So, I received my buttkicker and extractor in the mail today and before I returned it I decided to test it out and decide what to do afterwards... I AM KEEPING THIS THING! After setting up and fiddling with some settings, it actually works.. Kicks back when you shift or hit some rumble strips or uneven pavement or bump into things etc, and gives a good immersive feeling. It isn't super super precise, so it's not going to make anyone faster, but it's a nice thing to have for the experience.
Here's what I did
Connection: Hdmi from PS5 to extractor, then extractor to TV and then Digital Optic out from TV into my soundbar. Headphone splitter from extractor into the Buttkicker. Done.
GT Sport Settings: Initially before making adjustments, the thing just rumbled constantly.. Clicked in the button to filter out the high frequency, set the knob to about 70, and set volume to something that felt good and that helped a little bit. Then, GT Sport has a sound setting called enhanced audio.. I clicked this setting, turned most of the music off except for menus (but low volume), and then for transmission I set that to +5, opponent engine to +5, engine to +1, and tire squeal to +1, and this feels GREAT! I did only attach it to my office chair though, but will be getting the GTtrack on Monday.
Also, yesterday I cancelled my preorder for the GT DD Pro and made an order for the GT DD Pro express (didn't know it was the same wheel as the preorder otherwise wtf heck yeah I'll pay $150 to have it now lol), but also added the boost kit, Clubsport V3 pedals, and the brake performance kit. Hopefully they ship this out before they do inventory next week and my order gets stuck until after they're done doing inventory.
