Does anyone run a Hydraulic Lift System on their suspension? For reference: http://www.kw-suspension.com/us/kw_hls.php Does anyone know of a company who manufactures a system that is suited to a Z32? Has anyone installed a Hydraulic Lift System on their coilovers as a bolt on? If so, then what type of coilover is being used? Lastly, if you have experience with them then is the height gain useful/adequate for obstacle clearance?
