Hello,
I have a 2014 ExSport at 45000 miles and am preparing to do the first brake service. I've read that most, or all, of the performance rotors are based on Chinese slugs that companies mill, drill and slot. Also, that I should stick with a rotor that was manufactured with OE specifications and that the best performance upgrade you can do is buy better pads. I'm sure there are numerous opinions, but is there any merit to what I read?
