I think your squeak/rattle warranty is completely void and maybe some really weird things like engine mounts but the rest of the car is covered.
I could see a dealer trying to claim that the harsh ride caused a problem with your nav system making the screen fail or something but you should be able to argue that out of them instead of going to court. Stock is safe, aftermarket is questionable and up to the service manager that you're dealing with.
Isn't the maintenance like 12k miles? I did the h&r install in about an hour but by the time I hit that I will have coilovers with adjustable camber but I will pull those off for the oil change.
