carbon carbon everywhere

I have a feeling one rim is worth more than my entire car though.

Well, that ought to reduce unsprung weight.

HMmmm...them are pritty...

rice.

those are so sick...how amazing would those be on a new z06 vette?

I have a good reason why I wouldnt purcahse anything carbon especially for wheels!!! Metals, even cast iron will have a bit of flexability. You hit a pot hole that is going to destroy your wheel. Its going to bend out of shape, possibly crack. Its not going to fly off and leave your car with a 15deg tilt to one side at 70 miles an hour. With a carbon fiber wheel, Its going to. You have to also consider the lateral forces. Carbon fiber wheels are directional in strength. Where you can be able to withstand 5000lbs one direction, thats not going to be true of the opposite without adding bulk and weight to the rim thus negating its benifits. Not to mention carbon fibers and expoxy resins have a life span of about 5 years in a typical UV inviroment, much worse if the vehichle is stored out doors. Anyone who works with experimental aircraft knows this and its usually the reason that they paint the planes.

I'm not an expert at this!I've only read a few articles about them. My g/f is in chemistry field and works with epoxy resins and carbon fiber structures alot, But she works with more benign things like Ibeams when it comes to carbon fiber. Their performance is purely situational. If you're going to be driving your car on a smooth even surface in a straight line all the time carbon fiber is for you. In reality, especially in the cold of minnesota!!! carbon fiber rims are plain and simple not safe. Now, if you're rich who cares? You can buy a new car every other day!!!!!!!! I've gotta ask those people though, how many new bodies can you buy?

I have to bring this up again, but carbon fibers strenths are purely diretional. Even if they have lateral,diagonal and verticle fibers strung out at the 0 45 90 degree marks you still have to worry about forces acting from the 1-44 46-89 arcs. You cant compensate for that angle of force with carbon fiber structures. Metals are strenthened through out.

I dunno, couple paragrahpes copied from a magazine article.. I just wouldnt buy them because they're expensive and alloy wheels look better.

they have passed every D.O.T. test including
(a) Radial Fatigue Standard test is 2.5 million cycles ours passed 5 million
(b) Cornering Fatigue 1.2 million cycles
(c) Radial impact testing this is the one that everyone worries about.. our wheel exceeded the imapct test by 60KG which has never been done before.
(d) was a repeat of A, B, C with low profile tire... this test not required by JWL or BSAU
(e) additional impact on unsupported inner flange without tire ( no wheel has ever passed this before our wheel)
(f) CASS test enviormental chamber designed to add age to the wheel
(g) repaet A, B, C on wheel post CASS test

after all testing the wheel was pressure tested to assure no micro cracks

This wheel compared to the Z06 wheel was twice as strong and held up better in impact testing then the Z06 wheels and we did it without the center spokes we also did all the same testing once again with only 1 support bolt in each spoke rather then the normal 2
People should realize how strong carbon fiber is... look at all the aircraft using this stuff.... unlike Alum this does not have a memory if you bend alum one time it looses more then half of its strenght..... I guess what I am saying after we tested these wheels, I do not like driving on any other wheels.

I just orderd a set for the SRT...

I dunno, the guy gets a little shady when it comes to talking about weave, molding technique chemical compositions cure times ect..ect..ect.. He's claiming that his rim is the first to pass a few tests as well. It could be true but when it comes to the physics of the matter carbon fiber is always at a disadvantage. Also I'd like to see this guys PHD..

Even if everything else is true about them being strong, I am sure that UV would kill the rims over a few years. UV ruins almost anything synthetic.
