I find that, at least with mouse, both the UFR and XFR are point and squirt cars. Cant appply throttle mid corner. So your entry line, entry speed and gearing have to be on point.
On wheel, you can vary the throttle to balance the oversteer and make the car more balanced mid corner, but if you apply too much, the car does power understeer so easily lol.
I remember, in the SRT UFR race at sO2, I was basically point and squirting for the entire race. Meaning, braking, raking the gears, turning in with no power, then power out once the steering angle is smaller. Also helps if you have a mario kart "tippy" set that steps out slightly. Helps pivot the front end more.
