Hey guys,
manufacturing a car takes time, and hard work, specialy when you out source to other contractors. Parts don't allways get approved. so a whole batch would have to be reran, and inspected. When you out source, you don't have control of the people and machines making the part for you, so you can not catch things in advance. Specialy when the part is a new never been produced by anyone before type part, and specialy when that part will help the cars performance alot. So you don't Really want to leave that part out of the box. Don't be suprised if the car does not ship at the end of february. Just cross your fingers, and prey.
