I feel I owe the community a more detailed explanation for the switch.

TL;DR: Me dumb. 

Last night we realized that, because the car's physics data was unpacked (i.e. not in a data.acd file), it could cause significant problems for people joining the servers, and might put the integrity of the series at risk. We discussed possibly posting the data.acd file here for download, but ultimately decided the safest approach would be to switch to a Kunos car for now, and continue to work with the author of the Time Attack mod to improve it for a future series.
Sorry I set everyone up for the bait-and-switch, but I assure you, as fun as the Beavis Autosport car is, I'll be keeping it in mind for a future series.
Thanks for your patience, and I look forward to the coming season.
