I have two questions...
1. I noticed in the undercarriage shot you use of the ds installed there doesn't seem to be a ds loop. A ds loop is a safety reqirement at my local strip, Mission Raceway, and at most strips for cars running aftermarket shafts. Also from a safety point a loop helps to prevent the shaft from entering the passenger compartment in the event of a ds failure.
This is the reason our cars have two shafts, with rear seats in our cars there were concerns during design with a one-piece shaft and what could happen if it failed, two smaller length shafts are less likely to enter the passenger compartment if they suffer a failure.
2a. Were these Independantly tested to failure by a Lab that performs such testing and if so what were the results? If not, why?

1.A driveshaft loop is not installed in the picture since it is not required. Some drag strips require them for cars that are capable of running under a certain time, which in our area is 10's. Considering there are very few Gs that are capable of running 10's we do not include a loop, however we may offer one in the future since I will likely need one for my personal G.
Having a back seat has absolutely nothing to do with a car having a 2pc driveshaft. A 2 piece shaft is just as capable of penetrating the tunnel as a 1 piece. Manufacturers have much higher priorities than just performance in most applications, like cost. This is obvious due to the G35 not receiving the CF 1 piece driveshaft like the 350Z, neither of which likely received a aluminum shaft due to the potential for some resonant noise as some have mentioned with our shaft.
These shafts, along with our Z32 driveshafts have not only been lab tested but tested on our in house dyno and in our personal street cars for thousands of miles, one of which being my 600+rwhp G35.
They have been lab tested to hold right at 5,000 Ft-lb, which would require ~1100 rwtq through the G35's 3.794:1 1st gear to produce, And also dyno tested to 188mph

Unfortunately I have not been very available on the forums the past few weeks, but to update.
We didn't receive as many shafts as expected, and the few we did receive were pre-sold. At the moment we are unsure when we will be receiving more, however when that does occur it will be a much larger quantity to fill the demand.
I apologize for the inconvenience

Thanks for your answers, please add me to the list for the next batch. At my local track a ds loop is needed on any car running slicks no matter the et and on cars running quicker than 11.49. Cars running 11.49 or slower on street tires don't need one. Just a thought...an addendum under your ad advising customers to consult track rules if they plan on racing their car so nobody gets surprised when they find out they can't race without a loop. Or...well...you already know.
