The Latest Safety Devices Nissan Roll Cage Lineup And Definitive Guide.
Roll cage guide, December 2025
Safety Devices have made roll cages in the UK for decades, and their Nissan range covers a mix of cars that are still being built up and raced: the Skyline R32, the Sunny GTI-R and Pulsar, the Micra Mk2, and the Datsun Z cars that came before them. Heading into the 2026 season, this guide sets out what is available for each car.
It goes car by car, explains what a rear cage and a full cage each give you, and covers harness bars and fitting. If you know how your Nissan will be used, it should get you to the right part number quickly.
- Safety Devices cages listed for the Skyline R32, Sunny GTI-R and Pulsar, Micra Mk2 and Datsun 240Z and 260Z

- The Sunny GTI-R cage comes for single or cross door bars
- The Skyline R32 cage is a CDS weld in cage for a car with no interior trim

Rear cages and full cages
Most Safety Devices cages are built in sections. The rear cage is the main hoop behind the seats with backstays to the rear of the car, usually with a diagonal and often a harness bar, and it can be fitted on its own. The front cage runs forward along the A pillars and must be used with a rear cage. Door bars complete the full cage and need both.
A rear cage suits fast road cars and lighter track day builds, where a harness bar and some extra stiffness are the main reasons for fitting one. A full cage ties front and rear together, protects the front of the cabin as well, and makes the shell much stiffer. It is what most competition cars need. Because the sections are separate, a car can often start with the rear cage and have the rest added later.
Nissan Sunny GTI-R and Pulsar
The GTI-R has the most complete Safety Devices range of the Nissans. Cage D032 is an 8 point multipoint bolt in cage, developed on an imported car. The rear cage has a cross diagonal, a strut brace, a harness bar and B post mounting points, and it can be used alone.
- For single door bars: front cage RBD032 3SSU, rear cage RBD032 5SXU and single door bars for each side.
- For cross door bars: front cage RBD032 3SSX, rear cage RBD032 5SXX and cross door bars for each side.
- Rear cage only: RBD032 5SXU, with the cross diagonal, strut brace and harness bar.
Cross door bars give more side protection, but take up more room, so think about getting in and out if the car still sees the road. If you are also doing the seats, our guide on fitting Sparco reclining seats in a Pulsar GTI-R covers the brackets.
Nissan Micra Mk2
For the three door Micra Mk2, 1993 to 2003, Safety Devices make cage D028, a bolt in design. The full cage is a 17 point cage with cross door bars. The front cage goes through the dashboard, and the rear has cross diagonals, a harness bar and a tunnel brace.
The rear is also sold on its own, in two forms: RBD028 5SMX with a cross diagonal and harness bar, and RBD028 5SMU with the cross diagonal only. If you plan to mount harnesses to the cage, choose the one with the harness bar. Both can be used without the front cage. Safety Devices sell the D028 as a homologated design, and a homologated cage must not be drilled, cut or welded, so do not modify it to make it fit.
Nissan Skyline R32
For the two door Skyline R32, 1989 to 1994, without a sunroof, Safety Devices make cage D045: a CDS steel weld in cage with cross door bars and a roof diagonal. It is designed for a car with no interior trim, and the front cage goes through the dashboard. This is a competition cage for a stripped car, not a road car upgrade, and it has to be welded in by someone qualified to do it.
For many owners the harness bar is the most useful part of a cage. Harness shoulder straps have to run back from your shoulders at the angle the harness maker specifies, and a bar across the cage is usually the only way to get that in a car. Taking the straps down to the floor behind the seat pulls them onto your spine in an impact.
Most of the rear cage options here include a harness bar. Check which one when you order.
Datsun Z cars
The Datsun 240Z has Safety Devices cage D004 in a USA specification, a 6 point bolt in cage that clears the normal trim and dashboard, with front, rear and single door bar sections, and the rear cage alone. The 260Z two seater takes the D004 rear cage, with single diagonal, single diagonal and harness bar, or cross diagonal and harness bar options. There is no front cage for the 260Z, and Safety Devices list that rear cage as not for competition use.

Fitting a cage properly
A cage only protects you if it is fitted well. We recommend a professional fitter for any Safety Devices cage. They will position it correctly, make sure every mounting plate sits flat against the shell, and tighten the fixings properly, so there are no gaps or stress points. A weld in cage must be welded by someone qualified and experienced with cages.
Many of these Nissans are now thirty or more years old, and a lot are imports, so check the metal around the mounting points before you order. Cages come in black powder coat as standard, with other colours at a surcharge. Garreth’s advice is to tell us the car, its year and whether it has a sunroof or its interior trim, and how it will be used, and we will confirm the part numbers. For anything about competition eligibility, ask your scrutineer.
