Input needed from those with 2pc rotors

It just depends. I have heard a bunch or really good track rats go to oem or other compatible blanks and do well. I don't have any experience with z1 one piece up front but have a set of their 2 piece rotors that I have been tracked for a couple of years. They have performed as advertised. I did have some shutter the last time I ran with them a Chuckwalla Valley. It was with a new set of pads same as what you were running. I think that my experience was due to it being cold temps in the 40s and 50s and 3" brake ducts. Over cooling is not good with aggressive brake pads.

I would take your time and do the brake ducting first. I would also check out Stoptech rotors. I did their 1 piece on my wife's Audi s5 along with their street pads and they are as good as what I run on the Z. Their 2 piece rotor are a floating rotor and are slightly cheaper that Racing Brakes. They are also heavier than z1 but lighter than oem.

Over cooling is something I didn't even think of, but now that you mention it... When I was at Laguna in September and had no issues with any shutter, it was definitely warmer than it was November 1st. I don't know the exact temperature difference, but it was definitely colder. This has me thinking about finding a way to have adjustable vents to be able to tailor ducting to the cooling requirements of a particular track, like they do in F1. Would definitely take some learning but I'm very intrigued by the idea.

If I had not have blown my motor LOL, I was going to cover the inlet with painters tape.
