[mtv not bullets]

my front tires are wearing like mad since i installed an eibach pro kit. I know its due to excessive negative camber and toe-out. Now, what I want to know is what i should do about it, on the cheap. I just replaced a set of almost new tires and I'd like not to have to do it again.

I've heard a lot of people who have said after installing bump steer kits on lowered cars the camber went positive. Is it possible/likely installing the bumpsteer kit and urethane or even new rubber bushings would solve my problem, or should I get the c/c plates instead or also?
