I put my order in for them this week. Life time warranty on the Titanium rotors. About 70 pounds of weight savings. Track ready with a pad change. A bit pricey but awesome nonetheless.

I put the order in for my ZMI kit on Friday.
I went with the 14 inch front 13 inch rear.
The kit is made to order and will take 2 weeks to build. I will be out of town untill the 18th of Oct. I will have the brakes on that night and will post Pics soon after.
sjs said:Hmmm... their PDF shows only one number for the NSX, a 13 inch set apparently for the front. So what did you order? Also, are you sure they will clear your wheels?
I'll be interested in what you think of them but I'm a bit nervous about a solid .25 inch thick rotor. As much as I hate unsprung weight, rotor mass helps dissipate heat. If their approach to cooling really works, then great. A day at the track should tell.
I'm also curious about their use Titanium. That's a very popular claim today but nobody ever says how much Titanium their product contains. Is that the weight savings or is it just light because it's thin? Are you stuck always running their pads or are they a common size so you can try different ones?
Well I hope they turn out to be what you're looking for but at first glance I'm not sure how much is flash vs. substance.
AJKS said:Titanium is not that much lighter than cast iron. From what Mike at ZMI told me they are solid Titanium.
...Titanium being able to handle the heat you can make a thin rotor.
AJKS said:Look at the price chart. You will see a 14 inch upgrade for 200 bucks. They are .35 thick not .25. I asked all the questions you asked and I would not have orderd them unless they will work. They will clear stock 16/17's. Titanium is not that much lighter than cast iron. From what Mike at ZMI told me they are solid Titanium. So yes, the weight savings is because the brakes are thin. The thing is you cant have a .35 inch thick cast rotor. So because of Titanium being able to handle the heat you can make a thin rotor. If you call Mike at ZMI he will cut you a deal. Tell him John told you to call. You will see when it comes to the bottom line (Front/Rear e-barke set up all SS brake lines) you will see the price is just a bit more than what else is out there now. Also take into account the fact that the rotors cary a life time warranty. The pads by the way are off the shelf parts (not sure what from).

AJKS said:...So just out of curiosity why all the negitave crap about these new brakes?...
sjs said:Speaking only for myself...
Actually, I thought my comments were quite reserved. I'm not saying they are crap, but whenever a new product comes along, especially from an unknown (to me) supplier, I start by questioning everything that sounds even faintly off. I think it is unwise not to challenge their claims. Sure, I could pick up the phone but I'll get their standard sales answers just like you did. Have you ever know a sales person to tell it straight and without bias? So the first step is to toss it around here on the forums to see what others may know and better prepare hard questions.
As for why my initial reaction is to be suspicious:
~ I know enough about brakes to realize that these deviate from accepted norms about what works. Maybe they're just the first to make this approach work for cars, or maybe they are pretenders, but I'm not sending in my $$ based on cool looks and claims from some website and neither should you.
~ As noted earlier, Titanium is a very popular "X" material for marketing these days whether or not it has any real benefit. Having that as a primary claim to fame is a red flag of possible hype without substance.
~ These brakes are clearly designed to catch the eye of the NOPI and yes SEMA crowd, of which I most certainly not a part. While there may be plenty of good hardcore performance vendors at those shows they are outnumbered by the ones selling flashy junk that has nothing to do with real performance despite the claims in their brochures. That description fits the vast majority of wheels sold today for example. The bakes may be as good as they say, but they absolutely scream poseur. An old cynic like me tends to assume that anything that looks that way is for the cruising crowd not the serious performance junkies. But then I pause and make an effort towards an open mind.![]()
Calling is not going to make them track proven.AJKS said:...do me a favor and call them on monday and ask some hard questions, do some digin. Maybe you will find out something I did not. It would be nice to see the ZMI brakes track and street proven for NSX's.
So, the IRL system looks much the same? How does it differ as far as thickness? How does the intermetallic coating differ, if any? What other materials, if any, comprise the titanium compound?zmibrakes said:As far as the look, it is purely function.
How so? Was an NSX used in testing? How is the porportioning achieved?From zmibrakes.com
