Whats the benefits of changing torsion bars

As the years have rolled on from the mid-sixties or earlier to present time suspensions have gotten stiffer, more competent, and able to provide vastly better handling. By changing to stiffer a torsion bar, adding a front anti sway bar, and replacing worn bushings & front end parts, sagging rear springs and shocks these suspensions will provide close to modern car handling. Additional up grades would be sub-frame connectors, and rebuilt PS steering gear to stage two that produces a less boosted modern power steering feel if equipped.

I made these changes to my 67 rag top, and the car is a real pleasure to drive now. No more brake dive, wallowing in curves, floating over rough road, and hitting bump stops, only nice flat cornering, with predictable neutral handling, and comfortable ride.
