Very nice looking items...noticed a difference immediately.
had these for about 20k miles, they have performed flawlessly. whether carbotech xp12 for track days or posiquiets for around town, they've held up.
I've done a lot of track days over the years and more recently Time Trials and actual racing. I've used several different types of rotors, from OEM to the $600ea. 2-piece DBA 5000 series. Most recently I've been using these, the Z1 rotors. When I received them I immediately noticed how much lighter they were even compared to the DBA's. I also noticed that that was largely due to less material making up the rotors disks. I was a then just slightly wary of their heat absorbing capability. Well, after several track weekends they are holding up great and appear to be, if anything, more warp resistant than anything I've used so far. Though some heat stress fractures are showing up -totally normal-, it's still minimal, indicating a good consistent density/alloy composition. I haven't had any hot spotting issues either. Obviously the discs themselves are replaceable, increasing the value long term. Switching between my track pads (Carbotech XP20s) and street pads (Stoptech Street Performance) has caused zero issues. Just let the race pads scrub off the transfer layer before swapping back. To sum it up: the cost/performance value of these seems to be practically unbeatable. It doesn't hurt that they also look pretty dang cool!
Recently installed these amazing rotors on my 08 G37s. I immediately felt the performance and weight difference. i highly recommend them to anyone. I currently have z1 SS brake lines, motul 600 brake fluid, akebono ultra-premium ceramic brake pads and brake master cylinder brace. Thank you Z1.
I love them!! i dont have a Z but it made a big differences on my 2016 maxima sr, gain back my loss HP went i did the big brake kit, went from 32 pound rotor to this light 19 pound rotos. This week i will do my rear.
Exceptional quality rotors. Definitely can tell the difference once installed and they look amazing on the car. 100% worth the price.
