Using this wheel stud kit is straightforward. First, make sure your vehicle is one of the compatible models, like Subaru WRX from 2002 - 2025, Subaru STI from 2004 - 2021, etc. Each pack contains 5 wheel studs, and you'll need one pack for each wheel, so get 4 packs for all the wheels of your vehicle. When installing, follow the specified hole sizes and drill bit sizes for your hub type (cast iron/steel or aluminum). As for maintenance, since these studs are cadmium - plated, they are quite durable. But it's still a good idea to regularly check for any signs of wear and tear, especially if you use your vehicle in racing conditions. Also, be aware of the California Prop 65 warning. When working on your vehicle, try to avoid breathing in exhaust, don't let the engine idle more than necessary, service it in a well - ventilated area, and either wear gloves or wash your hands frequently.
