Positive Camber!
 

I got an alignment last week, and my front left side had -0.6 degrees and right side had +0.5 degrees. The outer edge of the right tire is tearing at spots due to the positive camber.

I did a bit of research, and it seems like the front camber on the X5 is only adjustable via three available length control arms. Since BMW only warranties alignment for 2,000 miles, I'm wondering which control arm I should buy to put my camber back inline.

I came up with the same thing you did from a quick search, three different length parts or adjustable camber plates. I can't really help as to which size arm to buy.

I am not sure if the e70 is like the e46 or e90, but in those cars there is a camber alignment pin on the strut housing (under the plastic cover). You can remove this pin and adjust camber a bit. I haven't looked on my e70 to see if it also has a pin, but I am guessing it probably doesn't.

I have Vorschlag camber plates for my E46 M3, but the E70 X5 doesn't have the same type of suspension setup. AFAIK the only way to adjust front camber is using another camber arm, but I'm not sure if we'd use the lower or upper control arm.

I am not positive, but I think you replace the upper arm.

What were your toe settings?

It looks like I need part #16. Should I get the -30 min or +30 min model?

My toe was set at 1/16" on both wheels. Nothing too drastic.

I don't want to steer you wrong. I would call your local dealer and ask them which one you need to increase negative camber.

My mechanic said I need the one that is -30mm :) I'll keep everyone posted. Here is the results of my original alignment. Keep in mind the front end was not adjusted.

I would like to see the results. I still can't believe we are forced to physically change out a part to adjust front camber.

Likewise! I have Vorschlag camber plates on my M3, so maybe I'm spoiled by the easy camber adjustment lol.

How did it get so bad to begin with?
