Doe's the six point always make a dent in the passenger side dash..?

 

depends were you bolt that bar down, most people want more leg room which means the bar will end up pressing against the dash....these cages are intended for RHD :/



taken ~month ago.

 

 

I had a questions about the cusco roll cage, does it come assembled? And since it's in parts does it make a weak structure and easier to bend and break because it's not one piece?

Just looking at this picture, made me question the quality of the roll cage and not being all in one piece does it make it a weaker cage and easier to break and bend on impact?



Thx

 

aDog, i think its strong enough

 

its not legal in a lot of racing bodies. so take that as you will... I personally went with a hard dog

 

(except I had a 6 pt bar custom built.)

 

It's not legal in a lot of race sanctions only because it's not FIA certified. Not for any other reason. Even though inspection holes are present in both the Spoon and Cusco models, no one ever takes the time to inspect and certify the bar.

Unfortunately Japanese manufactures and even some Japanese sanctions are not concerned with FIA approval.

Because of this, I've written to OPAK regarding getting documentation from Spoon that the roll bar will withstand a roll over when properly installed.

NASA has already advised me that they will allow me to race using this bar as long as I present documentation that it is a safety bar and not just for aesthetics.

I am not sure if there is much difference from the Cusco chromoly to the Spoon steel, but personally I feel confident that if I should roll over that the bar will do its duty.

 

not necessarily true. If you look at bodieslike NASA, their rules revolve around number/location of bends as well as thickness.


Although NASA is super incosistent. It seems to depend on region. I have had them let me run with no bar once, and then one time I had them ask me about the broomstick rule.

Of course as you mentioned the first thing is tube thickness. I continuously hear mention of the bend rules on the main hoop, which I am assuming comes from the cage rules (below from the CCR). and especially when you get into TT this seems to be the part of the safety CCR they follow

15.6.6 Main Hoop
The main roll cage hoop should be as wide as the full width of the interior and must be
as close to the roof as possible without violating CCR section #15.6.20 Inspection. One
continuous length of roll bar tubing shall be used as the main hoop. The main hoop
must consist of not more than four (4) bends maximum, totaling one hundred eighty
(180) degrees +/- ten (10) degrees.
15.6.7 Diagonal Brace
One (1) diagonal brace shall be used in the same plane as the main hoop. The diagonal
should be one continuous path; meaning that it must conform to Diagrams 15.6.7a or
15.6.7b. Note- If the installation method from Diagram 15.6.7b is used, the builder
should pay close attention to alignment. One end of the diagonal brace shall attach to
60
the corner, or horizontal part, of the main hoop above the driver’s head, within twelve
(12) inches of the driver’s-side corner. The other end of the diagonal brace shall attach
to the mounting plate (or to the main hoop as close to the mounting plate as practically
possible) diagonally opposed to the driver’s head (passenger floor).
15.6.8
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 bulkhead(s) provided the
bulkhead(s) is sealed around the cage braces. *There may be certain exceptions
allowed for cars that cannot possible meet this “no bend” requirement. One exception is
listed [Ref15.6.11.A)]. Other exceptions may be made (not guaranteed) if all of the
required bars meet the specifications for a vehicle in the next heavier weight
classification and the alternative design is submitted to the NASA National Office for
special allowance.

 

Except for the diagonal bar, the Spoon bar meets all these specs.
