Cusco Japan is the performance arm of the CUSCO brand, a Japanese motorsport specialist founded in 1968. With over five decades of engineering heritage, they design and manufacture suspension and chassis components—coilovers, sports springs, anti-roll bars, strut tower braces—and drivetrain upgrades like helical limited-slip differentials.

Their Street Zero II and Type RA coilover kits feature independent rebound and compression damping plus pillowball top mounts, giving drivers on-carriage adjustability for ride height and firmness. Cusco’s anti-roll bars and chassis braces stiffen the body to reduce flex, improving turn-in precision and mid-corner stability. Meanwhile, their helical-gear LSDs share torque smoothly between wheels, enhancing traction on corner exit.

Every Cusco part is CAD-designed, heat-treated, and built in Japan to JIS/JWL quality standards for direct-fit installation on popular platforms—Civic Type R, Integra, Toyota 86/GR 86, Subaru WRX STI, and more. Backed by decades of success in Super Taikyu, D1 Grand Prix, and domestic track series, Cusco Japan brings race-proven technology to the street, delivering sharper handling, chassis rigidity, and confident performance for enthusiasts at all levels.
