RZ Brake Upgrade
Anyone have track experience with upgrading to the '99 spec (RZ) rotors/calipers at all 4 corners vs. one of the aftermarket front "big brake" set-ups? The cost from Mazda Comp appears to be a little lower, it's a straightforward bolt-on, you don't need to change the master cylinder or (necessarily) put in a proportioning valve. The total weights would obviously be a little higher, but if the main advantage of larger rotors on the track is heat dissipation, I would think the larger mass of iron would do a better job of that than an aluminum hat/iron rotor combo. Plus you get the street-type dust seals so you don't have to rebuild your calipers every year. I see a lot of talk about different aftermarket packages, but little about this option. What am I missing here?

It is a good upgrade. SleepR1 has the full RZ setup and several others use the RZ rears.
