In Reply to: Help! Toe setting for rear suspension! (Longish) posted by Nivola on August 01, 2001 at 20:46:16:

The gentleman is almost right. The stock car has no adjustments for the rear suspension, including toe.

It IS adjustable, however. You can have eccentric bushings installed in the rear trailing arms. A BMW repair using BMW parts. A friend of mine had this done at his dealership for about $700. My dealer quoted $1,000, and I lost interest.

Most stock cars toe IN in the rear. My M Coupe toes in about a quarter inch on each side. Makes them more stable. Serious autocrossers sometimes like zero toe or some such in the rear - helps you to turn in better.

I decided that the tiny difference would not be worth $1,000 to me. I rarely win or lose by fractions of a second.

Bottom line - if your car feels OK, don't worry about this. Doubtful you could get them to pay for the repair. . . but them I'm pessimistic about such things. Particularly since you may have done this to the car. But I doubt it - prob came that way. Hard to say.

I just got the car back from BMW after having a four-wheel alignment (I had clipped a curb sliding on some unexpected-surprise-on-the-apex-oil).

The final alignment report came back all within spec for camber and caster and toe for the front. For the rear, camber was in spec, but both the left and right rear was out of spec.

Initially the BMW technician told me everything checked out ok, but when I pressed him about the out of of spec toe (the report placed the figures in RED as opposed to GREEN), he told me the M coupe does not have adjustable toe on the rear suspension.

The alignment print for the rear toe figures came back as such:

Left -0.10 (w/specified range of 0.14 to 0.36)
Right -0.68 (w/specified range of 0.14 to 0.36)

Does that sound right to all of you? I was under the impression that the car does have adjustable rear toe. If the car does indeed have rear toe, do these figures necesitate taking the car back for another adjustment?

The car feels ok, but I haven't had the opportunity to push her hard (especially with all that tire dressing they gunked the tires up with, ugh!).

I all just leads me to wonder.

Thanks in advance for the help.
