Front/Rear Camber Kits??

[FeelGoodUnInc]

I had my car lowered 1.5" with Eibachs a year ago, never really had any problems until now.....now I'm having some major negative camber wear issues on both my front and rear tires. I discovered this when I went in for a 4 wheel alignment, both the inside toes of my front and rear tires were completely worn down, in the rear you can even see some of the wires in the tire showing.

I spoke to the shop and they told me getting a 4 wheel alignment would just temporarily solve the issue, I was also told as soon as I hit another pothole I would need another 4 wheel alignment...and he's right, after just a week my steering wheel is disaligned again..and unfortunately I live in Los Angeles in the hills where I have to drive through some of the nastiest roads. So I was recommended to get a camber kit (front and rear) but I can only seem to find a front kit from Bavarian Auto for $300 which is a complete ripoff IMO...doing an online search I can't seem to find any Eibach, Ingalls etc. Are there any other companies that produce camber kits for the X5??
