The STI Flexible Support Subframe is designed as a stiffening part that connects the rear side cross member and the body. Compared to the standard rigid type, the rear side of the body is made more flexible by dividing the left and right sides via a rubber bush. STI's unique tuning of the power transmission from the front to the rear during steering operation and improved grounding of the four wheels on the road improves driving stability during cornering, giving the driver a quick yet straightforward steering feel. It provides a better ride comfort.

STI, Subaru Tecnica International, was founded on April 2, 1988 by Subaru (then Fuji Heavy Industries) to bring Subaru's motorsport work under one company, and is based in Mitaka, Tokyo. Its first public outing was a world speed endurance record run in the Legacy in 1989.
STI prepared Subaru's cars for the World Rally Championship with Prodrive, which made the Impreza WRX STI famous, and it races at the Nurburgring 24 Hours and in Super GT. Its road parts, developed alongside Subaru's own cars, include suspension, brakes, exhausts, chassis bracing, aero and interior parts for the WRX, Impreza, BRZ, Levorg, Forester and more.
