what's next? Going 60mph or 100mph under some seconds will void the warranty too? I can understand they don't want owners abusing the cars, then bring them in for warranty repair. Seems like they are trying to hide something or something they know is going to break if cars are pushed (weak tranny?) then don't want to repair it under warranty. What's sucks is some people probably do care about the warranty and are going to track the car in stock form. From what read some time ago, GTR's navigation system can tell the ECU where it is, racetrack and stores it. So no way around it.
Btw this is what my friend has to say about GTR's warranty, GTR stripped and putting down 700whp.
