I was wondering if anyone knows what cage specifications I should follow in order for it to be accepted by SCCA? I'm using cromolly (hopefully that's how you spell it) for the custom cage, which plays a factor in the thickness measurements. I tried to do a search, but I couldn't find what I was looking for.

buy a gcr. has very specific info.

 

Yes, I ordered it today. However I think it takes a while for it to be delieved. Just wanted to know if someone could help me get an idea right now.

 

So, you're having a custom cage built by someone that doesn't know what he's doing, eh?

 

Good point.. Do your best to have a shop that is well versed and has a few cages already under his belt..

Its your life...

 

Well the guy who's building the cage is Mitch Piper, who is known to be highly skilled with this type of work. He just wants me to make sure that I find out the exact diameter/thickness level specs that will be accepted for my specific car (class/weight). Now because I'm new at all of this, I'm not sure if each car/car class has different requirements. Meaning is there a one set standard for all cars? (I hope I don't get flamed for this)

 

I've heard of Mitch.
Just wait till you get the GCR or call the SCCA.

Then again, someone here will probably have the min. OD dimension for you soon.

 

What class are you running? And what car?

For IT, SS, and T cars:

Under 1500lbs: 1.375x.095 DOM/seamless/alloy
1501-2200lbs: 1.5x.095 DOM/seamless/alloy or 1.5x.120 ERW
2201-3000lbs: 1.5x.120 DOM/seamless/alloy or 1.750x.120 ERW

For the rest of the specs (plate sizes, tube bends, etc) you'll need the GCR (too much to type out).

 

I was thinking of either running in Show room stock or honda challenge. The car is a 00 civic si, which should fall into the "1501-2200lbs: 1.5x.095 DOM/seamless/alloy or 1.5x.120 ERW" area.

 

HAHA!! I was going to actually reccomend him!

Good.. He will do a top notch job..

Now I need to fly him out here to do mine..

 

There are some subtle differences between the SCCA rules and the NASA rules on cages. Make sure of the rules before you proceed.

 

Are you sure you want to go with cr-mo? It is my understanding that cr-mo tubing will need to be heat treated after welding. Might be pretty tough in a car to do. Most people go with DOM.
added in edit: Check with other competitors. I don't think you will get the car under 2200 lbs.

You are right about the 2200lbs, I don't know what I was thinking. I should be in the 2201-3000lbs: 1.5x.120 DOM/seamless/alloy or 1.750x.120 ERW area. As for cromolly, I know of a couple of people using it. From what I was told cromolly is suppose to be lighter and stronger (if not the same strength) as DOM. I guess I'll check back with Mitch on that one. Also I think Mitch has a way of heat treating the cromolly, but again I'll have to ask him about it.

mich piper does excellent work. highly recommend him.

RJ - who's going to pay him a visit this week actually to find out costs for a rollbar in his saturn

 

Would you care to either post his contact info or IM me with it.
Thanks.
Ed -- who still doesn't know "exactly" what he wants to do with a turbo ITR.

 

call up http://www.gtpracing.com

They have a CNC bender and only use Chromoly. Tell them Greg B. sent you.

-Greg

 

Thanks, for the link!

I'll see what I want to do after the car's "renovation", and whether we can get it to pass the local inspections.

 

I believe Mitch's number is (703) 530 - 0353.

 

Thanks again!
I'll have to make some decisions, soon.

Anyone need a Kirk rollbar for an ITR?

Mitch put together my cage. Ask him about going chrome moly. He'll probably tell you to forget it, unless you're really hell bent on dropping an extra 20 lbs.

Oh, he won't like it, but tell him to paint the bars before they go in, but don't tell him that I told you to ask that

I wonder if he's available to do a cage on the West coast..


Chris -who thinks he is.. for enough money.

 

have any of you guys had a custom 4 point rollbar made? What were the specs and costs?

Thanks,

RJ

 

Warren: I think we met a while back at summit because I've seen you car before (maybe a year ago). Do you own a yellow S4? Anyways your cage looks awesome, is it the Motorola cup setup?

 

I used to own a yellow S4. Ahh, I miss that car.

Yeah, this is the setup that Mitch did for 2 Grand-Am cup cars.

I have a welded in custom 4 point. DOM 1.75 x .120, paid $400 installed and painted.
