When a chain is too tight, it seizes

"It's true. Mounting the torsion bars causes the chassis to stiffen. However, rather than increasing grip, it is perhaps fairer to say that there is an increase in reactivity: the chassis responds more quickly to commands and, consequently, there is greater initial grip. It must also be added that everything else depends on the responses of the chassis: in short, if I want more grip, the first step is to use bars, then take a look at which tyres are being used and the condition of the track".
