Using the IAG AOS Pitch Mount Bracket is quite straightforward. First, locate the passenger - side strut tower and the center firewall above the transmission pitch mount on your Subaru WRX, STI, or Forester XT. Remove the standard mounting bracket of your IAG AOS kit. Then, use the included M6x12mm socket head cap screws to attach the 2 - piece billet aluminum bracket to the new location. Make sure all the screws are tightened properly. As for maintenance, regularly check the bracket for any signs of loosening or damage. If you notice any issues, tighten the screws or replace the bracket if necessary. Also, keep the bracket clean to prevent any corrosion. When installing, always ensure your vehicle is parked on a flat surface and the engine is off to avoid any safety hazards.
