Is it legal to have a 10pt(NHRA spec.) in SM. My car is a dual duty car, I use it for drag and autocross. When I read the 2006 rule it said that it could be bolted in.

 

what would happen if I was to place the car in SM and the cage would not be legal. Would I have to pay a fine or anything?

Also everything that I read about the class above SM said that is had to be NA unless factory FI.

 

You should probably post a design as well as what materal is being used. isn't the NHRA cage the wrong design? if the cage isn't legal you will probably not race.

edit through you were talking about HPDE and RR my bad

by SM you mean SCCA Solo II street mod class?

i thought that they took the rules out on roll cages. i think in 2005 it used to be something like 4 point welded, or 6 point bolted in. last time i went thru the rules i couldn't find anything in their on roll cages.
i seriously don't think anyone would say anything either way. if anythign it's a disadvantage because of that extra weight (not to mention the weight it adds up high) though if your interior is stripped out or your door panels all cut up because of the cage then that would be an issue.
not a whole lot of people run cages in SM, at least in the WDCR region.

 

Would that put him in a Prepared class, rather than Modified?

Added weight is a disadvantage, but using a cage to increase chassis regidity is a definate advantage. Are the 07 rules out yet?

 

As I said in my first post my car is a drag / across car. And I was getting close to the 11.49 mark with my car, so I have start to save for the cage.

The cage will look something like this, no strut top connecting or anything.


I only do autocrossing for fun, I just do want to pay any fines or anything for having a cage.

 

You won't have to pay fines, you'd just be reclassed. Ask the coordinators where they want you classed to avoid complications.

That's correct, if you're turbo you're SOL in terms of getting classed competitively. I'm not sure you can get a N/A FWD honda that's SM-legal into the 11's anyway, so yeah I guess you're turbo

 

Yes the car is turbo.

I do not really care if I am competitive. As long as I am not turned away from racing, for not having a class to run.

Thanks for your help

 

oo youll have a class to run...

.. just race in a prepared class
or you can see if ur region does FUN runs where you are not interfering with other peoples points but still gettign timed

 

8pt welded-in cages are allowed in SM via SP rule section 15.2.I:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">I. Roll bars must comply with Section 13.2.G in Stock category.
Roll cages must comply with the following:
1. The roll cage need not be removable. It shall be bolted or
welded to the car.
2. The cage shall attach to the car at no more than 8 points,
consisting of the basic cage with 6 attachment points, and 2
additional optional braces.
3. The forward part of the cage shall be mounted to the floor of
the vehicle. If used, the 2 optional braces referred to in (2)
shall be mounted, one on either side, from the forward section
of the cage to the firewall or front fender wells. No
braces shall pass through the front firewall.
Installation of roll cages in Street Prepared cars must follow
the same standards for interior modifications to accommodate
the cage installation as those which are applicable to Showroom
Stock cars in Club Racing.</TD></TR></TABLE>

That allows a decently serious road racing cage. Also... Turbos are allowed in SM as well, ie unlimited drivetrain and same mfg swaps. You can swap in a blown K24 if you'd like. They will even allow relocating and welding new motor mounts for next year.

PS: where are the points in an NHRA 10pt cage?

 

ok, quick search found this:



NHRA seems to call this a 10pt for some reason. This would be considered an 8pt by SCCA rules. 4 points on the main hoop (?!), 2 on the rear shock towers and 2 in the front. The problem would be the 2 extra points on the main hoop. The rule quoted above states that:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">If used, the 2 optional braces referred to in (2)
shall be mounted, one on either side, from the forward section
of the cage to the firewall or front fender wells.</TD></TR></TABLE>

Edit: ok, i see. If i extrapolate from what is called an NHRA "8pt", it would seem they count the front top section (2 corners of windshield) as 2 points even though it's not welded to the chassis...

 

the two rear post do not go to the sturt ower they go passed there(or at least on the one I was going to have built) to about here the kirk bolt in cage has them, but that is what the cage will look like.

 

Why dont you check if the NHRA rules would accept an SCCA 8pt cage (=10pt) instead and build that? Save yourself the trouble of redoing it if you ever wanted to do hpde/time trials and maybe even road-racing later on?

 

Yeah, ok, but what kind of tubing is it? Keep reading your rulebooks, guys.......good luck
