I recently read some comments suggesting that SS wire was not suitable for chassis construction because it is too soft. I have used spring tempered SS for years with good results. Admittedly my builds are primarily 1/32 cars where the lower speeds and mass make catastrophic collision damage less likely but some of these cars have been run for nearly a year in worldwide proxy races with no opportunity for repair.
 
I decided to look at "the numbers" and found a custom spring site where spring parameters (wire size, length, diameter, etc.) could be specified and either music wire or SS material could be chosen. After entering the choices, spring properties are returned.  Among these is spring rate, a measure of load per unit deflection thus a surrogate for wire stiffness.
 
Using a 1.4 mm wire diameter ( 0.055112") and holding other factors constant, music wire is indeed stiffer than SS - by about 15-20% - a not insignificant difference but hardly an I-beam to wet noodle comparison.
