Megan Racing MR-CDK-E36-RS Spec-RS Series Coilover Damper Kit 32-Way Adjustable

The Megan Racing Spec-RS Series Coilover Damper Kit (MR-CDK-E36-RS) is a premium, track-capable suspension system engineered for performance enthusiasts. Featuring 32 levels of independent damper force adjustment with separate compression and rebound controls, this kit delivers a wide tuning range to match any driving style — from daily street driving to aggressive track use.

Unlike single-adjustment coilovers, the Spec-RS system separates compression and rebound adjustment for enhanced tuning precision. Compression is controlled via an external reservoir-mounted knob for easy access, while rebound is adjusted via a knob at the top of the damper. Use the guide below to dial in the right setting:

• Levels 1–8: Recommended for track use
• Levels 9–16: Recommended for mountain/aggressive street use
• Levels 17–32: Recommended for everyday street use

The coilover body features independent spring perch adjustment and full shock height adjustment, which are separate from spring pre-load. This retains full suspension stroke while allowing the vehicle to be corner-balanced — a critical advantage for precision alignment and suspension tuning.

Height adjustments are made using CNC-machined aluminum locking spring perches for accurate, repeatable results. The wide range of ride height adjustment allows aggressive lowering for track applications, reducing the vehicle's center of gravity for improved handling dynamics.

On strut-type suspension designs, the Spec-RS kit includes fully adjustable Pillow Ball upper mount camber plates at both front and rear to reduce suspension deflection and simplify camber tuning. Proper camber adjustment improves handling, vehicle predictability, and tire wear — whether on the street or the racetrack.

The Spec-RS dampers are constructed from durable steel with SAE-9254 Cold-Wound springs tested over 500,000 compression cycles with less than 5% deformation. A high-strength surface coating provides long-term corrosion resistance.

Key Features:

• 32 levels of independent rebound and compression adjustability
• External reservoir for dedicated compression adjustment
• Separate spring perch and shock length adjustment for full suspension stroke retention
• CNC-machined aluminum locking spring perches
• Front and rear Pillow Ball upper mounts with camber adjustment plates
• SAE-9254 Cold-Wound steel springs tested 500,000+ compression cycles
• Rubber dust covers included
• Steel front brackets / aluminum rear brackets
• All hardware included
• 1-year manufacturer defect warranty

Important Note: The Spec-RS system cannot be adjusted to stock ride height due to its coilover design. This kit is intended to lower the vehicle significantly. Does not fit 318ti Compact models.
