Using these Faction Fab F - Spec Brake Pads is straightforward. Just install them following the standard brake pad installation process for your Subaru STI (2004 - 2017) or EVO (2003 - 2015). When you're driving, you'll notice the great pedal feel and consistent braking. For auto - x or light track use, the pads can handle high - stress situations well, but remember not to push them beyond their 1300ºF maximum operating temperature. As for maintenance, check the pads regularly for wear. If you notice excessive noise or a change in braking performance, it might be time to replace them. In cold weather, the pre - scorched compound helps the pads work better right away, but still give them a gentle warm - up before hard braking. Also, keep the calipers clean to ensure the precision - cut backing plates fit well and the pads work smoothly.
