ZX Series Coilover Suspension Kit - E46 Convertible

Product Details

For the E46 Convertible enthusiast looking to bridge the gap between a high-end street car and a dedicated race machine, the BC Racing ZX Series offers an unparalleled engineering approach. By moving the compression valving to the external canisters, the system maintains its integrity under high-stress, high-temperature conditions, effectively eliminating "damper fade." For the E46 Convertible—which lacks the structural rigidity of its coupe counterparts—the ZX Series' advanced damping provides the stability needed to maintain a flat cornering attitude. The system features bearing-mounted spring platforms to eliminate "spring binding" or popping during tight maneuvers. Fully rebuildable and customizable, the ZX Series is a long-term investment in the competitive potential of your BMW.

Key Features:

• Enhanced Thermal Management: External canisters keep fluid away from brake heat, maintaining valving accuracy lap after lap.

• Camber Adjustable Top Mounts: High-quality aluminum plates eliminate factory rubber "mush," providing direct, unmediated steering feedback.

• Independent Ride Height: Threaded bottom mounts allow for ride height changes without sacrificing suspension travel or preload.

• Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme track vibration.

• Custom Valving Available: Each kit can be custom-valved to match specific driver preferences or extreme aero/tire setups.
