Using these DBA 4000 Series T3 rotors is straightforward. Just replace your old rotors with these as they are a direct fit for your 2005 - 2006 Mitsubishi Lancer Evolution. When you first start using them, take it easy on the brakes for the first few miles to let the rotors and brake pads break in properly. This helps them work at their best. As for maintenance, regularly check the rotors for any signs of wear or damage. If you notice any strange noises or a change in braking performance, it's a good idea to have them inspected. Keep them clean and dry to prevent corrosion, and store them in a dry place when not in use. Also, follow the manufacturer's instructions for any specific maintenance steps.
