You can gut the M5 strut assembly and install the strut insert of your choice, but the original factory unit is all one piece for the front of the car.
The rears are a SLS hydraulic type system and are driven by the two stage power steering pump through accumulators and have special springs that won't work with regular shocks.
Hope this helps to answer your question.
