i plan on lowering my 330xi with the HnR springs too. I think the reason for the higher springs on the xi so it will have more clearance in heavier snow conditions, not because of the actual AWD transmission. the wrx sti and evo are awd yet they can be lowered pretty low. I dont plan on driving in heavy snow and i am planning on getting aftermarket wheels so i will defintely be lowering mine.
