ADVANCED PRO PLUS is a 2-way coilover system with inverted mono tube dampers made for vehicles with MacPherson strut type only. The system allows you to adjust the rebound and compression damping Shock & Spring Seperately. With an external reservoir, this system provides extra oil capacity to dissipate heat well, which allows you to operate these coilovers for long period and improves performance & handling due to more stable variations in damping rates during the high speed driving. The braided hose is utilised to connect the external reservoir through upper mounts; this is ideal to allow for variable mounting locations when the external reservoir is mounted.
