These are not production cars. No one should ever get in a race car with out a tech. inspection that includes checking all nuts and bolts, and looking for cracks. I know these are not race cars either, but they do have one thing in common, they are not production cars (and most have more than race car power). OEM's develop tourque specs for every critical part by testing fasteners in a very scientific way, and then assigning a torque spec for each fastener, and then they continue to test the assymbly in harsh but real world conditions, over and over. This type of R&D is not free. If you want to own a specialty car like this, you need to have repect for what it is, and do at least an annual check of all critical nuts and bolts. If these companies were to held responsible like an OEM, they would be driven out of business very quickly. Could you imagine if NHTSA had jurisdiction over our hobby?
