I use race pads (Cobalt Spec VR/VX) on the track, and street pads (Cobalt GT Sport) for street and autocross. When I get new pads, I bed them in, which I understand is for the purpose of depositing pad material on the rotors, which makes braking more efficient, and lengthens the life of the pads.

I assume that I need to do the same thing with new rotors. Assuming that is correct, do I also need to bed both the used street pads and the used race pads with the new rotors, since I don't change rotors for the track?

Thanks.

I always thought that the pads should be bedded-in against the rotors in which they will be used against? Therefore, if I got new pads and rotors, I'd install them both before bedding them in. This is actually good timing, as I will be installing new pads and rotors on the WRX once they arrive this week.

Also, what if you're installing a BBK?
