Designed for drivers who demand maximum handling precision and track-ready performance, the Megan Racing Swift-Track Series Coilover Kit delivers a significant upgrade over conventional street suspension systems. Engineered for the Nissan 350Z and rear-wheel-drive Infiniti G35 Coupe and Sedan, this system combines aggressive spring rates with track-focused damper valving to provide superior cornering stability, responsiveness, and control.

At the core of the Swift-Track Series are genuine Swift Metric coilover springs, chosen for their lightweight construction and consistent spring rates. These springs reduce unsprung mass, promote smoother weight transfer, lower tire temperatures, and improve overall chassis feedback—giving the driver greater confidence and predictability at the limit. The dampers are aggressively valved and paired with heavy-duty piston construction to properly control the increased spring rates, resulting in a suspension setup that rivals systems costing significantly more.

Ride height adjustment, independent spring perches, and camber adjustment on applicable strut configurations allow for precise suspension tuning while maintaining full shock stroke. This design enables accurate corner balancing and optimized handling characteristics for circuit and road course use. Finished with durable gunmetal brackets, the Megan Racing Swift-Track Series Coilovers offer both performance and durability for enthusiasts seeking a serious suspension upgrade.

Key Features:
