I don’t usually tune my own cars, but I wanted to try doing a drag tune. So which is the best to use?
For RWD drag, rally suspension. It’s softer so you can get more weight transfer onto the rear wheels.
For AWD, I think rally or race, probably race though. Depends on the car/how you want to set it up.
For FWD drag, race suspension because you want the rear springs really stiff. (But forza stinks at FWD drag builds, which is rather disappointing imo)
