Great thread thanks!

 

Its nice of Jarrod to post this, but i wouldnt depend on a thread like this for this topic. If any of you are considering getting a cage, go directly to the sanctioning bodies CCR/GCR for the rules. If you guys want a thread to have a discussion, thats a different story. But if you want the rules...go directly to the source, dont rely on any thread. Also keep in mind, some classes have class specific rules for building a cage.

 

I'm posting the rules directly as written in the rule books. Of course they change a bit each year so the most current book/update should be the final reference in case this thread is not kept up to date. That is the purpose of this thread, though, so when any changes arise they should be noted in this thread by me or others. . .

Perhaps I should post a link to the GCR/CCG from which each rule comes. I will update the above posts with that info. . .

 

Its really nice of you to want to undertake this responsibility. If you want to do all this, heres what id suggest. Dont just post the links to the rules, post the links to where you got them from. But if someones a NASA/SCCA member, they should already know where to find all the rules. So in a sense, posting this info is only going to help people who are completely new to all this. Id also stress in your original post that people should always go to the sources directly. And remember, some classes have class-specific rules for cages.

 

Thanks Ed, I will do that. Great advice! It's still a work in progress and I'll update the first few posts with more info/links in the near future.

 

Good point, nothing worse then building a car to a specific set of rules, then finding out it has to be done all over again. With a cage that would be a real pita!

I think the warning to check the links for any updates since the post is always a good CYA move.

 

Here is a link to a bunch of cage build pictures for my SCCA T2 EvoX:

The rules for SCCA Club Road Racing can be found here:

Download the most recent rulebook, which is updated monthly and go to the applicable section for your class. General Cage rules can be found in Section 9.4

 

In looking at a lot of interior pics of caged Evos, it looks like a majority are NOT cutting the doors and doing the Nascar ladder-style bars. Why? I know this is an added cost, but it is that or just because the extra interior room just isn't needed?

 

It is a complicated job designing the cage to accept door bars around or through the B pillar. I have a NASCAR impax foam door piece but have not installed yet. NASCAR uses sheet metal to cover it but we were thinking of bonding it with fiberglass or carbon fiber onto my Seibon door.

 

My guy didn't have any real problems with it, I personally don't like having a vertical bar like that in the way of "escaping"

 

CJ! Where you been man Start a thread already on the....brand new...car

 

I like the job. A little more weight out there but welded to the pillar and braced.

 

All of the newer rally cages require that bar because it does a really good job of keeping the windshield area from collapsing in during a roll-over event. Not as high of a concern for a road race type car I'd guess though.

The rally guys don't like bowed-out door bars as much because if they take a big hit, they can just bend all that slack inwards towards the passenger. By having the bars short, any forces put against them is instantly vectored out to the main hoop part of the cage which further reduces the chance that they'll bend inwards.

Also wondering - is there really a benefit of having the nascar door bars if your torso won't be near the part that's bowed outwards? Seems to me a good hit on something like that would try to push the bar close to your seat inwards sooner than a car with a traditional door X.

I always find it interesting to see different designs though.

it is harder to get out , but a same time supposidly much safer.

I mean it is actually harder to get out obviously but for rally you need this bar , other wise you will not pass inspaction.


this is a fairly proper rally Evo X cage

 

For rally for sure I'd have it there...and a deployable parachute or two. Should be in the rally rule book
