Sometimes you are lucky and can catch the car, but most times people are on the throttle when the car suddenly turns.

When I set up my car I center the servo saver, then set the Endpoints to be almost at the limits of the physical left and right steering.

Then when I get to the track I set the D/R to be just enough to make the tightest turn.

When driving and I notice the $150 ultra high-speed speed sevro is turning the wheels faster than the car react and scrubing the tires I then adjust the servo speed slower. Not all radios have servo speed adjustment, but then again not all racers have ultra fast servos either.

To give an example of how much servo travel and speed is needed I'll point out my oval radio settings on a 170' runline oval.

EPA 105% L 98% R
D/R 38%
Servo Steer Speed 40%
Servo Return Speed 60%
