Maximize handling precision, suspension control, and performance capability with the Megan Racing Spec-RS Series Coilover Suspension System, engineered specifically for the Nissan 350Z Coupe and Infiniti G35 chassis. Designed for aggressive street driving, track use, and competitive motorsports, the Spec-RS system delivers advanced adjustability, consistent damping performance, and durable construction for high-demand environments.

This coilover system features 32 levels of independent compression and rebound adjustment, allowing drivers to fine-tune suspension response with exceptional accuracy. Compression damping is controlled via external reservoirs for increased oil capacity and thermal stability, while rebound adjustment is conveniently located at the top of each damper. This dual-adjustment design offers significantly more tuning flexibility than conventional 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.

The Spec-RS system includes pillow-ball upper mounts to reduce suspension deflection and improve steering feedback. Constructed from high-strength steel dampers with SAE-9254 cold-wound springs tested beyond 500,000 compression cycles, this suspension system is built for durability, consistency, and repeatable performance under demanding driving conditions.

Key Features:

• Independent Compression & Rebound Adjustment: 32-step damping control with separate tuning for maximum precision.
• External Reservoirs: Increased oil capacity with independent compression adjustment.
• Top-Mounted Rebound Adjustment: Quick and accessible tuning without disassembly.
• Independent Ride Height Adjustment: Shock length adjusts separately from spring preload to retain full stroke.
• Pillow-Ball Upper Mounts: Improves steering response and reduces suspension deflection.
• Dual-Cylinder Damper Design: Enhances damping consistency and performance under load.
• High-Strength Construction: Steel front and rear brackets for durability and rigidity.
• Rear Extension Knobs Included: Simplifies rebound adjustment on rear dampers.
• Complete Hardware Kit Included: Ready for direct installation.
• Manufacturer Warranty: 1-year warranty against manufacturing defects.
