I thought someone on here mentioned recently that X bars behind the main hoop in a rollcage are illegal for Honda Challenge. Is this the case? Hope not otherwise we'll be doing more work to the Prelude cage.

I did a search, looked around this forum and checked the NASA site, but didn't find an answer.

 

the "X" is legal IF you have the "l l"

the "l l" must not have more than a 15 degree variance from being perpendicular to the horizontal line of the main hoop/halo ... i'm sure i didnt word it as the most understandable... but it shouldnt look like "/ \" or "\ /" more than 15 degrees.... from "l l"

 

The cage doesn't have any "l l" yet. if those are added the angle will be about 30 degrees so we would be fine.

Now if somebody were to offer us $13,000 for the car we could forego all this...

 

ummm... you can only varry +/- 15 degrees from 90... SO if you look at the main hoop as "----" that is 0.... "TT" being the perfect 90.... you can only go "/ \" to 75 degrees from the 0. this is all looking at it standing in the back of the car...

someone post some pics please... :-P i just inspect the damn things i dont have it in my own car... and i am at work with NO pics to show as examples.

 

Oooops. My bad. Read your post incorrectly. Looks like the bars will need to be removed.

 

Bob,
The 'X' doesn't need to be removed. You just have to add the 'regular' rear stays.

From the 2005 CCR:

15.6.11 Rear Braces
The main hoop must have two (2) braces extending to the rear. The braces shall be
attached as near as possible to the top of the main hoop, and no more than six (6)
inches below the top. The braces must not contain any bends. There must be at
least 30 degrees between the plane of the main hoop and the plane of the rear braces. The main hoop rear braces shall be installed to form no more than a one hundred five (105) degree angle or no less than a seventy-five (75) degree angle with the main hoop when viewed from the top. The main hoop braces may be mounted at the rear shock mounts or suspension pickup points (providing that the braces remain in compliance with all other sections of the CCR). They may go through any rear bulkheads provided the bulkhead is sealed around the cage braces.

 

Thanks everyone. Now I know what we need to do.

 

Here's a pic of a legal X.

 

thank you sir... thats what i needed him to see
