I recently bought the 034 Motorsports Street Density Line transmission and passenger mounts. I received them about 2 weeks ago. I was skeptical when I first received them but Laszlo over at 034 reassured me that these were not regular mount as they looked identical, so Laszlo even went a step further and sent me the Track Density Line mounts also for me to try and to see which ones I feel more comfortable with . I received the track mounts today and let me tell you these suckers are really stiff. I try moving them side to side and they do not budge, a lot different then the Street Density line. I will be trying both sets out in the coming weeks along with my 4 Motion B6 Passat conversion project and I will let you guys know what I think. Here are some pics of the mounts. They look all identical but the rubber durometer is a lot different.
