Sorry. The reference to "titanium" was the color. Not the material. All OZ GASS wheels are forged aluminum. I have the OZ magnesium Cattiva (DOT) wheels as well. they are close in weight to the GASS wheels. They also make a non DOT mag version as well that is lighter but not street approved. Easy to tell the material on the Cattiva wheels. Forged aluminum are flat black. Gloss black Cattiva's are magnesium. The Cattiva wheels and the GASS wheels look identical except for the weight reduction machining done to the rim area on the GASS wheels.
