Its not mentioned specifically, but they use those cages for their grass roots motorsports. I'll try and get more detailed info.

Yeah, but grassroots motorsports means it is an event that is organised by the competitors and controlled by the competitors or the track organisers rather than a motorsport body. At this level, a roll cage is not mandatory, and so you can use non-approved cages. It's the equivalent to a Wakefield open day! You can use broomsticks as a rollcage and the Wakefield officials won't even bat an eye as it is not inspected.

Actually no...Grassroots motorsports is not the same as a track day.
Grassroots motorsports would equal your CAMs organised hill climbs, supersprints etc.

If you tried to use a Cusco cage for CAMs affiliated Supersprints, you'd probably not be allowed to race, even though you don't have to have a roll cage for that class.

Here's a site showing Cusco rally teams using Cusco cages.

But to your point, Cusco themselves have said that some of their cages arenot suitable for Motorsport.

ahhh, looking at those pics, the bottom left car is most cirtainly not using the cage we are talking about, look at the triangulation in the main hoop. They may be using cages made by cusco, but im absolutly cirtain its not this bolt together cage we are talking about. no rally driver would drive a car with such a basic cage, not to mention no regulations would allow it for serious rally competition anywhere in the world. Show me a pic of the cage we are talking about, in a proper rally car.

Thanks for the link. I checked the parts they used, and their rollcage is the Cusco Safety 21, which is FIA approved. I'm not against what you say and such. The only info I want to pass on is that the standard Cusco rollcage is not approved by any motorsport body. For some reason, people believe that the Cusco is a proper rollcage that will save their lives. They should be going for at least the Cusco Safety 21 model.

and in the top right pic of the cusco rally car, i can see some more triangulation through the left hand side window, which dosnt seem to be a part of there bolt together cage.

:thumbsup:

sorry if it seems like im picking on you e240, i just see little value in cusco's cute little standard cage, when a proper cage is not much more expensive, yet so much more advanced.

Don't worry...I can take it. :-) I am considering a cage myself as I may be bumped into a higher class for next years supersprints (due to an engine swap :-( )

So if I'm going to be wrong on cages, I rather be wrong now.

:thumbsup: yeah good point.

I went around looking for people to spot weld my chassis and polyurethane fill my rails and 2 people I talked to said it wont offer me any better handling or any improvement, and that spot welding is primarily done such that with firm suspension and massive amounts of grip, they don't rip the original welds open?

True? Not true?

You want seam welding not spot welding. Correct terminology helps :)

Seam welding will stiffen the entire car.
