I think a couple of you are missing the point? or at least one.
Nissan has set up the warrenty for this car different because they know people are going to be racing it. But people will also be using this as just a standard sports car who still want their warrenty.
When you race, the risk of breaking something goes up A LOT. When you race your warrenty is void. Many people race their cars, break somthing, then claim it under warrenty. Nissan is trying to stop this. When you race your car you can either accept it as a racing car. Or you can take it in and get the $1000 inspection, this inspection proves to nissan that you havn't broken anything in your car that you could claim under warrenty.
