[QUOTE="The Necessary, post: 69148, member: 302"] Lee, your logic is sound, but wrong. What you fail to see is the knock on effects of stiffening the front sub-chassis, a crumple zone, on the rest of the car. Specifically the passenger cell. Yes, your "stiffened" crumple zone *MAY* now work at a higher level of impact (in a way that we cannot determine), but what happens aft of that? Have you also strengthened or stiffened all respective parts/components related to your now "stronger" (we cannot tell) crumple zone? Please, foamed door sills and A/B/C pillars do not strengthen the passenger cell agaisnt frontal or rearwards collisions. Thery *MAY* work in certain roll over and/or side impacts. Hence, I do believe that you have not "Done It Right", and not enough research has gone into this mod. As for the rest of your mods, like Kev says, it is all VERY VERY subjective- stick it on a (still very subjective) dyno and lets see the results, if any. As for your arguements about why don't manufactuerers use these "wonder" products, let me give you a little example; Stainless Steel vs. Rubber Brake Lines. Now, WHY don't manufactuerers use SS brake lines? Because Federal (that's US law) dictates that all brake lines must survive a 100,000mile fatigue test, something that SS lines will never do. But did you know that? Hmmm... [/QUOTE]
