Coil Over vs Torsion Bar

The coil overs can be adjusted for ride or control, maybe better response. Personal preference plays a big role but for the street rider, torsion bars should suffice. IMHO
I have done high speed road courses(max speed under 120)with L & R turns,hills and bowls with t bars and have enjoyed the handling ability of my little A body.My future goals are to install workable headers to increase power and speed.Never too much,right?
