Oh, my mistake, I thought I was in the request section when I submitted it, but I guess somehow my phone screwed up and selected the wrong section, since I can't see which section I'm in while composing the request on mobile...
Since my last post several months ago, a lot has happened and now I am moving forward to the stage in life.
Anyways, apologies for the delay, but the latest version is now live. As mentioned before, both simcade handling and ultimate sound swap are now under one mod. As for videos, couldn't really think of how to showcase the huge number of vehicles so simply just did a few laps around the Nordschleife using a vehicle in each class to showcase the difference in handling characteristic and suspension differences.
This will be final unless there are some hotfixes and/or Rockstar decides to add more vehicles.
