I'm pretty sure my rotors have lost their coating in the SC. I can hear what sounds like fast ticking coming directly from where they are so I'm assuming the coatings gone. Do i have to worry about this? The sound doesn't bother me at all because the cone filter sucking and the exhaust overpower it, but I'm just curious if i have to worry about this because I don't plan on fixing it. Not that I'm lazy or anything, I've just spent more money in repairs than the car itself (didn't know it was gonna happen) and I don't wanna fix it unless its necessary.
