In my case, as is common with people who are not interested in playing such a game, one can go to your local trusted mechanic who knows the rules and how to get around them... cheaply. I took my car to BeAmbitious (same shop which did the installation of the R35 Brembos, rear BNR34 diffuser, S15 trunk brace, Nagisa brace, Tomei ExPreme titanium muffler, etc.) and had Ninomiya-san there take care of getting my car properly "shakened" (he told me: had to raise the ride height of the car, special bung for the Tomei muffler, etc.).
While the car was with him, I decided to have him install the final external body stiffening part I could find: the CUSCO Tension Rod Bar. I had meant to do this myself, along with an oil change, but laziness dictated otherwise.
Here are some photos from the CUSCO website, to show you what they look like:

The Bar looked like this when it arrived:
Unfortunately, I don't have any photos of the bar installed, because I didn't do the work. I did find this photo on Minkara, you can see how the blue bar bolts onto the inside each of the tension rod mounting points (so in effect, connects the two sides together).
So, what are my impressions? To be honest, I think there is a very slight improvement in how the car's steering feels upon turning, as well as the car's response. That is, on center feel is still somewhat numb (compared to my recent drive in an NSX - and this is the Holy Grail for me), but moving the steering wheel to begin a turn, feels more direct, and the response feels more immediate (so is this an "enhancement of chassis stiffness, rigidity and stabilizes alignment"??). As a result, the car feels a touch more nimble, which is a good thing in my book. But I still want more feedback on-center, I was hoping this Tension Bar would help, but all it did was to further highlight it!
But for the price, a worthwhile mod. Your results may vary, indeed I may be suffering from a placebo effect! I am now beginning to wonder if it might be worth getting my car spot welded in a few strategic places, but I have to research whether the pros outweigh the cons for that. I realize that spot welding probably won't make the car feel like an NSX, but at the same time am curious as to what would happen in terms of how the car feels.
