Transform the handling, responsiveness, and overall driving dynamics of your Subaru Impreza WRX or WRX STi with the Megan Racing Spec-RS Series Coilover Suspension System. Designed for enthusiasts who demand maximum control and adjustability, this system delivers motorsport-level damping performance for aggressive street driving, track use, and competition environments.

The Spec-RS coilovers feature 32 levels of independent compression and rebound adjustment, allowing precise tuning of suspension behavior to match driving style, road conditions, and alignment goals. Compression damping is adjusted via external reservoirs, while rebound adjustment is located at the top of each damper for quick and accurate changes. This dual-adjustment setup offers significantly greater tuning flexibility than traditional single-adjustment coilovers.

Ride height adjustment is completely independent of spring preload thanks to CNC-machined locking spring perches and adjustable shock body length. This design preserves full suspension stroke at all ride heights 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, enabling precise camber tuning to improve turn-in response, handling predictability, and tire wear. Built from high-strength steel and paired with SAE-9254 cold-wound springs tested beyond 500,000 compression cycles, this suspension system is engineered for durability, consistency, and long-term performance.

Key Features:

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