This is a faithful re-imagination of the later RS500 cages.
Made as the original in 25CrMo4 using the original geometry.
Eligible for FIA events
Authentic lightweight design
FORD Sierra Cosworth ‘Factory Style’ Multipoint 25CrMo4 roll cage kit
FIA Compliant:
The roll cage has been made to the FIA prescribed tube sizes. This means the cage was made to comply with all the current regulations. These cages are eligible for all FIA sanctioned events.
Multipoint (weld-in) roll cage: These have a minimum of 8 point attachments. Please note, HOWEVER – Because our roll cage will fit very closely to the body-shell it would be normal practice to weld the cage to the shell in at least an additional 8 or 10 places, (and sometimes many more) making a minimum of 16 points.
Weld-in roll cage kit: Our weld-in kits are supplied with all the parts you need to fit a roll cage. All the tubes are pre-cut and profiled to fit. They come complete with the footplates that get welded to the car, as well as all relevant gussets.

Roll Cage Kit Contents
Your roll cage arrives shrink-wrapped in durable black plastic. And by the way, it is very heavy!
Inside you will find:
- CNC formed tubes for the main hoop, A pillar hoops etc with square and profiled ends are necessary.
- Straight tubes with profiled ends ready for welding into place.
- Set of footplates.
- Check list (every tube has an identifying sticker) so you can be sure you have a complete kit (we will have already have checked that you have the right tubes twice before the kit is packed).
- Instructions sheet.
- CD showing the fully fitted roll cage.
Roll Cage Certification
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).
A roll cage design must comply with the MSA/FIA technical regulations published in the MSA 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.
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 MSA/FIA Certificates
