I haven't looked at your PDF but it sounds like the document we've all signed (ADM owners). Ie. "normal"
They should really tell you about these conditions when you buy the car (before you sign a contract) however I am sure if would likely baulk too many new prospective buyers....
From a warranty perspective there really isn't much difference with most other manufacturers ie. If you break it on the track, don't expect Nissan to fix it. The 'gotcha' in this case is the post track inspection, where they will download all fluid temp history, and thence make you replace them if you have exceeded thresholds. This wasn't for me, so I essentially threw away my warranty, because in the end, if you break it at the track, you have the factor in the worst case/likely scenario (you'll have to pay anyway). I am sure there are cases where Nissan replaced track abused bits, but for me I just didn't think it was worth it.
If you're going to regularly track the car, the whole track inspection thing (and subsequent costs) just wouldn't work. I think you're better off finding a great mechanic and ditching the warranty. But if you're only doing one or two track days per year... Perhaps stick with warranty and all the constraints that come with it. It should be said that you can acquire superior fluids and components and other consumables far cheaper than anything Nissan would put in your car. They is a huge aftermarket for this car now.
