Product Details
The Cusco Sport R Coilovers for the 2015-2021 Subaru WRX STI (VAF) deliver race-grade monotube performance with pillow ball upper mounts, inverted front struts, and competition-specification damper valving. Aggressive 14 Kg/mm front and 16 Kg/mm rear spring rates with 24-level rebound control prepare the VAF for time attack and endurance racing.
The VAF STI's symmetrical AWD and EJ25T turbo make it a formidable track weapon when properly suspended. The Sport R's stiff spring rates control drivetrain mass during hard braking and corner exit, while pillow ball upper mounts eliminate rubber deflection for steering precision at the adhesion limit. Monotube construction resists fade through extended race sessions. For WRX STI owners who are building a dedicated competition car and need Cusco coilovers with zero-compromise race valving, the Sport R is the right foundation.
