Hi everybody

I am from Hong Kong and l'm a new owner of a 2011 E250 CGI Avantgarde. The car is great in many ways, l just found the suspensions a bit stiffer than l expect.
From the VIN no l know the car is equipped with 677 Avantgarde/Standard suspension, but there are many choices within the category of 677.
So any body knows the original color codes of the suspension springs of this car??

Thanks
