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.
Bolt In
Key Features of the Bolt-in Roll Cage Kit:
- Quick Installation:
- These kits offer a convenient way to install a roll cage in a car, especially compared to weld-in kits.
- Installation is simplified as it mostly requires bolting, with welding needed only for the footplates.
- Strength and Lightness:
- Using our FIA Certified Lap-Joints: These lap joints are a key feature, offering stronger and lighter performance compared to traditional fixings. Their design also makes them nearly invisible once the cage is painted.
- Footplate Design:
- Traditional footplate boxes are not used due to their unacceptability in international events, replaced with underfloor doubler plates, which are more robust and secure.
- OEM Mounting Points:
- Some of our bolt-in designs utilise OEM mounting points in the body shell. This method is not suitable for MSUK or FIA-sanctioned events — please contact the technical sales team for further details.
- Fixing Points:
- Depending on the car’s category and model, there are up to 14 fixing points.
- High-Quality Fasteners:
- The kit uses high tensile 12.9 grade fixings, which are strong, durable, and included with the kit.
- Coating Options:
- The kit can be supplied either with a powder-coated finish for extra durability and aesthetics, or in plain steel, which can be customized by the installer.

xWestfield Wide Body según las últimas normativas FIA 2025
Como cualquier propietario te dirá, la experiencia de conducción, la respuesta, la sensación y la emoción que te da un Westfield no tienen comparación
Ruedas abiertas, conducción expuesta... sonrisas por millas
¡Todo esto debe ir acompañado de seguridad! Hemos desarrollado una jaula antivuelco T45 FIA con pernos
Usando pruebas FEA para optimizar tanto el peso como la integridad estructural, incluyendo pruebas de carga lateral para mayor seguridad del conductor, mayor protección contra impactos laterales con barras dobles en las puertas. Las jaulas antivuelco tradicionales se montan en el riel superior del chasis, mientras que este modelo se monta en el riel inferior del chasis, proporcionando mayor protección para las piernas inferiores. También desarrollamos un cruce trasero opcional para los soportes traseros, aumentando la resistencia al abarcar el espacio entre el chasis superior e inferior en la parte trasera, y una barra Petty desmontable para un solo ocupante para mayor protección en caso de vuelco.

Certificación de jaula de seguridad
xA 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.
To compete in any race or rally your roll cage will need to comply with either MSA or FIA regulations. (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). There are some instances where the FIA allows certain design features where the MSA do not (and vice versa).
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.
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.
To obtain a certificate for a self-fit roll cage, the installer must complete a Custom Cages weld test.
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.
Additional samples may be requested.
Certificates will only be issued on completion of a successful test.
Please be aware that there is a charge of £60.00 + VAT for all MS UK / FIA Certificates
