Q: Do I need adjustable camber arms for my lowered Tesla?

For most lowered cars, yes. Factory Tesla arms have a fixed adjustment range that is adequate at stock height, but once the car is lowered, residual camber sits outside spec no matter what the alignment machine does, because the arm has no mechanical travel left. We manufacture adjustable camber arms for Model 3, Model Y, Model S, and Model X, and for heavily lowered front ends we also offer front upper control arms that expand front camber and caster range.
