this guy over on the M5 forum seems to have come up with a hackjob method of adjusting front camber without having to buy a camber correction kit.
Having just installed my third set of front tires
due to really bad inner tire wear in roughly 4 years, I'm open to trying just about anything and reaming out the strut holes to make the camber adjustment seems viable.
I should point out that I did do a semi complete front suspension overhaul a couple years ago, but that I am riding on coilovers and no, I don't wish to switch back to stock ride height on stock struts as a solution.
An interesting corollary here is I did the alignment front and rear myself and the rear tires
are wearing perfectly and show no signs of wearing out at least for another year or so. The nice thing about the rear suspension on these cars is that they do provide an eccentric bolt to adjust camber.
If I were to do this what I am currently experiencing is really bad inner tire wear (front tires
only) which I assume is attributable to a combination of toe and negative camber.
Which way should the top strut holes be reamed to introduce more positive camber, say at least 1 degree if not more? I assume these holes should be reamed towards the outer fenders and not towards the engine.
