In order to do a fakie 180 frontside you're going to want to have enough height off the ground in order to be able to rotate mid-air. Some people like to get a lot of height off this trick but I like to keep it nice and low down to the ground as if it were almost a pivot.
What you're going to do is you're going to pop a fakie Ollie, hit the ground and pivot your shoulders just as you're about to land. So instead of all four wheels landing on the ground just two of them will hit and then you're going to pivot and then land the trick fully.
Now, some people have difficulty with this trick because it's not easy to rotate your board so generally what I suggest you do is you try to be able to do a fakie ollie, land in manual and then work on your pivot afterwards.
Now remember, some people like getting big turns off this one. I like to just have a small pivot, have two wheels off the ground so if you can manual and fakie or if you can do a fakie Ollie to manual then you're likely to be very good at doing this trick.
Take your time, don't go too fast and understand that this is a bit of a difficult trick. It took me a little while to get. If you want to make it stylish just take your time with it. If you really want [??] points as a bonus, you can try grabbing the nose as you're midway through your rotation.
And that's how you do a fakie 180 frontside.
