Two decades ago, choosing lightweight materials for a performance car was simple, although somewhat limited material-wise. Still, knowledeable enthusiasts understood less weight equaled better performance. In order to shed weight, you used fiberglass & aluminum, although titanium was available, it was cost prohibitive. Smart guys used chrome-moly steel for fabricated parts, using stronger tubes where needed & paring weight elsewhere. This process is still in use today.
Breakthroughs in materials & a growing aerospace market for high-tech, lightweight products accelerated the evolution of racecar construction through the 80s. Sharp minds noticed different materials available to replace fiberglass (and in some cases, steel). The most common was a Kevlar-based composite, but had it's drawbacks, such as eating jigsaw blades during trimming. That's when carbon fiber composites began to enter the racing & general aviation marketplaces.
The Material Facts
Steel, aluminum, titanium, fiberglass, & carbon fiber all attempt to achieve the ultimate yet often elusive strength-vs-weight criteria necessary in a performance car. However, they differ from each other in the strength, stiffness, weight, fatigue resistance, corrosion properties, & so forth. For example, using aluminum or titanium in the same tube dimensions as a traditional section of steel will reduce weight, but will also produce excessive flexibility. Because of this non-ferrous metal structures typically have a larger mass than an identical steel version (esp high strength strength) in order to regain regidity.
