Added for top models ( designated'Sport'in the U . K ) were wheels with 205 / 45VR16 low-profile tires, larger brakes at the front and rear, additional chassis stiffening braces, a limited slip torsional rigidity.

Pre-production units of the 128, fitted with custom welded bodytubs, demonstrated that this construction was too weak for tough off-roading, had insufficient torsional rigidity, and easily suffered hull-ruptures at the front cross-member, as well as in the wheel-wells.

The wing was of unusual construction, having a single main spar, forward of which the condensers of the engine cooling system formed the entire leading edge of the wing, the combination of the two producing a'D-box'spar of great torsional rigidity.
44.
The changes in construction from B4-PC11 through A and AF variants were to add extra ribs through the fuselage section ( increasing torsional rigidity ), and to modify the control column stops and shorten the rudder, giving greater control surface deflection.
45.
Torsional rigidity went up, and, with the addition of front suspension that added double wishbones, trailer arms and a stabilizer bar, and a 4-link rear setup that includes coil springs and a stabilizer bar, handling went from mystifying to quietly subtle.

Unveiled at the 2013 New York and Frankfurt auto shows, the second generation Soul is based on Kia's Track'ster concept, and offers an increase in torsional rigidity of 28.7 %, wheelbase increased to, width increased to and the same overall height of.

He commented on the car's bland styling which was justified by Fiat's Paolo Cantarella on the basis that the designers did not want to create too much " visual noise . " The body was reported as having twice the torsional rigidity of the outgoing Thema.
48.
The standard perimeter-type frame was abandoned, replaced by a unit with rails laid out in the form of an elongated " X . " Chevrolet claimed that the new frame offered increased torsional rigidity However, this frame was not as effective in protecting the interior structure in a side impact crash, as a traditional perimeter frame.
