Well it was a combination of changes. Firstly the steering box cars had straight or square cross heads and positive camber to lighten the steering. slowly from their racing experiences the camber was straightened out to run neutral and then eventually negative and a greater caster angle was introduced. Toe was also played around with to try and keep the car from busy steering too. The older cars were always going to be harder to smooth out the steering hence the introduction of the damper blade.
