Tire shaving to fight premature camber wear?

No uneven wear despite the camber clearly seen on the picture.
I think the problem with uneven wear is not a camber issue.

I see yes no sign of wear, and yes the camber is obvious, I can see how toe can grind tires down more, what tires are they turanzas?or diamaris?

i have 19 inch wheels and the sports package and don't seem to have any uneven wear on the rear tyres, oops i have to rephrase that, ive just gone and stuck my head under the back of my car and surprise surprise the inner 1 inch of road surface tread is bald particularly the right hand rear, the tyres over all are due for replacement as they are about 1 mm off the wear bars, dam should have looked closer before i posted hehe.

i'll get an alignment when i get new tyres and see how it goes ( booked in for next week)

the mechanic i use builds cars for the Australian Porsche cup and really knows his stuff so we'll see what he reckons, he has done good jobs on my previous cars

please let us know how it pans out with you porsche mechanic fella, my guy couldn't get the camber to the level i wanted, toe was ok, but camber on one side was just within factory spec on high side, still not found a decent mechanic who can tell me what parts are worn or bent etc

It doesn't reduce the wear, it evens it up.

i see, across whole width of tire i guess by aggressive cornering etc.

That's right. It flattens out the contact patch on the tyre that's taking the load - ie the outside tyre.

Tires are Michelin Diamaris and I think my driving style is quite standard, except when I'm alone

[omodos]

got the same on my rear and maxis in the front that are really good and aggressive looking and wearing well, yes yes i understand driving alone has a different feeling, you can listen to your own style of music, and drive however you like without the constant mind the cat mind the cyclist blah blah

I took my 2001 4.4i X5 w/ sports package to the dealership to get the wheels aligned because the very inside 3/4 inch of my tires where burning off while the outside looked absolutely untouched. BMW (Bavaria BMW in Edmonton, AB) said that they aligned it to spec (which wasn't much of an adjustment) but it continues to wear out the rubber on the inside. They also said that it could be a worn out part but couldn't tell what specifically was worn so they offered to to start putting new parts in piece by piece at my expense to see if anything helped but couldn't guarantee me that anything would work... this didn't instill any confidence in me from these guys.

I looked on bavauto.com for this rear camber kit but only could find a camber kit for the front.

I know lots of people have had the same issue but has anyone ever fixed this problem? Speculation is not helpful.
I'm considering selling it because it's too expensive to put a new set of tires on every year just to wear out the inner 3/4 inch and leave the rest of the tire virtually untouched.

There isn't one part or one change that will fix everyones issue. If you can't get you X aligned to spec by a qualified shop, then you need to start trying to figure out why that is in your specific case. Your issue may not be the same as the next persons. Will it not align to spec on just one side, both sides, etc? Unfortunately, if you can't get it to spec by a qualified shop, something is broken, bent, etc. and you will have to find what is wrong.

Also, how many miles did you get out of your last set of rear tires and what tires did you have on there? Some tires will last longer than others. Did you maintain proper pressure the whole time? I mean, I can say that the insides of my rears were nearly worn down to metal and the outsides looked good, but then again, this was after 40,000 miles, which is completely acceptable.
