21mm Piston Coil-Over System

It is built with a cast aluminum outer body, precisely CNC carved, and incorporates OEM rubber seals with a specially designed piston and one-way valve. This design significantly reduces pedal travel by approximately 45% compared to stock, enabling faster shifting by requiring less movement to complete a gear change cycle. The QMC uses a 21mm piston to move the same fluid volume as a stock 15.8mm piston, leading to quicker engagement and disengagement. This performance part is particularly beneficial when paired with a short shifter, as it helps to re-synchronize the timing between hand and foot controls, maximizing the benefits of both modifications. By reducing the potential for mis-shifts and improving clutch engagement feel, the QMC contributes to a more relaxed and natural shifting technique. It is designed as an OEM replacement for worn stock clutch master cylinders and is compatible with all aftermarket clutches.
