[Alan Roehrich]

There was a time when people built cars with a short upper bar to make them leave harder, usually for use with a soft leaving foot brake automatic combination, with a lower HP/torque engine.

Often, if you do other things to make it leave hard, such as installing a trans brake, installing a lower gear ratio, converting to a stick shift, or going to a combination with a lot of power, it makes the car very violent and hard to tune.
