@panterapatt posted:The GT40 ball bearing is tapped into the crank end. I dont have either yet so can not comment on how it works but there are hundreds of SAFIR clutch setups in use so I am going with their engineering that has been done on this system with the ZF 17mm spigot in that bearing. I know of several cars being built presently using this.
I wasn't commenting on what SAFIR recommends. They know much more then I do.
