It seems that there have been some issues with the housing hitting the floor of the car in some cases.

with the moser, the top most bolt that holds the cast torque arm mount to the housing hits the floor on lowered cars, makes a nice hole. Might be able to remidy this by replacing the large hex bolt with a round button head allen bolt

not sure about the currie, but honestly, their torque arm mount looks a bit flimsy.
