What about the QA1 CF drive shaft, how does it compare to the stock--would it be better to just upgrade the carrier bearing or go to the CF shaft?
I think a Redeye driveshaft with the JBX carrier bearing would be a good choice down to a 9.5 second range.
Lower 9's and south of that, carbon fiber drive shafts have had their issues, seems like they all break sooner
or later. Chris Kelly (Kelly's Garage youtube) is on about CF number 4 on his way to the 8.8 range in his 2019
Challenger Redeye. The Mark Williams Enterprises two-piece factory style driveshaft is the highest quality,
strongest, and most expensive Hellcat drive shaft out there that I'm aware of. I guess if you are working your way
down in 60 foots and ET's you might as well skip the CF's and aluminum shafts and go big with the Williams
driveshaft it will more than likely work out cheaper in the long run.
