Alignment gurus: best C/T specs for DD/tire wear?
I'm due for an alignment pretty soon and there are lots and lots of conflicting opinions about what works best for a daily driven street-only vehicle. My car is a 2006 330i, moderately lowered with the FSD/Eibach combo on staggered 19's.
Option 1 is to get it aligned to factory by BMW. That's easy and it might be a good choice. However, I've heard that the factory specs are a mix of straight line and good handling with several compromises thrown in for fun, along with pretty high tire wear for people who generally travel in a straight line. My question is, are any of you running modified alignment specs right now for street/DD that minimize wear while also providing enough grip to keep it enjoyable on back roads and stable on the highway? Post up your F/R toe specs and rear camber and anything else we can/should adjust. Thanks! |

What I have always done is -1 in the front (or close to that) with .1* total toe in and -1.5 in the rear with .2* total toe in. This will be great for a daily driver and still decent for back roads while not wearing out tires prematurely.

Zero camber and zero toe will lead to best wear characteristics, if all you care about is tire wear. Unfortunately zero camber and zero toe makes the car handle like sh*t and dart/wonder/tramline like crazy.
So typically, -0.7º negative camber (slight wear on the inside of the tire) and minimum toe-in at 1/32" or 1/16" (slight wear on the outside edge of the tire) will result in a fairly even wear, SOME acceptable handling characteristics, and good to excellent high speed stability for a car that's never going to see road holding G forces remotely approaching 1/2 G.

Thanks for the input guys, I've seen lots of really helpful posts from both of you and I appreciate the insight. Ultimately tire wear is important to me because $, but I don't want to have zero camber/toe/fun either.
btw Hack, I always get a kick out of your sig. |
