Default Roll cage materials SCCA

I recently went to a track day at Sebring, and as passing through some very strict tech, they told me that my cage wasn't the right materials. Does any one have a list of tensiles, and it wasn't PVC from home depot,

ERW or DOM is all they allow and after December of 2002 they will not certify any new ERW cages - only DOM.

In terms of the specifics regarding thickness, ID/OD etc. you will need to look in the GCR.

vehicle race weight wall thickness and diameter
under 2000 lbs 1.50x .120
2001-3500 lbs 1.75x .120
over 3500 lbs 2.00x .120

This is for all (DOM and ERW mild steel constuction) roll bars and cages built up to 12/31/2002.

From what I understand, the ERW will no longer be allowed for new cage construction after 01/01/03. I beleive by construction they mean, certified and stamped. I also read a diagnonal brace must be installed (welded or bolted) on EVERY 4 point bar registered after 01/01/03.

Not always. Most clubs only require roll protection in convertibles (for lapping days). Check with the club to be sure.

Many clubs use the SCCA GCR for their rollcage specs. But you still need to check for subtle differences.

Remember that "new" or "old" is defined in terms of when the SCCA logbook was issued. If you have an ERW cage that has been in a car for five years but has never had a logbook issued, it won't be grandfathered in (most likely). Without some more detail, it is hard to really answer the original question, however...

I would think your roll bar is erw as this is what most of their cages are currently made from.

Yeah, question has been answered. I looked at the IO Port page (I got the bar through them) and based on pricing, I'm sure I went with the cheaper option.

Anyone know if my ERW bar will be legal for the THSCC time Trial series next year, or do I need to get it teched before October and start a log book with the CMP event...

if i remember right, ERW storts out as a flat piece and is rolled and seam welded, DOM is extruded directly into a tube form, i believe

the events that i will be runign or might be running would probally include scca solo2, porshe club track events, and say scca track events?

I have a civic hatch with a b18b swap. what will i need starting next season?

I just had a cage done in the past two or 3 minths by Kirk. They issued a Roll Cage Certification and on it it lists the material (DOM) diameter and wall thickness of the tubing.

Obviously they are ahead of the curve and are using the DOM material. I am happy with the cage and would recommend Kirk to anyone.

The SCCA Pro Racing Regulations website has the rules in online .pdf
The links arent working right now. =P
I printed it out tho and it says for under 2000 lbs 1.50 x .095 wall thickness and diameter (alloy).
Can anyone verify if this is correct for me?

Thank you.

As of January 2003 the only materials allowed will be DOM and ChromeMoly tubing. ERW is no longer permitted. Take a look a the current issue of FastTrack and the pages in the GCR concerning cage specs for the rest of what is to be in your car.
If you are attending a NON SCCA track day event it is quite possible to NOT have to install any type of roll cage/bar assembly. Most of us have updated the seabelts in some way while others have put in special cross bars for the shoulder harness. Then there are those with SCCA cages. My Prelude routinely runs at Pocono and The Glen without a cage with PDA. The CRX is prepped for Improved Touring and has a full 8 point cage in it. The cage was designed and built by KIRK-really nice work and it welded in perfectly.
Do not be unwilling to go and run at a reasonable speed during a "school" event. Many of my fellow track day driver friends have very streetable cars that they like to play with on weekends. Race events are a very different thing and I will urge that you consider the safest cage that you can get into your car.

Default Re: Roll cage materials SCCA (jc836)

just going thru the october fastrack, and there is a couple pages dedicated to performance rally. in the fifth article, it describes a suitable rollcage and its parts. it describes the Rear Bars "must attach to the Main Hoop as close to the upper bends as possible,... and not closer to each other than where the roof bars attach to the main hoop". Having seen Kirk Racings cage for the CRX, their cage would be totally unacceptable as the rear bars mount towards the center of the top of the main hoop like 6" apart, and NOT far to the sides. Now, this is the wording for Rallying, but I imagine the same concept should be applied to the ITCS rules when building a cage, even if it isnt spelled out. For that reason, I dont have much faith in a Kirk cage, and to be honest it bothered me when I first saw it, unles of course they change the design, which im sure they can if needed.

So I assume that it is best to have the cage custom made. At least 6 point. DOM materials, as an Integra 1.75" Chromoly. If so I was quoted at 300 dollors. If anyone else has a better offer let me know. Also i noticed that someone posted that they had harnesses but not a roll cage. I find this very dangerous, "as if you role the vehicle, and the roof crushes in, you will not be able to be pushed forward, the harness would keep you upright postion with the roof forcing on your head." I got this from the SCCA web page.

Don't go to the effort/expense of CrMo tube. There are several types of mild steel DOM tubing that work great. I am surprised that SCCA actually took a position on the rollcage/harness issue. Having said that, I don't know that I have ever heard of an SCCA region doing "high performance" driving events that weren't actual club racing schools - I'm not surprised that they exist, I have just never seen one first-hand.

So what companies would you guys reccommend for a roll cage. I am planning to start autocross sometime soon. And would like to have the right specs and would also like to get the best deal and quality or whatever would just be best. I drive a 97' Integra with few mods to the motor and NO suspension work at this time. Of course my suspension will be finished by the time I start, but would like to get the roll cage in before. Please give me links or contacts if you guys have any.By the way i live in northern Virginia and would be going to summitt point raceway, just incase some of you are familiar with their rules and regulations. Thanx!!

RockDawg - i just had a roll bar custom built/installed by Kearney Racing in Landover, Md. They took about a week and a half to build it and its a very nice peice. IM me if you'd like their phone #, directions to the shop, or if you'd like to check out the work they did for me.
