Lighter is better. Theoretically, reducing unsprung weight helps a car’s suspension system work more effectively. It can also provide sharp and enjoyable steering, enhancing wheel structure performance. The less mass of unsprung, the better behavior of the overall ease of acceleration and handling capabilities for a vehicle, especially in the comparison of racing event or competition. Apart from lighter wheels, a set of lighter lug bolts is also important. (Thanks UG for supporting.)

Premium Titanium Material and Forged Manufacturing Process

Titanium alloys possess high mechanical properties, not only have great fatigue strength and tensile strength performance but also maintain great strength at extreme temperatures up to 400 to 500°C. They are light in weight, also have extraordinary corrosion resistance-a thin oxide (TiO2, titania) layer that spontaneously forms cover on the surface to protect them against corrosion. They have undergone continuous intense pressure to be formed. The strength is greatly enhanced, reaching the depth of hardness needed for its unsurpassed level of security (unlike case hardening which is only a surface treatment).
