Many high performance vehicles don't come with adjustable camber including the Plaid. No doubt Tesla should've spec'ed the vehicle from new with sane levels of negative camber given how sticky and awesome the PS4S T2s are, but this is quite readily
addressable in the aftermarket with either shims or insanely high quality adjustable camber arms.
Not ideal, but the option is there to get normal life out of pricey rubber.
P.S. YouTube dude is clearly running a slammed aftermarket suspension setup which increases negative camber all round by leaps and bounds
