The UniSA prototype used modified rack-and-pinion steering from a small Diahatsu. This was not entirely satisfactory:
- the rack (but not the teeth) had to be extended on each end
- the steering shaft had to be shortened
- the lateral position of the pinion and the angle of the pinion shaft to the mounting faces were inconvenient.
The steering will need to be redesigned to be compatible with improved front suspension.
Power steering is not required.
Steering 'feel' is vital in giving driver confidence - feel is complex and involves Ackermann, scrub radius, trail, tyre type, etc. Best done experimentally.
