If anyone thinks that the drive torque can be transfered only by the clamping force against the hub then I say remove them, use 1/2" diameter counter sink machine screws to hold the hold the adapter to the axle flange and save the weight! If it could be done, the F-1 guys would have devised a way to do it long ago. The studs, pins, or sleeve nuts are in shear and transfer the twisting torque to the wheels. The first 289's had splined adapters the splines ultimately were deemed insufficient when HP and torque were increased and the studs were adapted from other racing fitaments. You couldn't clamp the wheels tight enough otherwise. Any takers?
