Built specifically for the four-door E36 and M3 shell, this BMW roll cage is an International Multipoint T45 kit supplied with FIA certification for eligible UK and international competition. For drivers preparing a BMW E36 roll cage around a 4dr chassis, the important point is that this is not an adapted two-door layout: it is engineered around the four-door shell and its own structural requirements.
The cage uses high-tensile T45 tube with a minimum tensile strength of 700 MPa, in a reduced-diameter, thinner-gauge specification designed to trim weight without giving up structural integrity. The design process starts with a full 3D scan of the E36/M3 chassis and is refined through independent FEA testing before manufacturing begins, giving the final kit a strong engineering basis rather than a generic fit.
Every tube is laser profiled and CNC bent so the cage can be installed with the accuracy needed for a permanent weld-in structure. We manufacture the kit in-house using CNC laser-cut and end-formed tubes, laser-cut and folded footplates and gussets, with production supported by our laser cutting services and CNC tube bending capability. A weld test sample is included so your welder can demonstrate competency before starting on the cage.
Designed, manufactured, and certified in-house at our Daventry facility. Declaration forms and fitting guide are included. For specification advice, FIA eligibility checks, or installation support, email sales@customcages.co.uk, call 01327 872855, or visit our contact page.
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
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.
