Unleash the full handling potential of your Nissan 370Z Coupe with the Megan Racing Spec-RS Series Coilover Suspension System. Engineered for aggressive street driving, track use, and competitive motorsports, the Spec-RS system delivers maximum adjustability, precise damping control, and uncompromised suspension geometry for the Z34 chassis.

The Spec-RS coilovers feature 32 levels of independent compression and rebound adjustment, allowing drivers to fine-tune suspension response with exceptional precision. Compression damping is adjusted via external reservoirs, while rebound adjustment is conveniently located at the top of each damper. This dual-adjustment design offers significantly more tuning flexibility than traditional single-adjustment systems.

Ride height is adjusted independently of spring preload using CNC-machined locking spring perches and adjustable shock body length. This preserves full suspension stroke at all ride heights and allows accurate corner balancing and aggressive alignment setups without compromising damper travel.

For strut-type suspension applications, the Spec-RS system includes pillow-ball upper mounts with integrated camber plates, enabling precise camber adjustment to improve turn-in response, steering feel, and tire wear. Constructed from high-strength steel and equipped with SAE-9254 cold-wound springs tested beyond 500,000 compression cycles, this suspension system is built for durability, consistency, and high-performance use.

Key Features:

• Independent Compression & Rebound Adjustment: 32-step tuning with separate controls for maximum precision.
• External Reservoirs: Increased oil capacity and independent compression adjustment.
• Top-Mounted Rebound Adjustment: Quick and easy tuning access.
