Yes. Likewise, if the OEM car has a static positive rake angle as does the Z4 and you reduce it, then you will do the reverse, and shift weight to the rear. When you start loading the Z4 with driver, passenger and luggage, all that additional weight will progressively load the rear axle more than the front, which will tend to reduce rake angle. If you were to start with zero rake unloaded, then you will soon be into negative rake. Therefore setting static rake, like the setting of all other geometry, is a compromise in anticipation of what might happen in the dynamic situation.
