I see lots of discussion on the forum centered around alignment and tyre wear issues, so to give you the specs the cars SHOULD be according to BMW, here is a little chart of the most common values of adjustable items:

Fuel tank should be full when adjusting with 68Kg in both front seats, 68Kg in center of rear seat and 21Kg in boot.

Front Toe setting in degrees:

3.0i/3.0d/4.4i/4.6i......................0.17 - 0.43.....toe in

Rear Toe in degrees:

3.0i/3.0d/4.4i/4.6i........................0.13 - 0.47 toe in

Front Camber:

3.0i/3.0d/4.4i/4.6i.........................0.22 pos - 0.63 neg

Rear Camber:

3.0i/3.0d/4.4i/4.6i...........................1.5 - 2.16 neg

Other assorted useful info:

Wheel bolt torque, all models, alloys and steel wheels..............130Nm - 150Nm
Trackrod nut/clamp............................................. .........................51Nm
Camber on the front IS adjustable on the standard vehicle.
Camber and toe are adjustable SEPERATELY on the rear
Lowering vehicle increases negative camber, so improvements felt may be due to increased camber, not lower C of G.
Wheel spacers greatly increase load on wheel bearings
Worn thrust arm bushes allow excessive lateral front suspension movement, poly bushes improve control and alignment.

For optimum road handling, camber should be 2.0 deg neg on rear with front camberplates bringing front camber to around 1.5 deg neg.

For max tyre life, rear needs setting around the 1.0 deg neg and front to 0.5 deg neg.
