Bavauto Camber Kit

[2006E53]

I have 22" on my 06, 4.4 which is lowered on H&R springs. I have been burning up the rear tires. I have decided to install a camber kit. I see the KMAC makes one for about $350. I also located one from Bavauto for about $260 sometime about a month ago.

When getting to order the bavauto kit I can no longer find it listed for an E53. I called Bav and they have no idea they have one.

Has anyone purchased the Bav kit and if so have the part #. Also someone told be the same camber kit is used on E39s does anyone know if this is true?

Any help would be great especially to find an in expensive kit.
Thanks in advance
