Maybe Bony will convince them to make a set for our FGTs.

There is another company by the name of Dymag that makes carbon fiber wheels (which we’ll cover in a future post), but their hub is made out of magnesium. Apparently this is for strength reasons, which makes me think these fully carbon fiber rims should only be used for show cars. I’d like to hear Weds Sport’s thoughts on this.

Damn!

I had heard of that happening on motorcycles running dymags before but never cars. That's a pretty scary sight.

Just from the standpoint of driving 'same on the streeet with no other "issues" considered, "curb rash" on one of these would ruin your day. (So would a rock chip... or chipS.) :willy

curious, the middle part of that wheel is aluminum right? did the failure occur on the positions where the aluminum spokes were bonded to the carbon fiber ring(wheel), or did the middle aluminum part just broke from the spokes? it doesnt look like any part of the cf is damaged, just the middle aluminum spokes

Currently questionable to permanently attach metal to cabon as in this wheel, altogether a different situation than an all carbon fiber wheel.

This is how the Dymag spokes are attached. From the picture it appears than the spokes failed near the hub. The GT3 doesn't have near the rear wheel torque of a FGT, but my guess (not factual) is it was a combination of forces and most likely the lateral loads cornering from the Hoosiers overloading the spokes.

Doesn't someone own a GTX1 with these wheels?

I would say that was perhaps from a tork flex caused from movement in the outer part of the wheel .

I heard carbon fiber designs don't lend themselves well to forces in all directions. They work best in a unidirectional application. It does not mean wheels could not be designed properly using carbon fiber. Just looking at the Dyna wheels I do not like the attachment points at all, I'm not surprised a failure occured with those. The solid carbon fiber wheel looks much safer but I would like to see a lot of successful testing before considering them.

This looks like a wrap job.. But there is a link to a future HRE CF barrel wheel...

Must be only CF the weight is extremely light.


...One wheel weighs in at just 2.76kg, which works out to be 6.08475844 pounds...

Clinton,
I think something was lost in translation or misinterpreted. 6 lbs or anything close to that does not sound realistic. Also CF at the Lug area is not realistic. The CF and resin will not take the stress of the lug torque. There is not a different hub material unless it is aluminum underneath the CF. This would lead me to believe it's a wrap job. Also those spokes would be difficult to make. Dymag and this new HRE wheel have metal hubs. Magnesium ( Dymag ) and Aluminum ( HRE & CEC ). Last year CEC showed a wheel at SEMA simular the HRE concept. The link is very interesting. I think that link on the same page to the HRE CF wheel is promising. Thanks for posting I had not seen the HRE version so it will be something to watch ..:thumbsup
