i have a 4 pt schroth camlock harness. 3 inch shoulder, 2 inch waist with anit-sub tech. holds you in great and performs flawless. obviously if i ever went serious racing it would be a 6 pt and full weld in cage, but time, funds, and driving limits that.

 

The schroth 4 point harness with asm works good and safe. But I think NJMP have a new rule this year that does not allow 4 point harness even if it's DOT legal.

 

My basis for my comments are based on internet rumors and not something I have directly experienced or verified with official sources....so if you really want to know, do some more digging to verify this...

Apparently NASA started the no 4pt belts (including Schroth ASM) trend. I disagree with their call to ban Schroth ASM belts - I'd take schroth ASM over stock 3pt any day (assuming proper installation was followed which includes seat compatibility check):

NJMP however is apparently strict about checking the belt dates:

that would be really stupid. Everything is DOT legal should work perfectly on stock unmodified area's. There is many extended test has to be done before you get DOT approval. Denying that....
If they do have anti DOT rules , that is just plane ignorance. From there everything ion the are DOT approved, can be denied with a same principal on track as an unsafe equipment on standard car. How dumb is that? LOL
That would be a really bad ruling and really unnecessary bureaucracy. They maybe doing but that only would prove those people who did that , the absolute incompetency from they side.

ps: i'll know about this more since i will have a testing in NJMP in this weekend saturday - sunday all day.

 

Custom Cages kits are great (i have one), but you have to make sure they're legal for your series (should you decide to up your budget). Rally cages and road race cages are designed to protect from different types of accidents.

here you go, built by AMS

 

Rob, Dont forget a full face helmet at NJMP. They do not allow open face helmets. (racing only tho). I believe the PDX was granted a waiver.

QUOTE FROM NEW JERSEY CHAPTER #62 MAY 2009 to FEB 2012

§ 13:62-3.6 Helmets and eye protection
(a) All drivers shall wear a properly secured, full face
helmet, with face shield, which meets or exceeds Snell
Memorial Foundation Testing Standards M or SA, incorporated
by reference herein, as may be amended and supplemented,
which has not reached the expiration date established by the
Snell Memorial Foundation at the time of the event. The
standards are available from the Snell Memorial Foundation,
3628 Madison Avenue, Suite 11, North Highlands, CA 95660.
A Nomex, or similar fire-resistant head sock is recommended to
be worn in conjunction with the use of the full face helmet with
shield. The use of open face helmets and goggles shall be
prohibited.
(b) "M" (Motorcycle) Snell rated helmets may be used in
all motorcycle events and automobile events where fire ratings
are not required.
(c) "SA" (Auto Special Application) Snell fire-rated
helmets shall be used in all other applications.
(d) Helmets shall not be required under certain instructional
and guided tour events where the maximum speed on the track
shall not exceed 55 miles per hour.
(e) All helmets used by riders on motorcycles and open air
race cars shall be full-faced and shall be worn with the visor in
the closed position while on the track, the above rating and
standards not withstanding.
(f) (Reserved)

 

NJ law also doesn't have allowances to use helmets based on other certifications which are commonly allowed by sanctioning bodies. For example, Stilo and Peltor helmets often carry the British standard, so lots of rally guys had to buy new helmets to run the RallyCross at NJMP last fall.

Requiring full face helmets in a car with a windshield is dumb. I've also heard stories where people got injured when the airbag went off and caught the chin part of the helmet.

The biggest difference you will find (after doing much research into building an all around cage) is the tubing diameter of door bars, cross bars in the main hoop and back stay bars. Rally america rules allow smaller( lighter bars) in these area's. But on the other hand a SCCA cage dosn't require door sill bars that are the same diameter as the main hoop. So thats one door out of 2 required. Also, the extra A pillar support bar is required in rally america. So, in theory a Rally america cage with and X door bar has 3 door bars and you could argue that the A pillar support is a 4th. So IMO i can't imagine how a Rally america cage has less side impact protection then a road race cage.

Thats the jist of it (not all of it but close) . If you go with 1.75x.095 or higher in all required parts you are good. or you can use a mix of 1.75x .095 and 1.50x1.20 for any required bars. That should about do it for a universal Rally, hillclimb, Road racing cage.

 

All good points, but I think you missed the biggest one - if you use a FIA homologated prefab T45 chromoly cage, the wall thickness is something like 0.067 for the larger tubes and 0.047 for the smaller ones. The diameters are something metric that's close to 1.75 and 1.50 but I don't remember if they're bigger or smaller.

Strength wise the Custom Cages homologate cages meet the FIA tests (i.e. it's still meeting the crash regulations that a 0.095 DOM tube), but the road race guys might freak if they drilled a hole and measured bar thickness.

THANKS GUYS!!!!
I was bringing my Peltor down... It is funny ...whats up with those guys down there...
I mean the WRC cars and all FIA rally recommends and runs these helmets and they are the best on the world , but in NJ on NJMP some how they dont qualify.... I start feeling i go somewhere i'm not ready yet LOL

 

Wait to you see the blank stares you get from some tech guys! Not all but some.

I have acutally looked for FIA tech specs on their site but couldn't actually find anything very easily.

 

the problem with the US motor-sport, everybody wants to rule it, and they try to dream up different rules for a same racing... How dumb is that? Its like you build a rally car and you have to modify it if you run a different rally...
There is a reason why the WHOLE world except us runs FIA rules...

And the real pathetic thing is, they rally hill climb etc is not even close for those who used - tested those rules. But no, the US clubs has to do it "better"...
And they wonder why they killing the sport actually.
Those people doesnt belong there. The motorsport never be safe . The reason is, when you get to the point when it becomes safe ; no one cares anymore.... sound familiar? LOL

Motorsport = danger. That is why we love it. other wise we would all play chess. With a mandatory heart -attack pills on the table.

Rob


ps:
damn i have to dig up my go-kart helmet My friend will bring down 3 racing go kart by the way, the same weekend.... so i will be on and off

 

I know. Sometimes i feel those tech guys actually a same guys who's lunch used to taken away in kinder-garden by others, and they back from the past for a revenge....

which rules are you looking for?

 

Welcome to the US! It makes no sense to me also.

I was looking for FIA cage specs just so i could do more research into cages. I have had many people question as to "WHY" i used bent door bars to form the X instead of one bar bisecting the other to form the X. I then questioned this myself and found that FIA has just done research into why the Bisecting bars are not as safe. I was just looking to see what else i could find that people "think" vs fact.

Its mind blowing reading thru cage rules from every group under the sun.
