74 Duster 11.75 rotors

Steve Agrella said

I own two Mazda’s, one is a Mazda 6 Grand Touring the other is a Mazda 3, changed both cars to drilled and slotted rotors and green pads, the difference is night and day from the OEM pafs.
The reason that I did this on both cars was because of the stop and go traffic in California is a nightmare,.
Both cars were suffering from warped rotors from the heat, after the change which was maybe close to a year no more warped rotors and the cars stop on a dime.
The rotors I used were same as stock dia, the brake feel and the stopping power of the new setup really is quite amazing.

Oh no doubt the green stuff pads are better than OEM, they’re much better. They’re still an organic pad, that’s all. In general organic pads don’t hold up super well with higher brake temperatures, although I know the green stuff pads do better than most organics.

I’m well aware of traffic issues and stop and go use, I’m in California too. I run semi-metallic pads on my cars, they withstand higher brake temperatures better in my car experience. I ran drilled and slotted 11.75’s with semi-metallic pads on my Challenger for over 70k miles, it worked great even on the larger car. The semi-metallic pads do wear the rotors faster, but I still managed 70k with the same rotors and only one pad change. But the drilled and slotted rotors are really only necessary to cool the brakes faster, so if you’re not having heat fade issues they’re not really a necessity. They don’t really hurt anything either, at least not anything night and day compared to conventional rotors.
