I've noticed that if you steer the ETK-I series at or near full lock, the front tires sort of stick there and self-center only with great reluctance. I've also noticed that it has no caster figures listed in the wheel debug app/live wheel data, unlike every other car. Is this a weird corruption caused by one of my mods, or is it that way stock?
Yeah, that bug is also present in the other ETK's well. The ETK-K and 800 series have a mod that fixes it, but no such mod exists for the I-series yet. https://www.beamng.com/resources/etk-800-k-series-caster-and-ffb-fix.36488/
