And that is exactly why i started having these discussions with my boss 6 months ahead of the delivery…none of it is a “swap”, its all a part of my factory+ buildtheres no argument....i just wanted to know why people do that to begin with. On the other hand if on day 2 i told the boss.".hey..think i'll swap the suspension out with a 8K one.".I can assure then that would bring a argument.
