Well for those who do care, you can buy an adjustable upper link for both rear sides from
BBC Speed & Machine . (Newer cars have a ball on one end instead of both bushings) If you must get a fixed upper link, make it 0.21" longer. One way or t'other set that rear camber to -1.00 and rear toe to 0.15 -- and get 25k-30k out of normal tires, not to mention using 10%-20% less W/mile. (Front: -0.70 Camber, 3.55 Caster, -0.04 Toe) (Acknowledgement to lolachampcar)
All Teslas come with way too much rear camber as it is, at least -1.50, and sometimes as high as -2.60 degrees, which accounts for the tire longevity problems. And an alignment from the SC is completely hit and miss, like they don't know what they're doing. And they won't align it with a lowering kit or an adjustable link anyway, so find an independent shop with an experienced hand on a laser aligner, give him these numbers, and pay their fee. It'll be like riding on rails thereafter.
Just because you haven't known what to do about it before, doesn't mean you should continue to blow it off. Senseless. And you kids get off my lawn!
