best rotors

Totally agree, Z1 2-piece rotors are totally garbage for track use. And I wish I knew "the false statements" before I gave them 3 chances.

I have some experience with Z1, DBA and Stoptech.
I wrapped 3 sets of Z1 2-piece in less than 5 track days.
DBA 5000 2-piece works slight better. But they still wrapped in about 5-6 track days.
The Stoptech OEM replacement rotors actually last the longest. I guess the extra weight helps the heat capacity. They last about 15-20 track days for me. And they are so cheap to replace.

Iammeowwwwww

I can attest to the stoptech rotors. I have the slotted front and rear, non cyro-treated. They last very well, however I do have a lot of ABS engagement that puts my brakes in ICE mode. I'm not sure if that's the rotor, pad combination, or some shitty ABS design.

That said, it's a shame that we can't really use the stoptech name anymore.. I'm pretty sure my front pads with them have been on back order about 4 months now. So I've looked at different pad options, and pretty soon I'll have to do the same for rotors.

I'm currently using Xp8 rear and xp10 front. I was debating between the paragon 2 piece and the Z1 2 piece, but after rading the thread so far, I think i'll forego the Z1 option. I've not heard of racebrake or Frozen before. I'm leaning towards paragon $1800 for all 4 compared to $2,200 with racebrake.
