Upgrade handling precision, ride control, and performance capability with the Megan Racing Spec-RS Series Coilover Suspension System, engineered specifically for the Acura ILX (2016+) and Honda Civic Si Sedan and Coupe (2014–2015). Designed for drivers who demand maximum adjustability and motorsport-level damping performance, the Spec-RS system delivers a refined balance between aggressive street driving and track-ready handling.

This suspension system features 32 levels of independent compression and rebound adjustment, allowing precise tuning to suit driving style, road conditions, and alignment goals. Compression damping is adjusted via external reservoirs, while rebound damping is controlled at the top of each shock for quick and accurate changes.

Ride height is fully adjustable independently of spring preload through CNC-machined locking spring perches and adjustable shock body length. This design maintains full suspension stroke at any ride height and allows proper corner balancing and aggressive alignment setups without sacrificing damper travel or ride quality.

For strut-type suspension applications, the Spec-RS system includes pillow-ball upper mounts with integrated camber plates, providing precise camber adjustment to improve turn-in response, steering feedback, and tire wear. Built using high-strength steel dampers and SAE-9254 cold-wound springs tested beyond 500,000 compression cycles, this kit delivers exceptional durability and consistent performance.

Key Features:

• Independent Compression & Rebound Adjustment: 32-step tuning with separate controls for maximum precision.
• External Reservoirs: Allows fine compression tuning and improved damping performance.
• Top-Mounted Rebound Adjustment: Quick, tool-free access for easy tuning.
• Independent Ride Height Adjustment: Shock length adjusts separately from spring preload to retain full stroke.
• Pillow-Ball Upper Mounts: Reduces suspension deflection and improves steering response.
• Adjustable Camber Plates: Enables precise alignment tuning for street and track use.
• CNC-Machined Locking Perches: Ensures smooth, accurate, and secure ride-height adjustment.
• High-Strength Construction: Steel dampers with SAE-9254 cold-wound springs for long-term reliability.
• Spring Rate Flexibility: Dampers tolerate ±2 kgf/mm spring rate changes for custom setups.
