The stock engine mounts and transmission mounts are satisfactory for daily driving. One mount people generally overlook is the Pitch Stop Mount. The Pitch mount is located under the stock intercooler and looks like a dog bone. That mount connects from the firewall to the tranny case.
Vivid Racing knows that as you increase power, handling and driveability must correspond as well. Added stiffness will benefit the car in acceleration and deceleration. The Pitch Stop mount is a great place to start. For $59 we think this mount will be a good improvement for your WRX as it was for ours. This fits the 2002-2004 WRX and STI.
