Is that toe in or out?
Even if it was toed out 1/16" total, that didn't kill the inner shoulder.
High negative camber will kill the inner shoulders with lots of street use. The inner shoulder is taking on more of the load (vehicle weight). Most (sane) drivers won't drive their car anywhere near as hard on the street as they do on the track, so our street use static negative camber requirement is a lot less. Also we do much more straight line driving, which does not subject the tire to any lateral forces but continually loads that inner shoulder.
Another factor is that these are strut cars and the camber gain is not adequate. And the caster could be better, but, while adding more helps the "dynamic camber" especially on the unloaded front tire in a turn, caster affects other geometry of the front suspension. Adding more static negative camber is not a total solution as the unloaded tire now is being drug on its inner shoulder.
Pumping up the tires beyond the recommended cold pressures can help some, but at the risk of the car becoming too darty and a loss steering feel.
