The VP (Variable Pressure) clutches adjust the static pressure by changing the position where spring pushes. The VP are named after the diameter of that position: 68mm, 84mm, 95mm. The IV is short for involute. The arms that press down onto the pressure plate have an involute curve and so our clutch plate became the VP 95Centrifugal force makes more clamping force
Regular clutches have static pressure only with clutch springs. The Lock up clutch has two different types of pressure. One is a Static Pressure, and another is a Centrifugal Force by Lock-up as an additional pressure.
