Can't say for sure for RotaxSpec. But Simonini says their version of the "C" is good for 150hp FE8E3F95-D5AA-40B1-AE15-4577DB284D6C.png

Will you be using the clutch coupling, or the Hardy Disk coupling? C boxes have been mated to BMW boxers in the past.
will be using the rubber doughnut coupling, clutch coupling came out on E gearbox the one with ther starter motor, would love got own one if can
