Q: What warranty and price come with these?

UP backs the rear camber arms with a 2-year warranty, which they offer because they are confident it is the strongest arm of its type available. The set is currently $571.57, marked down from $695.00. Installing them will not automatically void your Tesla warranty either; under Magnuson-Moss, Tesla must prove the part caused a specific failure to deny a related claim, so keep your stock arms for a possible return to factory.
