[QUOTE="Jeff Furrier, post: 718210, member: 14301"] I dont really know if its a problem or not, but 3.5" higher in the front is for sure laid back but but doesnt seem extreme. Maybe when Im hearing "laid back" Im assming its full lazy-boy style and not just tilted. The Sparco seats have different angles, some are noticeably straight up which can give you leg room..some are more angled that would give more head room. Its pretty common for your shoulders to go forward(drop/hunch whatever you want to call it) and cause your upper spine above the lumbar to bend under the force of a hard stop or big bump in a suspension seat. As you know the suspension in a suspension seat essentially lets you travel 4 or 5+ inches at times which make your belts loose at the worst possible moment. I think its the reason we see so many T12 injuries, its the vertebra right above your lumbar. The reason you like suspension seats is the same thing thing that usually creates the problem. That said, there have been 1000's of suspension seats used over decades without issue in recreational vehicles since the 70's, but they don't belong in cars that are knowingly going to be subject to high G loads. The foam being used in our seat pads in progressive, it soft at the start then firms up before you gut the bottom. Its the same principle as the Safer Barrier walls used in oval track racing, the point is to slow you down before you stop. The more you can slow down before you hit the better, but there are cases where it may not be enough to slow down the 200lb guy when he cases it on a rock. The amount of foam that can be used is obviously limited by space. The Egg/Nerf analogy is sound and makes the point for padding over suspension, what would have happened if the egg were suspended? It would bottom out and break or spring up and break. Think about it this way, what happens when you jump on a trampoline compared to a foam mattress? Which would you rather be sitting on in your car? Poke, your set up look good. Do you have a pic of the lap and sub belt? Spine pic with T12 noted- [/QUOTE]
