I have an 06 330xi. I have been looking to lower it and want to make sure I get the correct information. I am only going to have the car for another year or so, so I do not want to dump 1800.00 into coil overs. I am going to do springs only. I see that many members with newer cars such as the 335xi have posted on this topic, but not many for the older one such as mine. Can you put 330i lowering springs on the xi?
