AST Suspension RAC-M3008S Series Motorsport Coilovers - 5300 3-Way

The AST Suspension RAC-M3008S represents the pinnacle of motorsport suspension technology, engineered for serious track enthusiasts and professional racing teams demanding championship-level performance. This 5300 Series coilover system features true 3-way adjustability, allowing independent control of rebound, low-speed compression, and high-speed compression damping through external remote reservoirs.

Advanced Adjustability:

• Rebound adjustment with 12 distinct positions on the strut for precise control of damper extension
• High-speed compression adjustment with 12 positions to manage rapid, forceful impacts
• Low-speed compression adjustment with 14 positions to control gentle compression forces
• All adjusters operate completely independently for ultimate tuning flexibility
• External remote reservoirs provide additional oil capacity, improved heat dissipation, and increased travel

Professional-Grade Construction:

• Monotube coilover design on both front and rear dampers for superior response and consistency
• 44.5mm diameter inverted strut design engineered to handle extreme side loads and braking forces
• Aluminum cylinder construction with threaded body and factory mounting style
• Low-friction seals for responsive damping characteristics without aeration or foaming
• Spherical lower eye shock mounts and spherical upper shock mount assemblies
• Synthetic hydraulic fluid for consistent performance across temperature ranges
• Adjustable spring rates for customized setup

Complete Kit Includes:

• Front and rear monotube coilover dampers with external reservoirs
• Camber-adjustable front top mounts for enhanced geometry tuning (where applicable)
• Solid rear top mounts (where applicable)
• Precision-matched springs based on extensive development and testing

Built for the most demanding motorsport applications, the AST 5300 Series delivers the adjustability, durability, and performance characteristics required to reduce body roll, improve corner responsiveness, maintain optimal tire contact, and achieve faster lap times. The inverted strut design minimizes geometry changes under heavy cornering and braking loads, while the monotube construction ensures consistent damping throughout extended track sessions. Fully serviceable, rebuildable, and revalvable for long-term performance.
