Under normal driving conditions, the drivetrain is constantly moving back and forth. This movement is absorbed by the OEM pitch stop brackets and have not caused any problems until 2015+ year models were released. This normal movement of the drivetrain and weaker OEM brackets lead to failures shown in the graphics below. These failures come in the form of OEM brackets tearing, welds breaking off of the firewall, and sometimes a combination of the two.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 Brace does exactly what its name implies, it reinforces the brackets that connect the pitch stop to the car. Even under normal driving conditions, the brackets flex (see the animated graphic below for an illustration of this). The PERRIN Pitch Stop Brace acts as a means of helping to prevent damage and possible failure to your pitch stop brackets.
Included in the PERRIN Pitch Stop Brace kit is a replacement stainless steel braided Teflon clutch line. Not only does this clean up your engine bay, but our unrestricted stainless steel braided clutch line provides a faster response, and more firm and consistent pedal feel.
An added benefit of the PERRIN Pitch Stop Brace is that it not only comes with an upgraded clutch line, but also braces the clutch master cylinder, reducing firewall flex when depressing the clutch pedal. This is most noticeable on cars with stiffer aftermarket clutches.
The PERRIN Pitch Stop Brace body is CNC machined from 6061 billet aluminum and a black anodized finish with vibrant, laser engraved PERRIN logos.
