Pretty interesting.. but there has to be some downside to them. Or, every F1 team would have carbon fiber wheels.

Rules to keep costs down is all thats going on in F1 these days.

This has probably been around.

And you know what about CF? :rolleyes:


It passed all of the D.O.T. testing if you didn't care to read farther down in the post.


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

They were listed as $1,500 per wheel in the Popular Hot Rodding coverage, and a link was given to their... non-existent... web site. :)

Wow.....well, they are half the weight, so twice the cost, huh? :D

I've seen at least a few Formula SAE cars running carbon fiber wheels over the years. Someone mentioned one of the teams that had them in that thread.

The local University of Texas at Arlington team headed by Dr. Bob Woods built some carbon fiber wheels with aluminum centers a year or so ago. They have their own autoclave and are making things like wings and even a complete undertray for one of their cars that hangs from the suspension uprights. Very trick.
