Using this Clutch Masters flywheel is straightforward. First, make sure your vehicle is turned off and on a stable surface. Check if the flywheel is the right fit for your Subaru WRX, BRZ, or FR - S. When installing, use the proper tools to ensure a secure fit. Since there's no grease or alignment tool included, you'll need to get those separately if needed. Remember, this is a clearance item, so it's non - returnable. For maintenance, regularly inspect the flywheel for any signs of wear or damage. Keep it clean from dirt and debris. If you notice any issues like unusual noises or vibrations, it's best to have it checked by a professional mechanic.
