I had one of these installed on my 318ti a few years ago. It made a noticeable difference in the way the car feels even in highway driving. I drove around for a day with the thing on the car having been told that they weren't able to install it. The car felt obviously different (i.e. more stable and just tighter), but I couldn't figure out why since I thought this part wasn't on yet. When I called the next day to set up the appointment to have it installed, they told me they did get it on. I went out and checked and there it was. So, I don't think the noticed improvement was wishful thinking since I didn't think it was there. Also, the brace is the lowest point of the car in that area and has taken more bangs and scrapes than I care to think about (Eibach Pro-kit + Maryland roads). It's holding up well. I would recommend it for any E36 that doesn't have one.
