Best CC plates and max neg camber for street

[sk_id]

Ive read in posts from years ago that max motorsports sells the best cc plates is that still true? Ive been runing a 99 v-6 convertable with new bilstiens and 245/45/17 gt wheels n tires. I do auto cross about once a month but its also a daily driver. Ive been having too much outside shoulder wear with -1.2 camber on stock plates and think i need to go the cc route. Also I just added a gt rear bar today to reduce push. According to mm papework i can run min neg camber at -1.3 degree for street use with thier plates. Will that eat up my tires as im still at stock ride height and driving it daily?
