At this point I am looking at suspending from the four side mounts, the engineer geek in me says mathematically they will be more than sufficient. The racer in me says I am screwed if I do not go rubber mount. On plus side I am very handy at welding cast aluminum so I am going to mount it hard watch it close and regroup if she breaks. I am building car for wife and she typically doesn't thrash them like I do although she is not above donning a helmet and dropping the hammer at the track! Did I mention she drinks beer and loves to camp in a tent and hunt deer and elk for days on end? And she fishes better than I can? Oh yeah love me a redneck girl! And she patches me and the boys up after hockey games when we try to do things only young hockey players should do. All of which is why I am building the Demon for her as a daily driver.
