Using aircraft-grade PTFE stainless, Teflon-inner lined hose, we've achieved a design that not only provide performance but also longevity. Compared to standard OEM rubber hose, stainless reinforcement resists expansion over high range of temperatures, as well as to keep contamination at minimum. Due to this characteristics, fluid-dynamic forces are translated with much higher precision, from pedal to clutch mechanism. Recommended for anyone who is serious about vehicle control, in any motorsport stage.
