Kartboy Rear Subframe Inserts

Kartboy Rear Subframe inserts fit into the subframe voids found in the OEM rear diff crossmember bushings on your Subaru. These bushings reduce stress on the sub-frame and focus that energy on the suspension, therefore increasing suspension feedback This, in turn, also helps reduce rear suspension geometry change. The Kartboy Rear Subframe Inserts come hand made in the USA and anodized in black, delivering the high quality one would expect from Kartboy. Kartboy Rear Subframe inserts work with the following vehicles:

  • ‘08 – ‘14 Impreza GT, WRX, STI
