Just sharing something I've been enjoying for some time now:
https://www.youtube.com/user/davidperel
That is the Youtube channel for David Perel. He's a real life GT driver, and he's also an avid GT Sport player. I follow his videos alongside SuperGT, and TheKie. However, I find David's videos more insightful since he often compares his experience between real life and GT Sport. As someone that has really gotten into GT racing in the past few years, I find David's streams/videos amazing to watch.
I have no affiliation with David Perel or any of the streamers. Just sharing something I enjoy.
