[s-cars] tire wear on a lowered cars

[kbogach@comcast.net]

Hello.  
I have SP8000 tires on lowered UrS4 '93 with 2B camber plates.  Camber is -0.6, everything else is spec, according to my local STS shop.  By the way, they did mine both 200tq (stock suspension) and it looks perfect after many miles.   There is an excessive outer edge wear on the front SP8000s.  Plus,  I was told, there is not good wearing pattern overall:  the adjacent edges on two adjacent treads are of different hight (different wear).  I tried to depict it below.   
Before I shell off  $200 for alignment at a dealer I'd like to ask question:  if the current alignment is actually what is on the shop's printout,  shall I see obvious uneven wear on 10Kmi old SP8000s?  Can it be specific to performance tires?  These ones my first performance tires ever.

Thanks.
Konstantin.
