Using this IAG AOS pitch mount bracket is straightforward. First, make sure your Subaru is the right model (2006 - 2007 WRX, 2004 - 2007 STI, or 2004 - 2008 Forester XT). Remove the standard mounting bracket from your IAG AOS kit. Then, use the provided M6x12mm socket head cap screws to attach the two - piece billet aluminum bracket to the appropriate spots on the center firewall above the transmission pitch mount. Next, install the AOS on the new bracket. As for maintenance, regularly check the screws to ensure they're tight. If you notice any signs of wear on the bracket, such as cracks or excessive corrosion, it's a good idea to replace it. When installing, be careful not to overtighten the screws, as this could damage the bracket or the mounting points on your car.
