Road use Roll Cages

Road cages are made to the same exacting standards as competition cages, using the same high grade materials. However they are often not as complex, but will usually still offer substantially more protection compared to a standard vehicle with no cage at all.

Often for road use, just the rear (or 'half') cage is used although many people still fit a full cage as this enhances the 'look' of the vehicle. This can be further improved by fitting extras like door bars, competition harnesses (a harness bar may be advisable), fire extinguisher etc.

For the majority of the cars used in motor sport we offer the following roll cage options.

6 point bolt-in cages (bolts to the floor in 6 places)
Multi point bolt-in cages. This is essentially an upgraded 6 point with additional attachment points to the body
Weld-in cages. These cages are sold as kits with all tubes bent & profiled as required and they include all mounting brackets and plates

Bolt-in cages are normally supplied in finished in a hard wearing black powder coating.
Weld-in cages are always supplied unpainted.

Motorsport / Competition Roll Cages

Motor sport roll cages have to conform to the rules as outlined in the certification section. The choice of material is therefore very important. Safety Devices mainly use high quality Cold Drawn Seamless Carbon Steel (CDS Carbon Steel) or, for some applications, T45. CDS Carbon Steel is used to manufacture all of our standard motor sport and 4 x 4 roll cages as it conforms to FIA material specification requirements and offers good elongation and weld-ability, which are key.

Initially used for aerospace applications T45 has for a while now been used in the manufacture of roll cages by Safety Devices.

The advantage of T45 is that it has a tensile strength of approximately twice that of CDS and therefore we can manufacture the roll cage using tubing of the same diameter yet a thinner gauge (wall thickness).This means a substantial weight saving of approximately 0.5 kg per metre of tubing. However this does come at a cost, as T45 is substantially more expensive. Therefore it is only really required by competitors competing at the higher end of the motor sport spectrum.

Roll Bar and Roll Cage

Wide range of roll bars available for wide range of cars, from street to competition use.

40mm chrome moylbdenum pipes used 33% lighter than a similar steel roll bar
Lightweight joints used increase safety with competition roll bar layout
Mounted such to increase body rigidity
Our bar layout is designed from extensive experience. Bar structures based on feedback from the track that looks as good as it's effective.

Price is set by roll bar type, not car type*

* Seating capacity may be restricted on some roll bars
* There are two types of rollbars. Please ask.
* 8 point roll bar may not be fitted on some cars
* Some chrome molybdenum roll bars are not for competition


4 Point Type 10.5kg	5 Point Type A diagonal pipe added to the 4 Point Type 12.8kg	6 Point Type Roll bar with additional frontal portion 18.6kg


7 Point Type 6 Point Type with added diagonal pipe 20.9kg	8 Point Type 7 Point with added rear bar for higher lateral ridigity 23.2kg

4 or 7 Point Roll Cage

	Choice of 4 point or 7 point cages Race specification seamless tube Weatherproof powder coating
The 7 point roll cage for S2000 is the same specification used by Spoon S2000 race cars in the SuperTaikyu series. The soft top cannot be used with the 7 point roll cage; the hardtop can be used with some modification. However, the 4 point roll cage is intended for sport/track driving and can be used with both soft top and hardtop.
