Most racing components are designed to be as light and compact as possible. Unfortunately, metal components can sometimes fail due to oil starvation or metal fatigue, and racing teams often lack the time to redesign and retest before the next race or cannot modify the parts due to regulations. WPC Treatment is a surface treatment process that enhances oil retention and fatigue strength in metal components. This micro shot peening process creates high residual compressive stress, helping to prevent oil starvation.
