ADVANCED PRO PLUS is a coilover system with inverted monotube shocks designed for MacPherson type vehicles only. The system allows you to adjust rebound damping and compression separately. With an external reservoir, this system provides additional oil capacity to dissipate heat, allowing you to run these coilovers for a long period of time and improve performance and handling due to more stable variations in damping levels during high speed driving . The braided hose is used to connect the external tank via upper supports; this is ideal for allowing for different mounting locations when the external tank is fitted.
