You can set the steering lock up to 39 degrees. Try the "Trackday" tires and play a little with the SSW/HSW tire option on the front and rear, as those tires are good for practicing clean driving and are suitable for power slides and drifting aswell as soon as they get above ~120° C - the degradation is low also, so they will last some time too.
