Just took one for the team, these are cheap enough to buy and try. Like the title says... the M3 mud flaps don’t fit. The fronts can be made to fit but the back ones are way off.
I'm going to wait for the Model Y specific ones as it’s not worth the amount of work it would take for just the front ones, especially if it involves drilling holes in the Y’s wheel well liner.
