Oh, that is a very outdated picture of my car! It looks like this today!
My current setup is around 0.26-0.27 Cd. With making some fine tuning adjustments such as
-100% grill block, top and bottom
-front gaps sealed
-wheel skirts adjustment for a better fit
-something else small that I forgot
Im hoping to crack 0.25. With the boattail, im hoping for <0.20 Cd.
