generally to all dfp and g25 users ... always use 1.0 for wheel compensation (unless you belong to the crowd that likes to change their driver settings all the time)
and for the record my settings:
dfp 720 race: driver: force 100 deg 720 lfs: force 80 deg 720 comp 1
dfp 200 drift: driver: force 100 deg 200 lfs: force 40-50 deg 180 comp 0.8
dfp 720 drift: driver: force 100 deg 720 lfs: force 40 deg 720 comp 1 (not like i can drift at 720)
im strong enough but with those settings i get massive oscillations on the straights 100/80 is about the highest i can go with an acceptable level of oscillation
