:Most carbon fiber driveshaft manufacturers use adhesive to secure the yoke to the carbon fiber tube. High loads can cause the adhesive to fail, causing the yoke to spin inside the carbon fiber tube. Kuah had issues with this on his race car. :From their site: :[ HREF="http://www.bactechnologies.com/shafts.htm">http://www.bactec hnologies.com/shafts.htm ] : :"Carbon Fiber Driveshafts :BAC's U.S. Patented design is a mechanically integrated one-piece design where the aluminum yokes are filament wound into the shaft. Wet composite material sinks into knurling on each yoke and encapsulates it during the manufacturing process. Therefore, each yoke is permanently locked into the shaft when the epoxy composite is cured. This revolutionary design does not rely on adhesives to transfer the torsional load from the aluminum yoke to the carbon fiber composite. Independent laboratory tests have revealed BAC's Carbon Fiber Driveshaft has significantly higher torsional strength and less weight over popular aluminum shafts and all other carbon composite driveshafts." : :I'd like to have a CF driveshaft for the NVH reduction, but didn't want to deal with the slippage issue that Kuah encountered. This may be the answer. I don't know how much they cost, but do know they are a lot more expensive than a std CF DS. I emailed them for a quote.
