No, a sharp set of drill bits and a mechanics ruler would be great to have. The layout took the longest it's important to note that the further forward you place the wing the higher it will face upwards.
It's hard to see but the back of the spoiler is not touching the body of the car because of the forward position of the wing.
That's with the second stud from the end of the wing at 4.5cm from the body roll at the end of the roof. I found it was just easier to measure the position for the studs as the template is slightly flexible and not exact.
