Safety Devices Ford Sierra Roll Cages Updated
Roll cage news, November 2025
The Ford Sierra is still one of the great British motorsport cars, from RS Cosworths on track days to Sapphire rally cars and restored road projects. If yours is being built for competition or regular track use, a proper roll cage is one of the first things on the list.
We have just been through our Safety Devices Ford Sierra listings. Each one now shows the model it fits, the design options and the approval information clearly, and the rear cages have their own listings so you can buy one without the front section.
- Safety Devices cages for the Sierra three door, five door, Sapphire and Cosworth models
- Bolt-in six point cages and a CDS weld-in cage
- Rear cages listed on their own, with single diagonal, harness bar or cross diagonal options
- Door bar options on the full bolt-in cages
- Bolt-in cages come in black powder coat as standard, with other colours available
- Each listing shows whether that cage is homologated

What the Sierra range covers
Safety Devices make cages for most of the Sierra family, and we list them by body style because the shells differ. There are bolt-in cages for the three door Sierra, the five door with or without a sunroof, the four door Sapphire, the Sierra Cosworth, and the Sapphire 4×4 and Sapphire 4×4 Cosworth. The body style and sunroof matter, so check the listing title against your car before ordering.
Each listing now sets out the model and years it fits, the cage number, what each option includes, and whether that cage is homologated. That makes it much quicker to see which cage suits your car and your plans for it.
Design options and rear cages
The full six point bolt-in cages are offered with a single fixed diagonal or cross diagonals in the rear section, with or without a harness bar, and with or without door bars. The door bars bolt to the front and rear sections, so they need the full cage.
From this update the rear cages are listed on their own too. A rear cage can be used alone, and comes with a single diagonal, a single diagonal with a harness bar, or cross diagonals with a harness bar.
The bolt-in cages are finished in black powder coat as standard, with grey, blue, silver, white and red as alternatives, or unpainted by request. The CDS weld-in cage for the Sierra and Sapphire is supplied unpainted and oiled, ready to be welded in and painted to suit the car.

Bolt-in or weld-in
Bolt-in cages fix to the shell with mounting plates and bolts, and can be removed later if the car changes role. They suit track day cars and club competition cars, and many owners start with a rear cage and harness bar and add the front later.
The CDS weld-in cage becomes part of the shell. The Sierra and Sapphire weld-in cage includes cross diagonals, upper and lower backstays, a rear strut brace and tunnel brace at the back, and a roof diagonal, dash bar and triangulation to the bulkhead at the front. It is the one for a dedicated competition car, and it needs a fabricator to fit it properly.
Whichever you choose, check your championship’s rules and speak to your scrutineer before you buy, because the approval your class asks for is what decides. Our guide to roll cage installation for track cars covers the fitting side.
Seats and harnesses to go with it
A cage with a harness bar gives your harness shoulder straps a proper anchor point, which is why so many Sierra owners pair a rear cage with a bucket seat and a harness at the same time. Garreth’s advice is to plan the three together: the seat position decides where the harness bar needs to be, and the cage options decide which harnesses will fit. Tell us the exact car and what it is used for, and we will put the cage, seat and harness list together.
