I added full front M3 pieces and the ball joint / bushings (I assume) are definitely harsh over sharp bumps such as RR tracks or metal-jacketed expansion strips. Love the steering - but beware. My car is a DD with zero track time so I don't think I made the best choice. I will avoid the M3 front arms on my 2013 (on order). The M3 rear subframe bushings are a definite plus with little NVH penalty.
