While the GR40 delivers rally-strength performance with inverted dampers and precise valving, the GR40R takes it a step further with external reservoirs on all four shocks. These reservoirs significantly increase oil capacity, keeping the dampers cooler for longer and eliminating fade during the punishing heat and abuse of competition. Whether you’re charging through a gravel rally stage, tackling a tight rallycross course, or running back-to-back track sessions, the GR40R is engineered to maintain consistent damping performance when lesser systems give up. Key Features of the GR40R Coilovers External Reservoirs on All Four Shocks → More oil volume for cooler temps and fade-free endurance. 0–2” Adjustable Ride Height → Fine-tune stance and geometry for rally and motorsport conditions. Inverted Shock Design → Rally-proven strength and rigidity for harsh impacts. Bypass Piston Valving → Smooth compliance over small chatter with control on big hits. 1-Way Rebound Adjustment → Easy fine-tuning to match surface conditions. Rebuildable Construction → Serviceable and tunable for long-term racing use. Electroplated Shock Bodies → 7–10 years of corrosion resistance for dependable performance. Who Is the GR40R For? Rally Drivers → Competitors who need consistency over long stages where heat management is critical. Rallycross Racers → Drivers pushing through short but intense sessions that demand precision and fade-free damping. Motorsport Enthusiasts → Grassroots competitors and teams looking for pro-level suspension without stepping all the way to the GR50R. Builders \u0026amp; Tuners → Projects needing a balance of rally-strength durability and endurance upgrades. Customer Benefits Fade-free performance thanks to external reservoirs on every corner. Proven rally coilover strength with enhanced endurance for competition. Adjustable rebound for tuning suspension behavior to your driving style. Reliable, rebuildable design ready for season-after-season use. Better consistency and control than standard GR40 under motorsport conditions.\u003c\/p\u003e","brand":"Flatout Suspension","offers":[{"title":"Default Title","offer_id":47453012754622,"sku":"40R-0814WRX","price":4482.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/4299\/2830\/files\/image0_7__51671.jpg?v=1779325670"},{"product_id":"9802forester-gr40r","title":"98-02 Subaru Forester [GR40R]","description":"\u003cp\u003eFlatout Suspension GR40R – Heavy-Duty Coilover System with External Reservoirs The Flatout Suspension GR40R is built for rigs that carry more, go further, and push harder off-road.

While the GR40 delivers rally-strength performance with inverted dampers and precise valving, the GR40R takes it a step further with external reservoirs on all four shocks. These reservoirs significantly increase oil capacity, keeping the dampers cooler for longer and eliminating fade during the punishing heat and abuse of competition. Whether you’re charging through a gravel rally stage, tackling a tight rallycross course, or running back-to-back track sessions, the GR40R is engineered to maintain consistent damping performance when lesser systems give up. Key Features of the GR40R Coilovers External Reservoirs on All Four Shocks → More oil volume for cooler temps and fade-free endurance. 0–2” Adjustable Ride Height → Fine-tune stance and geometry for rally and motorsport conditions. Inverted Shock Design → Rally-proven strength and rigidity for harsh impacts. Bypass Piston Valving → Smooth compliance over small chatter with control on big hits. 1-Way Rebound Adjustment → Easy fine-tuning to match surface conditions. Rebuildable Construction → Serviceable and tunable for long-term racing use. Electroplated Shock Bodies → 7–10 years of corrosion resistance for dependable performance. Who Is the GR40R For? Rally Drivers → Competitors who need consistency over long stages where heat management is critical. Rallycross Racers → Drivers pushing through short but intense sessions that demand precision and fade-free damping. Motorsport Enthusiasts → Grassroots competitors and teams looking for pro-level suspension without stepping all the way to the GR50R. Builders \u0026amp; Tuners → Projects needing a balance of rally-strength durability and endurance upgrades. Customer Benefits Fade-free performance thanks to external reservoirs on every corner.
