Looking for the ultimate foundation for your Subaru STI drivetrain conversion or suspension upgrade? This complete JDM 2008–2014 Subaru WRX STI front and rear subframe assembly includes many of the most sought-after factory performance components Subaru enthusiasts look for when building a serious street, track, rally, or engine swap project.

Available from J-Spec Auto Sports Inc., this complete STI suspension and drivetrain package comes removed from a genuine 2008–2014 Subaru WRX STI donor vehicle and includes the front and rear subframes, Brembo brake system, R180 limited-slip differential, R180 axles, hubs, control arms, and supporting suspension components.
