Understanding how a car responds to your steering input is crucial for mastering vehicle control! Two key parameters define this behavior: steering lock and steering ratio. These values shape how quickly a car turns, how much input is needed, and how precise your handling feels.
Steering lock refers to the total angle the front wheels can turn from full left to full right
It's usually measured in degrees: For example, a 540° lock means 270° left and 270° right
A higher lock angle allows for tighter turning circles, useful in low-speed corners or hairpins
In sim racing, matching your wheel’s rotation to the car’s steering lock improves realism and force feedback
Steering ratio is the relationship between how much you turn the steering wheel and how much the front wheels actually turn.
For example, a 13:1 ratio means turning the wheel 13° results in 1° of wheel angle.
Lower ratios (e.g., 12:1) give quicker, more responsive steering, ideal for tight, technical tracks.
Higher ratios (e.g., 15:1) offer smoother, more stable handling, better for high-speed circuits.
