Manufacturer specifications
Our MZ-Series coilover system proves that you do not need to break the bank in order to obtain a quality suspension system. Designed for a purely street, sport set-up. Spring rates and valving have been designed to be conservative prioritizing ride comfort while still adequately controlling dynamic forces during aggressive driving. MZ-Series Coilovers Feature 30 levels of simultaneous compression and rebound damper force adjustment, camber adjustable pillowball front top mounts, rubber insulated rear top mounts and full-length shock adjustability.
Spring preload is adjusted independently from the damper shock length adjustment allowing to retain full shock stroke at any given height and allowing for further suspension tuning to truly customize the vehicle overall handling feel.
Designed as a direct bolt-on unit. Manzo MZ-Series Coilovers are protected with a 1-year warranty against manufacturer defects.
