Here's the thing - w/stock suspension, had BMW do fancy/ker-schmancy $295 Kinematic alignment w/weights. Result: OK ride & handling; excessive rear tire wear due to broken in suspension gone. Normal wear w/factory camber, yes, but gross, no.

Later: Yellows, Eibachs, M Parts; LSD. Full-on suspension replacement. Other'n LSD, I did the work.

Short of it:

1. Did shade tree alignment....loved the result! But, toe was clearly not quite on the narrow.
   
2. Took to local alignment shop.
   
3. Got it back - ride degraded! Evidently inexperienced with ride height adj suspensions, they mucked it up. How one does that I've no idea - seems cut 'n' dried to me, and I'm not a pro.
   
4. Did shade tree alignment again....loved the result! Chalked alignment expense up to foolery.

The diff:

• My ride now silky
• Turbo lag, she no got
• Brake bounce @ stop, she no got
• Mucho sa-mooth power delivery
• Sweet progressive grip, no end
• Step much smoother, including hyper mileing at speed

Coming to a conclusion here: Alignment is far more important than I'd thought - check every month or so recommended - must have prepared surface.

New vehicles should have alignment checked shortly after delivery & 5k mi later.

Looks like I don't need help to optimize my suspension; learn more about alignment every time I get into it.

If you want it done right....

FYI - Stock alignment specs

Major diff here: Set camber plates to -1.5° & ride height 0.75" lower
