I'm betting a few heat cycles would destroy those rotors. I'm no metallurgist (sp?), but I believe titanium wouldn't fare well with repeated expansion and contraction... doesn't it tend to become brittle? I also wonder how well the pad would interface with the rotor surface.

You certainly don't see any race cars running these things, so that should tell us something.

Is it just me or its not the same brake kit..

Thanks Jim, I thought they were probably some other material.. I should of asked the owner about the brakes.. but he seemed so mighty that I just didn't want to bother..

 

I saw those brakes on a S2000 in one of the Super Street Mags awhile back, I may be wrong but they don't look like the can handle ANY time on the track

 

Those slotted cuts are nicely designed to allow the rotor to expand radially from heating without stressing the slots to the point of cracking. Does it work? Dunno, but it's an interesting idea.

damnit at closer evaluation you right they are not the same kit but another different and intresting rotor pad combonation ...........

 

They are Titanium rotors, it was Vette magazine, and ZMI claims a 30 lb. savings in unsprung weight (obviously dependent on kit) over standard rotors. Their 15.0" rotors weigh 5.3 lbs. according to their web site.

"ZMI uses aerospace titanium for the rotor because of its strength, heat dispersion properties and light weight. In order to build the ultimate rotor we didn't stop there. A patented design is then water-jetted into the titanium creating a slotted blade rotor. This design allows the titanium to expand in such a way that it turbulates the air creating an "active cooling" effect to speed up heat dissipation and prevent brake fade. Also, after the rotor is cut, a patented "chemical etching" process takes place which hardens the titanium and helps increase titanium's coefficient of friction to the other materials i.e. your brake pads to ensure maximum stopping power."

"Turbulate" isn't a verb, (or even a word, for that matter) but it sounds good, I suppose.

PN 12-200F-00-R73 - FD 12.0" x 0.35" rotors/hats and calipers - $3,595.00
PN 13-200F-00-R73 - FD 13.0" x 0.35" rotors/hats and calipers - $3,725.00

Here is an example of it too. Just thought you guys might like to see it.

Give me a break. Marketing adspeak at work...
