Q: Does this suspension package affect my Tesla warranty?

Installing it does not automatically void your Tesla warranty. Under the Magnuson-Moss Warranty Act, Tesla must show that an aftermarket part caused a specific failure to deny a claim, so keep your factory parts in case you revert. Note the possible software-related suspension warning covered above is a known calibration quirk, not damage, and the package is designed to be uninstalled and returned if your car reacts poorly.
