Do you need to do any drilling with the mud flaps?
Not the Tesla flaps, nope. You do need a flathead screwdriver (or similar) to pry out the existing clips. Only tool needed.
When you get some run time on those, an update of how well they do would be appreciated.
Will do. Following a first drive yesterday, seemed fine -- still well-attached, no additional wind noise.
