e46 racks bolt right in.
even z4 fits(just).
even your stock lines bolt right up .
oem homologation ftw
and the rack ratio means a heck of a lot more than the turns to lock. you want to concentrate on the ratio if you are looking to change things up.
example above the later model 330 rack have a 13:1 ratio. (which is actually faster than the e46 m3 rack which is around 14.5:1 iirc)
You can find good shape used e46 racks at a few of the bmw parts guys around these parts.
