Tie rods/steering feels tight as it should be. Everything was tightened correctly at ride height. When going over some bumps I get the THUD noise/feeling as if the shocks are blown. The Koni's are on the softest setting. I do not see any visible leaking from the shocks though. I do feel as though the front is a little too soft but if I stiffen up the shock I'm afraid the THUD will increase exponentially. All parts were new and installed recently.
Anyone have any suggestions as to where to start?

I have this exact same issue. Basically even small cracks and Indentations in the pavement feel like I’ve run over craters. I took the car back to get upgraded z4 and m3 mounts, let’s see what happens.
