These cars steer beautifully if the wheel alignment is correctly set up so I do not see any point in locking the trunnion springs. Braking is also very good.

On the subject of wheel alignment, I found that the front axles on all of the 3 1920's cars I restored to be out of alignment. Not visible to the naked eye but all needed significant correction to the kingpin inclination angle. This work is easily carried out by truck repair specialists.

I drove only one of my cars before the front axle was aligned and it did not steer well but was excellent after only minor correction to the kingpin inclination angle.
