Thanks for the responses guys. It should help. Here's a grand list:
1) Forcednduckshn - DFGT - Force Feedback 8
2) Owens Racing - T500 RS - FFB 6-10 depends in car and track usually 8
3) cicua - G27, FFB=1 (maybe 2 or 3 for light cars), PowerSteer=on. Anything more and much wrists and shoulders start hurting after a few hours of wrestling. G27 is really heavy, has only become slightly better after they added official support for it.
4)Jay2Bizzle4shizzle Dfgt ff=8 (I think), ps off
5)Nepal - G25/ FFB 7/ PS ON
6)Wardez - G27 and run 5 FFB, I'm not sure about the power steering though, never messed with it so it's gotta be on the default setting.
7)Time Attack - G27/ FFB 1/ no aids
I think when I was practicing with the DFGT before the GT-Academy finals, I was running the FFB at 3 IIRC....although things may have changed a bit with the updates since then.
8)R1600Turbs - DFGT / FB 5 / No PS
9) PTP - DFGT 7 sometimes
