Manual Steering - Standard vs Fast Ratio?

I used the Flaming River 16 to 1 manual box when we built GTX-R. It had Viper spec wheels and tires. IF the car wasn't moving it was almost impossible to steer. It was tough even when moving.Handled well though.
On a A body with smaller tires and the car being lighter it maybe ok. All I know it was wrong for our car.
