These are not the type of clamps im referring to. The clamps are more like two flat steel bars tightend by bolts that are just beyond the width of the springs. Much more clamping power then these clamps shown in the link.

IMO, Clamps or different springs are your fix.

1.El cheapo, clamps. And they can work.

2. More bucs, SS springs

3. Caltracs.
