A common remedy for chronic ABC problems is retro-fitting a conventional passive coilover system (Arnott, Strutmasters, and others), which owners describe as more reliable and cheaper than replacing the OEM hydraulic system. One converted car documented a roughly $6,200 job; some owners keep the ABC hardware onboard for 'nostalgia,' and enthusiasts remain divided on whether conversion helps or hurts value versus a properly sorted ABC car.
