Using your StopTech high carbon alloy blank brake rotor is easy. Just replace your old factory rotor with this one. Make sure to follow the standard installation procedures for your 2005 - 2017 Subaru STI. When using, avoid sudden and extreme braking as much as possible to prevent excessive wear. Also, don't drive in very wet or salty conditions for long periods to keep rust at bay. For maintenance, regularly check the rotor for any signs of cracking or excessive wear. If you notice any issues, replace the rotor promptly. This will help you get the most out of your brake rotor and ensure a safe driving experience.
