New Products available at Tuning Developments is the full Perrin Performance product range starting with the hugely popular Perrin Performance uprated pitch stop brace for the EJ25 engine in the Subaru Impreza WRX & STI 1993-on, Subaru Legacy and Subaru Forester
Reduce drivetrain shudder under hard acceleration by installing a PERRIN Pitch Stop mount. Subarus with power and drivetrain upgrades will need PERRIN's more aggressive option.
WHAT DOES PITCH MOUNT DO
Under hard acceleration, the drivetrain is being twisted front to back from the front axle torque twist. To control this Subaru added a pitch stop mount. The OEM pitch stop is made from plastic with soft bushed added which allows significant movement under hard drive conditions.
WHY DO YOU NEED ONE?
The Perrin pitch stop mount controls the movement of the drivetrain in both on & off throttle driving, giving the driver a more positive feel and literally putting more power to the wheel by elimination lost energy.
The pitch stop mounts body is machined from 6061 billet alloy and features 90a & 70A durometer bushes. The bushes are as stiff as possible without excessively increasing NVH (noise, vibration, harshness)
