Sometimes the gearratio bugs out ... same happend in PCARS 1, but now it is much more frequentSo, something I forgot to mention (@t0daY)
What I noticed in the BMW TCR is that in the tuning setup the Final Gear Ration would be around 4.something
When changing I had the option for 3.something and 2.something, but the option for 4.something wasn't there.
I saw the same with the other gearing ratios where on default there would be different ratios then actually selectable.
I havent yet had time to investigate any futher though
