Product Details
The Cusco Sport S Coilovers for the 2015-2021 Subaru WRX STI (VAF) deliver monotube performance with inverted front struts, pillow ball mounts, and 24 levels of rebound damping adjustment for street-and-track versatility. Equal 8 Kg/mm front and rear spring rates provide neutral handling balance across the symmetrical AWD system.
The VAF STI splits its life between daily driving and track days, and the Sport S is built for exactly that dual role. Monotube dampers with high-pressure nitrogen handle sustained track sessions where the EJ25T's heat output pushes twin-tube designs past their limits, while pillow ball upper mounts sharpen steering response and allow camber correction for aggressive alignments. For WRX STI owners who want Cusco coilovers that perform at HPDE events and still ride well on the commute, the Sport S delivers with 24 levels of adjustment to dial in both.
