Asymmetrical wear or rear tyres-any advice?

[Luislang]

My 996 eats the inner edge of rear tyres pretty fast. Alignment check shows the alignment to be dead-on in specification. I have 315x18 rims with Toyo rubber.
Any advice to get more even wear will be appreciated!

Go to the best alignment shop you can find that knows Porsche's. Tell them you want your tires to wear evenly.

Porsche spec align numbers dial in excessive neg camber for a street machine. Try half a degree of neg next time vice the spec (which I’m told is around 2 deg?)
