All metal flexes, but alloy rims flex less than steel rims. Now this flexing is probably not much of a problem for road cars, but people who race on tracks drive at speeds up and exceeding 140 mph for long periods of time. When you apply the brakes at these speeds, the heat build up in much higher than when you stop nice and slowly in rush hour traffic. At night, the pit crews see a slow red glow from the rotors, calipers, and pads. The heat and vibration of running at 140 mph will loosen the lug nuts, so you want metal in the rim that does not flex as much and will dissipate as much heat as possible. Alloys do have an advantage over steel besides looks, if you race your Saab on the track. Just a thought, is it remotely possible to run 140 MPH steady on the Autobahn, if yes then here you might want alloys. You would need Z rated tires.
