02 accord sedan exL

ok since I have been having this problem with my rear camber (even though my car is stock height, stock springs etc....) my conclusion is just to get a camber kit and correct it that way.
I bought tires (Falken ZIEX 512's in April and already have to replace my rear ones becuase of uneven tire wear on the inner side of the tires....

How hard is it to install the camber kit? Can I do it myself and then take it to get adjusted. If its an easy install id rather do it myself so i wont get charged an arm and a leg for the price. I removed the tie bar i had because i felt that caused the problem. I removed it to late cause I figure the tires already wore out and got that uneven shape.

Which camber kits are good to get?
eBay as some and not sure which brand is preferable.
