I wouldn't give them any room to deny your warranty. This is from page 149 of the owners manual.

It says should not, not cannot. It also doesn’t say anything about invalidating your warranty by what you provided. This statement may have more to do about the tires provided on the non Z51 model over anything else.

OP, if you are tracking it I would get the Z51 and magride and before you start swapping everything out track the car a few times stock and then decide what mods you want to make.
