Reduce that drivetrain "shudder" you feel during hard acceleration by installing a KEIN Pitch Stop Mount. Pretty much any modification you do to your WRX or STi dramatically increases engine torque. And while the factory Pitch Stop Mount is perfectly fine for OEM power levels, it most certainly was NOT designed to handle the 300+ lb-ft that your typical modified WRX or STi puts out. The Pitch Stop Mount is found under the factory top-mount intercooler (installation is simple) between the fire wall and the front end of the transmission. The pitch stop mount is designed to produce crisper gear shifts by preventing the front end of the transmission from pitching up or down, forward and back.
