Polyurethane as a material choice has little to do with "stiffness", the hardness and shape of the polyurethane is what determines how stiff it will be and must be tuned to the application. If you look at the pics, it's a much larger isolator. A larger softer isolator, with no air gaps. The rubber rots, the poly is more resilient. True the OE mounts can last for 20 years, and so will these.. they do offer better damping with less movement than stock, but as to why you'd want to buy ours for $167 when you can buy cheap ones for $36... most people won't. Unfortunately for us we didn't yet know about $36 alternatives. Is it worth the price difference for our mount? Depends on how much money you have and how far you are trying to take your van repairs/improvements.. it is without a doubt a better mount than stock for both isolation, motion control, and longevity. But again for most likely not worth it... so suffice it to say, only 10 of these mounts were/are ever going to be produced. As to any other reasons you might want to buy anything Bostig over OE, all I would have to say there is look what VW has done with your money, and look at what we are doing with your money, it's your choice. They will continue to discontinue while we're trying hard to make it practical to keep something practical practical, with passion, innovation, genuine care, and a dose of insanity. A little bit of support to us goes a lot further than a little support to them not just in terms of how it is used, but also how it is appreciated, I guarantee it. Jim
