I'm reposting this here as the thread I originally posted it in would only be seen by the young sprogs present.
And, much gratitude to lolachampcar for his research and development of this modification.
This is called 'excessive camber'. Every Tesla made has excessive rear camber, of course not to this extreme, but almost always between -1.5 to -2.8 degrees. This is the reason for the excessive tire wear we see on good quality tires no matter how much we keep air and rotate.
And an alignment from the SC is completely hit and miss, as if they don't know what they're doing.
Rear camber is non-adjustable, so the upper link must be replaced with one that is adjustable. You need that link to be .21" longer so it will push the top of the tire out, to make it more square with the ground. (Specifically 1 degree in, which is optimal)
BBC Speed & Machine (Note that newer cars have a ball-joint on one end, rather than both bushings)
lolachampcar has extensive racing experience and has dialled in the very best alignment settings for our cars. (see threads in Dynamics) Tesla will not align it with a lowering kit or this upper link, so find an independent shop with an experienced hand on a laser aligner, give him these numbers, and pay their fee. Your tires will wear like they are supposed to, your Wh/mile will be lower by 10%-20%, and it'll be like riding on rails thereafter.
