    I’m custom making a set of tdf style wheels on my f12. From my understanding is 812 use the exact same set as the tdf which is 20x10 et48.4mm in front and 20x11.5 et71.6 in the back. But why am I seeing different et across the internet? Some say the rear wheel has 57.3mm et. Does the tdf have different wheels than 812? I need some more info

    Good luck with your new wheels. TDF/812 wheels will fit F12s with 15-25 mm spacers on the rear.

    Why is that? Isn’t the smaller et on the tdf wheel should sit flush with the rear fender?

    Yep. Even if you put 10 mm spacers in the back of an F12 B with either the 812 or TDF wheels, they will poke out a bit.
