WebFracture strength is the value corresponding to the stress at which total failure occurs. Stiffness is how a component resists elastic deformation when a load is applied. Hardness is resistance to localized surface deformation. Normal Strain: deformations that occur perpendicular to the cross-section; normal strain is caused by normal stress. WebThe chassis feels balanced but isn't as stiff as something like a 3-series. The car is eager to rotate, aided by the near 50-50 weight distribution and the low center of gravity, but you're always aware of the weight of the car, partly because the stock suspension isn't up to German or JDM sports sedan standards.
