I upgraded to MPP Sports coilovers and am selling the stock late '21 m3p suspension (swapped at 43k miles, not including tophats which can be reused from your original suspension). I found this suspension to be more comfortable than my MPP coilovers at 43k miles, but less sporty. There we some major improvements by the time the late '21 M3P came out and this suspension feels much, much better than the earlier years.
