Using these brake rotors is easy. Just install them in place of your old rotors in your Mitsubishi Lancer Evolution's braking system following the standard installation process. When installing, make sure all connections are tight. As for maintenance, regularly check the rotors for any signs of wear or damage, like cracks or excessive thinning. If you notice any issues, replace the rotors promptly. Also, keep the rotors clean to ensure their best performance. When driving, avoid sudden and extreme braking as much as possible, which can put extra stress on the rotors and shorten their lifespan.
