Benefits are discussed in threads on this forum and on IWSTi.com, the other leading WRX/STi forum. Just search for "ACPT driveshaft".
This is a race part so no warranty unless a problem develops right away (say thirty days). But so far ACPT has been good about correcting for the few problems that have developed.
