Using these Faction Fab brake rotors is straightforward. Just install them on your 2002 - 2005 Subaru WRX rear wheels as you would with regular rotors. Make sure to follow the vehicle's installation manual for the best results. When it comes to driving, you'll notice an immediate improvement in braking performance, whether you're on the street or having a bit of fun. As for maintenance, keep an eye on the rotors for any signs of excessive wear. Since they have a black E - coating for corrosion resistance, they're pretty durable, but if you live in a place with a lot of salt on the roads in winter, give them a good clean after driving in those conditions. Also, don't forget to check the brake pads regularly as well, as they work together with the rotors to keep you safe on the road.
