Does any one have a roll cage for a ur quattro (lwb) they want to sell, does not have to be full fia/rac spec as just for track day use, cheers Mark.

ive seen instances where the ends that bolt down shoot thorugh the floor trapping you

as there arent any large square box mounts where they meet the chassis, its jsut liek jamming a peg down through the floor, not enough reinforcement or load spreading

[s4boy]

been looking on the custom cages website and there rac historic bolt in cage for the urq has plates welded onto the inside sill and then cage
bolts to this that is the sort of thing I'm looking at, so it can be removed painted and then refitted, very difficult to spray weld in cage with
roof lining and side panals etc in vehicle.

its not that hard to paint a cage in the car, all its takes is prep and masking the rest of car off, the ease of painting it shouldnt be the deciding factor on a major safety item as this

NO argument that a proper welded in custom cage is superior to bolt on variety. But if a bolt on version has proper reinforcement plates at the mounting points then it is perfectly good. Certainly safer than running without a cage.

As mentioned nothing wrong with a properly fitted bolt in cage. Too many people just bolt them to the floor which is useless in the event of a accident.

This is a FIA National spec bolt in cage, goes through the dash though so gives you plenty of legroom to get in and out of the car, the cage was supplied in tube form from Rollcentre up the road from me.

I know a lot of people who think they can teach themselves to weld whilst fitting a cage, my advice would be don't bother when it comes down to something that involves your own safety. Same goes with seat bars, they may seem like a straight forward thing to fit but just think of the force going through them IF you have a big accident.

These are the feet you should use, even a weld in multipoint requires these



Rears need to either be boxed or sat on plates like so



Seats bars should not be welded directly to sills, again these should be plated




Not sure what James is waffling on about above tbh, any approved cage will help massively in a accident on a circuit, the issue is that when your on the road you won't be wearing a helmet and understandably thats the thing you need to be aware of as your heads not that strong.

Approved padding should really always be fitted to a cage, I even think its in the blue book now for race cars so you have no choice in the matter.

Well said

you really should always wear a helmet driving a car with a full cage, even approved padding with not prevent your skull popping like a grape in a big impact!
IMHO seeing as fitting any approved cage requires welding the appropriate reinforcement ot the chassis at the mounting points anyway, you may as well go for a full weld-in it is stronger.

Yes James i was referring to people that bolt them to the floor like the Audi bolt in jobs i have seen. Not like the pictures you have posted up. There Just as good as a welded in item "if" there done like you have pictured.

But if your going to go to that much trouble why not just weld it in and be done with it?

Also i quite agree, theres noting like smacking your head on a bar! and it makes any work on the car 100x harder

Your not going to drive round on the street with a helmet on though are you ? thats simply why insurance companies hate roll cages. In the case of the Corsa in the pics its what the customer specified he wanted as that pulls the shell together enough and doesn't add too much weight, were not taking it rallying or anything.

A full multipoint cage in a car used on the road is a nightmare, its like being 6 1/2 foot and trying to get into a Lotus Elise, very uncool and uncomfortable.

Amen

Depends if you're the Stig or not I suppose?

Yeah I would say a cage in a car thay sees the road is a compromise too far.

If the area is plated properly its still not such a issue but as you say its the people without experience that fit them that give them such a bad name.

2 reasons why that Corsa one is a bolt in, one its being powder coated and 2 the car will get sold on eventually and as its a Vauxhall that means the shell is worthless so it will get broken for spares to see the money back from it.

If you fit a weld in cage you have to paint the whole interior, if you fit a bolt in you can touch a few areas up, that I guess for some people is a good enough reason to not always use weld in cages.
