AST Suspension 5300 Series Coilovers - Mitsubishi Evo 7/8

The AST Suspension 5300 Series suspension for Mitsubishi Evo 7/8 provides a tunable damper system for drivers developing a setup around their vehicle, tires and intended use.

Rebound damping and separate high- and low-speed compression adjustments give three damping controls. Compression speed refers to damper shaft movement, not vehicle speed: slower shaft movement can accompany body motion, while faster movement can occur over sharp surface changes. Separate controls support more detailed setup work but should be adjusted methodically.

Key specifications

• Adjustable rebound damping.
• Separate high- and low-speed compression adjustments on remote reservoirs.
• Monotube damper construction.
• Rebuildable dampers.
• Ride-height adjustment on the supported configuration.
• Springs included in the listed suspension configuration.
• Manufacturer part number: RAC-M3006S.

Damper construction follows the suspension layout. Do not assume every unit is inverted or that every upper mount provides camber adjustment. Exact mount configuration and any application-specific installation requirements should be checked for this part number.

Installation and setup

Check the application, wheel clearance and suspension travel before selecting the final ride height. Establish alignment and, where appropriate, corner weights before tuning damping. Change one setting at a time and record the result so a useful baseline can be restored.

Remote reservoirs and hoses require secure mounting with clearance from heat sources, steering and suspension movement. Use the installation procedure and adjustment limits supplied for the exact kit.
