3 link vs 4 link

[mazspeed]

Ok guys I have some questions on both systems. When I rip the car back apart at years end I would like to know what system is best. I have some questions on both. First the Dynamics 3 link. How much of the rear seat will still be useable? It looks from the install pictures that you almost have to rid the rear seat, but it's hard for me to tell. Another point, I have enclosed a picture of the lateral load bolt that I was curious about.
My questions are these. Is that bolt holding the entire unit from going to each side? To me it seems a bit scary that the entire rear is being held in place with this bolt. Also like my Comp bars, the end links seem to hang a little low as well. Also can you run any kind of rear end, or do you have to run a certain carrier? I see in all pictures that I have seen run the same carrier? It also seems like twice the fabrication for this system then a 4 link? Am I wrong?

Ok now the DSE system. I know a little bit about this already other then the new piece that is now coming in for the fix from the original design. Does anyone have a photo of this piece, and how does it connect to the system? How strong are these swivel links? How do they affix to each other? The top 2 links on the DSE seem very short, is this any kind of control issues with this design? Also the panhard bar that they use in the DSE system to keep the side from going back and fourth seems small. Also what about the rear seat? I will tub the car, so I know that the rear seat will have to again be modified, but I don't think, well really don't know if the DSE system will be as intrusive as the 3 link as far as the rear seat goes. Any ideas on that? I know that with the DSE system and when I tub it, I won't lose my custom gas tank, is this the case for the 3 link??
I don't mean to nit pick each system, but I have to for my own gain. I think both systems are the best in the business from where I stand and I need to know which is best for me. I can drive better then most, but cannot design anything other then custom lighting, so I'm at a loss, so this is why I ask. Sorry it's so long winded guys.
