I would recommend dropping that F1 rim, too. Get something round. Then you could up the wheel rotation to 540*, it's optimal. Yeah, ultimately you can be faster with less rotation, but as you're learning, you need more control and smoothness and 360* and less is starting to be very sharp and unforgiving, you have to be super precise.
And - my personal opionion - I don't like suspension FFB setting, I have it either down to about 40 or 50 or completely off, I don't remember at the moment and I can't check. It might seem good, cause you feel the bumps, but it is distracting you from the fee
