Oh! interesting. Im playing Dirt4 and DirtRally2 and on brake in that conditions and based on handling options, or never stops or it does smooth, maybe even adding less friction or a bit more slip to make it less sharp pressing braking for a better management, so the car still goes but seems slips more from rear(or gets more revs there) giving more precision range.
Also i may increase revs and max speed on 1st gear to help a bit more. Already tried tweaking the engine with limiter time/friction torque/inertia but not does a big thing.
