MAZDA RX7 MK3 FD 6 point National Spec CDS roll cage kit. MS UK Compliant

Cage Information

National Range (6 Point Roll Cage):

Our ‘National’ cages are fully MSUK compliant for both Race and Rally (and just about all other disciplines as well).

A simpler and more cost-effective safety cage than our FIA-certificated or Multi-point cages but with our second-to-none quality and fit.

The drawbacks would be they are heavier than an FIA / MSUK certificated design (average 15 to 20 kgs) and don’t add as much bodyshell stiffness as there are fewer mounting points.

These are manufactured from high-quality CDS (Cold Drawn Seamless) tube with a minimum tensile strength of 510 Mpa (although T45 can be specified at extra cost).

The 6 point National spec. roll cage exceeds MSUK requirements
Based on our full multipoint cage design to ensure quality of fit
Weld-in for reduced weight and improved stiffness compared to a bolt-in cage
All tube is high quality CDS (510 Mpa) steel tube – 45 x 2.5mm
Hoop Lateral tube and Dash bar for improved side impact protectio
Driver and co-driver harness tubes
A Pillar supports complete with gussets and Rear diagonal
Crossed door bars complete with gussets
Roof diagonal (or cross as an option)
Kit includes all footplates
Simpler to install than full multipoint cage
Customers may have to check seat belt angles and trim harness tubes accordingly. Recommended angle of belts as per MS UK Blue Book specifications.
To upgrade cage with gussets etc see Accessories
Extra lengths of tubes available in 1.5m to add tubes to the design.

MSUK Compliant – See our ‘National’ range:

The roll cage will be made using the minimum MSUK prescribed tube sizes – thicker gauge than we would use in a certificated design, and, so (unfortunately) heavier.

Usually, these are manufactured from CDS (Cold Drawn Seamless) tube – ours is a high tensile material with a minimum tensile strength of 510 Mpa – although T45 can be specified at extra cost.

These cages are eligible for all MSUK events.

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.

Roll Cage Certification

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.

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
