Pitch Stop Mount by Perrin

Under hard acceleration, the drivetrain is being twisted front to back from front axle torque twist. To control this front to back twisting, Subaru created a pitch stop mount. The factory pitch stop is made of plastic with soft rubber bushings, allowing for a significant amount of movement under hard driving conditions, creating drivetrain slop and shudder. The PERRIN Pitch Stop mount controls the movement of the drivetrain in both on and off throttle driving giving the driver a more positive feel and literally putting more power to the wheels by eliminating lost energy.

The PERRIN Pitch Stop Mount's body is machined from 6061 billet aluminum and features a combination of 90a and 70a durometer bushings. The bushings are as stiff as possible without introducing excessive NVH. (noise vibration harshness).

It's dope just get it.

Chris Berry
Pitch stop

Works perfect

Christopher Lee Holt

Much needed beef... only a few items should have come from the factory beefier and this was one of them.

Brandon Bachert

This pitch stop is much better than the stock one. It’s crazy that there is a notable response difference.

Joshua Brazil
Looks cool and feels smooth

Easy install, looks great (only if it wasn’t covered by TMIC right after install), and an immediate noticeable difference in drivability. The pitch mount makes the car feel great under acceleration and deceleration and helps with slop that the WRX experiences in first and second gear. There is a slight drone that is added due to extra NVH but hardly noticeable. Also probably needs some more bracing like the pitch stop brace for extra added support. Great product and great feel.
