Perhaps someone can help me locate a set of rear aero rotors. Both Dali and StopTech's website offer front rotors only. I would like to purchase a matching set of front and rear StopTech rotors for aesthetic balance. Has anyone been able to get the rears before?
StopTech AeroRotors - why no rears available?

Insufficient demand.
I've gone through many sets of front rotors on my NSX. HOW MANY, you ask? I'm on my 10th set. Some have cracked, while others developed unbearable shudder.
And how many sets of rear rotors have I had to replace? ZERO.
If you get slotted Stoptech rotors for the front, throw a set of slotted PowerSlot rotors on the rear, and no one will notice the difference.

Ken,
Out of curiosity - have you ever worn out front rotors before experiancing shutter or cracking? If so make/model and if you were actively tracking them at the time would be interesting to note.
As for the rears - have you had them evaluated for usefull life left?
Just wondering...

Nick is referring to the minimum thickness spec. As you use rotors, they wear down and get thinner. There is a spec in the service manual for a minimum thickness. When they reach that point, they should be replaced.
I have never reached this thickness on my front rotors. They have always needed replacing due to other reasons, not thickness.
I had my rear rotors checked at my last track event in the NSX, which was at NSXPO 2001, and the nice folks from Acura of Brookfield said they were still well within spec.
Thanks for asking, though; this is a good reminder to everyone that the rotor thickness should be checked from time to time.

Do the powerslot rotors have a black mounting center similar to the Stoptech Aero's black anondized hat? I looked at the picture on the Dal site and was ot able to tell.
Probably not as much as the time and money that people have spent on attending NSXPO (for which I also must accept credit and blame) and on subsequent track events after getting a taste there of what they're like.
Of course, this is time and money well spent.
No; the mounting center isn't coated, just bare metal. But at least the slotted face would match the slotted face of the Stoptech rotors (if you get the slotted version). And you have to look pretty darn close to check out the hats to compare...

I believe Project U (mew) makes front and rear slotted/drilled (don't remember which configuration, might even be both) rotors with floating hats for the '91-'96 NSXs, but they are extrememly expensive.

Ouch $1200 for a set of f&r rotors! Ken's suggestion would be right around half that price. Hmmm, that will be a tough decision : )

I'm in the market for a brake upgrade as well. Looking at the big-brakes, but i realy don't need that. Those Ferodo 2500's are very good with the stock sized discs.
The problem is that with a nice front upgrade, you still have those small discs on the back.
Those really look like mickey-mouse-brakes in those Advan's 18 inch............

I recently installed AeroRotors and wanted (but, as KS has pointed out, probably did not need) slotted rears. So I put on PowerSlots. The funny thing is that the slots point in the opposite direction than the fronts! Oh well. I am still happy with my choice and if anyone asks why the slots 'rotate' a different direction at each end I will tell them it is so I can brake while reversing as well as I can while going forward!
BTW, the AeroRotors work great on the track. I recently tried them on my local track - a 1.2 mile road course affectionately known as a 'brake burner'. Despite running in the advanced group, the AeroRotors worked beautifully with zero fade. I have taken off my dust shields and installed TechnoFreno pads and Motul 600 fluid.

Then maybe you should have put them on the opposite sides from how they are currently installed
NSX Maven's rotors are installed properly. The direction of the slots recommended by PowerSlot is the opposite of the direction of the slots recommended by StopTech.
Mich,
You're in luck! I have been talking with AP Racing about developing a kit for the NSX. They are in the process of doing one now. The problem for me, but good for you, is that it will require 18inch wheels. It should be ready at the end of November. It uses 350mm discs, with 6 piston calipers.
Kevin
Later, they may do a kit that fits smaller wheels.

"NSX Maven's rotors are installed properly. The direction of the slots recommended by PowerSlot is the opposite of the direction of the slots recommended by StopTech."
I am curious what science this recommendation is based on. Unless there is a major structural difference in the slots themselves, the powerslots should be fine installed in the same direction as the StopTech slots. Is this flawed logic?

I know that the StopTech AeroRotors have veins (vents) that are directional; they need to go in a certain direction to maximize cooling airflow. I have verified with them that the proper rotors were marked as left and right, even though the slots are in the reverse direction from other brands.
I think the vents on the PowerSlot rotors are conventional radial vents, so the only thing that is directional is the slots themselves. Why (what science) they are recommended in the direction they are, I have no idea.
