Soundproofing 2015-2021 WRX STi (P5): A-Pillar Insulated

This time around the A-Pillar plastic was driving me insane. It just seems like once these pieces start, they really start. It was literally only a week before the A pillar plastic on my WRX STi started going crazy. It rattled more than the rear-windshield plastic piece, and that's hard to beat. I added a little bit of sound-insulation material to help prevent the rattles, and that's all that I can do since the air-bag is in the way. Hopefully it's enough.
