The AST lowering spring set for Opel Insignia (from March 2017) lowers the center of gravity while preserving much of the OEM comfort, improving body control and giving a sportier but usable stance. Made as direct OEM-replacement springs and cold-coiled on Wafios machines, they feature a progressive profile. These lower approximately 35mm front / 35mm rear, fit the listed Insignia applications and include a lifetime warranty against breakage.
