To this end, Subaru redesigned the Impreza's control systems to properly harness the performance benefits of the Sport Maxx RT. Chief to the changes is the Driver-Controlled Center Differential (DCCD) exclusive to the STi model. A rally modification designed to augment the Impreza's Symmetric AWD system, the DCCD manages the operation of both the limited-slip, planetary gear-type center differential and the electronically-controlled center limited-slip differential. The DCCD will have three settings to further assist the AWD in all road conditions.
Other competition-class modifications are also bundled into the 2015 WRX/WRX STi, such as bigger brakes, tuned suspension, and a stronger chassis. A dealership like Baldwin Subaru in Baton Rouge will always have your best interests at heart- especially when you want something that has been blooded in competitions.
