Working on a new project currently. Its for a local Vette owner and his line of car, but it can be carried on over to our cars as well. In house testing being done currently...I think it will stand the test of time quite nicely.
Not bad for .081" (2.06mm) +/- .005" thick carbon fiber with a tensile strength of 64,000 PSI. I figure there it a little more than 800 lbs. sitting on it, full weight of the car on it, and the tube isn't even turning oval.
More than good enough for what its going to be used for.
