Flatout GR40R Rally-Ready Coilovers for 2022–2025 Subaru WRX

The Flatout GR40R is the evolution of the GR40 coilover system, engineered for rally, rallycross, and competitive motorsport use. Designed for drivers who demand consistent damping performance under extreme conditions, the GR40R adds external reservoirs to all four shocks, increasing oil capacity, improving heat dissipation, and preventing fade during long stages or back-to-back sessions.

Whether tackling gravel rally stages, tight rallycross courses, or endurance motorsport events, the GR40R delivers rally-strength performance with unmatched durability and tunability.

Key Features

• 0–2” Adjustable Ride Height → Fine-tune stance and geometry for rally and motorsport conditions.

• Inverted Shock Design → Maximum strength and rigidity for harsh impacts.

• Bypass Piston Valving → Smooth compliance over small chatter, firm control over large jumps and hits.

• 1-Way Rebound Adjustment → Easy tuning for surface-specific performance.
