Remove mirror cover and fender side vents?
 

Anyone know how to remove the exterior Mirror covers and the side vent with the 86 logo?

I can't speak for the Scion.

But for the Subaru:

Mirror covers can be removed by hand. I usually use my fingernail or a trim removal tool to make a gap. Then they pull off.

The fender garnish requires:
Heat gun to loosen the sticky tape
Wire to slide through the sticky tape
Moulding remover to remove the six clips

Could be different on the Scion though? idk.

The faux vent or the 86 emblem? The 86 piston ornaments are held on with adhesive and two alignment 'pin', similar to the front badge.

wish someone would do a DIY for this. Thinking of taking off the 86 Piston to repaint it.

someone already said how it's held one. It's 3M double sided tape with a plastic guide pin on either side... the pins aren't lined up though.

The seems are tight for removing the side mirror caps. A credit card, a microfiber towel, and some blue mask tape helped me.
