I have 2 piece Stop Tech aero rotors in the front. Plain surface (had to special order them). Still on the OEM rotors rear.

When I changed the rotors, there were little plain surfaced options available on the market. The OEM front Brembo rotors retail at 450$ each at Nissan and you can’t get them anywhere else. So the Stoptech were cheaper at ~600$, plus the replacement outer rotors are 160$ each. It was a simple decision.

I need new rear rotors now and I’m not sure what I’ll get. Maybe slotted 1 piece Brembo, simply because of the price. I try to avoid slots and drilling as much as possible though. Undecided still…

 

The price of plain Brembo rotors have come down thanks to Centric. They can be had for around $65 a rotor for the fronts and less for the rears.

 

ATE Customer Service replied that the shelf life is 2 to 3 years.
I'll check for a date on the can and I think I will still use it. The most recent one will go in the Z, the other in the winter car as it never has had a brake fluid flush.
