motorsport history! Especially in historic racing.” This is the opening statement for your car build, and Custom Cages can help keep to this motto.

When it comes to historic racing, the design of safety equipment like roll cages is crucial for both safety and authenticity. FIA Appendix K sets strict guidelines that allow historic cars to maintain their original appearance and geometry, while ensuring that safety standards meet the necessary requirements.

The simplicity of historic cages compared to modern ones can be attributed to the fact that materials and engineering standards were different back in the day. The emphasis was more on protecting the driver from certain types of crashes rather than achieving the multipoint designs of today’s standards.

In historic motorsport, the goal is often to balance modern safety standards while still maintaining historical accuracy. Modern cages are more robust, but they don’t necessarily replicate the way cars were originally reinforced, which can affect the authenticity of the driving experience.

Weld-in cages are still acceptable under the current rules, which is a plus for many restorers and classic drivers, as they provide a strong, period-appropriate safety solution.

A roll cage design must comply with the MSA/FIA technical regulations published in the MS UK Blue book. It is the competitor’s responsibility to ensure his/her roll cage complies with the technical regulations appropriate to the event they are competing in.

For more information on the Certification processes, please find our Certification Guide for more details.
