Roll Cage Options For A Track Driven Triumph TR7
Customer question, Triumph TR7
A caller this week with a Triumph TR7 he wants to use mainly on track, but he still wants to drive it there and drive it home. What cage should he be looking at?
It is a good question and it has more than one right answer, which is why Garreth is ringing him back with prices instead of us guessing at a spec over the counter. Meanwhile, here is the same walk through the options that Cameron gives on the phone, because the TR7 is better served than most classics and the choice comes down to three things: which body you have, how far forward the cage goes, and whether you want a bar across the door.
- First question is body shape: the coupe and the soft top take different cages
- Bolt-in rear cage from £452.40, full six point bolt-in £932.40, weld-in multipoint £2,274.00
- Safety Devices list the soft top rear cage with a diagonal for competition or without one for road use
- The coupe rear cage can be run on its own, and the front half added later
- Door bars are an option on the full cage, and they are what make a road driven car awkward

First, which TR7 have you got?
This decides everything else, so it is the first thing Cameron asks. The TR7 was sold as a fixed head coupe and later as a convertible, and Safety Devices build a different cage for each. The coupe cages are cage number N008, the soft top is N015. They are not interchangeable and there is no sensible bodging between them.
If you have a TR8, the same cages cover you, which is handy because the parts are shared.
How far forward do you want it to go?
A rear cage is the hoop behind your head with its legs down to the floor and back to the wheel arches. A full cage carries on forward, up over the dashboard and down to the floor by your feet. On the TR7 coupe you can buy the rear on its own and add the front half later, which is the sensible way to do it if the car is going to get faster over a couple of seasons.
The rear hoop is the part every option here has in common. What you add in front of it, and whether you add a bar across the door aperture, is the whole decision.

The Safety Devices cages bolt to the floor and the rear wheel arches, clear most of the trim, and our listings carry FIA and MSA approval on them. On the full coupe cage the front section goes through the dashboard and down to the floor, so it is a proper afternoon’s work and not a bolt-on.
The Custom Cages kit is a different proposition: a weld-in multipoint, minimum eight points, made in the UK from T45 tube, laser profiled and mandrel bent to the shell, and supplied in bare metal with powder coat as an option. It is listed as MSUK compliant and it is built for cars that compete. Garreth’s honest read for a road driven track car: unless the championship you are entering pushes you there, the money is better spent on the bolt-in and a decent seat and belts, because a weld-in also means a stripped interior and a welder.
Will it be accepted where you are going?
Here is where we stop short of telling you what you want to hear. Trackdays and competition are not the same thing. For an open pit lane trackday the organiser sets the rules, and plenty are happy with a good bolt-in rear cage or no cage at all. The moment you enter something with a championship attached, that championship’s own regulations decide what is acceptable, and they are the document to read before you buy anything.
So tell us what you are entering, or that you are not entering anything yet, and we will spec accordingly. What we will not do is tell you a cage is legal for an event we have not read the regulations for.
Common questions on TR7 cages
Can I fit a cage and still use the car on the road?
People do it constantly, and the TR7 cages are designed with it in mind. Safety Devices list the soft top rear cage with a fixed diagonal for competition or without the diagonal for road use, so the choice is built into the product. What we would not do is give you a legal opinion on your particular car, because that is not our job.
Do I have to have door bars?
No. On the full coupe cage they are one of the design options, so you pick. On a car doing road miles most people leave them off and take the harness bar instead.
Can I start with a rear cage and add to it?
On the coupe, yes. The rear section of the N008 cage is listed as usable without the front cage, so you can buy the rear now at £572.40 and add the front later. It is the route we would suggest for a car that is going to develop.
Bolt-in or weld-in?
Bolt-in for a car that still lives on the road, weld-in if you are committing the shell to competition or your championship asks for it. The weld-in also wants a stripped interior and a competent welder, so the £2,274.00 is not the whole cost of it.
Is the TR8 the same?
Yes, the Safety Devices TR7 cages are listed for the TR8 as well, coupe and soft top alike.
What will you need from me to quote it?
Whether it is a coupe or a convertible, what you are actually entering if anything, and whether you want door bars. That is enough for Garreth to come back with a price and a sensible spec.
