Demon Camber!!! Help!!!

Okay, I got a camber kit put in and my alignment done and now my tires are wearing again after 3000 miles and the mechanic says the camber kit is to flimsy to hold it in place so now my tires are gonna be gone after another 3000 miles. what do i do??
It's an ingalls style camber adjusters...

Camber kits vary in quality. Eclipses use RevoTechnica camber kits. wait...ingalls "style"? if its what I think it is, they are not ingalls...they are copied...anything "style" means a copy...
