First off it's pretty silly to let a couple of opinions from people you dont even know chase you away from your new TC6...I suggest you re-think that thru. Everyone understands the frustration of things not going as we'd "expect" them to, but you appeared pretty hot over a few screws and tight parts when the reality of it is, those are minor inconveniences that any kit can suffer. Also double posting these problems made you appear to be more out to knock the product most of us are enjoying, even if that wasn't your intent.

Lastly on the top deck tweak, you are dealing with a 2mm narrow chassis that works awesome after you get it right, but time must be taken to find the proper tightening sequence and make sure things are in the proper position. I just saw this the other day as I was in a hurry putting back together and found tweak, loosened it up, went in proper sequence while clamping flat and problem solved. No manufacturer is going to be able to solve that for you, a calm clear head and a little time to learn the chassis will though.
