I leave mine at 900° of rotation on the TX base. I adjust the feel of the steering ratio in game at the car tuning in the pits. Works fine & was the design decision by SMS. Some people say they change there's, I tried it. But I leave mine on 900 & adjust in tuning in game. I don't have problems, not even with tight chicane's. Here's link to a thread about this topic.

Example, the BMW that's in Group 5, stock steering ratio is a 13:4.1. That just didn't work for me at Monza Short. I changed it to 12:9.1, that worked great for me.
Maybe because I'm using the F1 rim & not the stock or GTE.
