I have a feeling that they made those parts themselves. They are the one making the ETK ttPerformance mod after all. (I could also be wrong, idk?) OT:
Yes, BrynCoops is right, I am the maker of the ETK ttPerformance Mod, you can check it out if you are interested, but the Rennspecht ETK-I is currently not implemented as I am still working on it. The mod is currently in its early stages. But I work on it every day. Learn new things about BeamNG.
whats going on with the wifi there? also, you might wanna fix your settings. because it certainly isnt the 31st of july OT:
