Yes. E.g. with car5-trb1 you have the best grip with 10% slip, slowly 
dropping then to 88% of the best grip. The drop-off etc. depends on the 
parametrization of the model.

So how does you ABS work, per wheel or in the robot with the brake? If 
you just operate the brake it could be that the brake-balance does not 
fit yet (maybe you lift the brake just because one wheel is a bit 
"locking", so your braking distance might be far from ideal).

Which car did you use, what are the test conditions (e.g. track, car, 
initial speed, etc.).

Kind regards
