This is a pair of slotted 13.9" 2 piece rotors for the 370Z using the 4 piston calipers. 2 piece design will save 12 POUNDS PER ROTOR while providing better cooling of the rotor due to the directional vane design and aluminum center hat. Kit includes safety wire drilled bolts. Rotors are fixed design, with floating rotors optional.

Price? Availability?

Per the website:
~MSRP - 1025USD
~Sale - 925USD

I can add to my cart, but no clue if they are shipping.

Wow,..that's expensive,..the Stillen AP 6 pot seems like a deal compared to this price..
but is an alternative for just rotors..

Im waiting for more vendors to come out with 2 peice designs so prices drop..

24 lbs of mass off the front, sign me up!:hello:

if you think this is expensive for that nice reduction of weight ,

hope you have deep pocket for the AP 6/4 with 2-pieces rotor
just those front replacement iron ring are 410$+- each
AND 275$ for the rear then you add the hardware 2x (65$) to mount them on your AP hat that you keep .

how do I know , well I made myself a nice christmas gift :)

Stock is 14" up front and 13.8" rear, and stock already has more rear brake bias than it should...why would they make the fronts 13.9"?

I have no idea. I was just searching and i came across this.

anymore info on these?

Some manufacturer needs to make a full floating 2 peice rotor kit for the akebono's!

omg getting these when I need new pads

do they offer drilled & slotted 2-piece?

Can I ask why?

I'm going to hold out, a great piece though, 24lbs off the front is a good savings

In my case I would like to save some weight on four corner's, and to have a better replacement for the stock rotor when they are ready to be changed.

EDIT: Using after market racing pads are shorting the life of the stock rotors. So a lighter, better quality, and slotted or J shape rotor will be a good replacement for me.

Thanks

J hook FTW

The reason why I asked is that a bolted 2-piece rotor assembly will usually achieve slightly more weight savings than a floating 2-piece rotor assembly. Race cars use floating rotors for several reasons, all of them related to extremely high temperatures, very high speeds and extreme cornering loads. On the street, floating rotors are helpful in certain applications, but not most of them.

For the Z, floating makes very little sense. Most people don't plan on maintaining their floating rotors by cleaning the bobbins every so often (which requires new attachment hardware). Also, they can cause some noise even with float springs in place, like the factory rotors on the R35 GT-R.

Would a high-quality 2-piece non-floating rotor assembly do the job? Certainly!

Would Z owners be willing to buy a proper fixed 2-piece version (not one using a cheesy low-cost rotor ring) over a more expensive "full-floating" version? Let me hear what you all have to say!

Yes, I would be interested in some fixed 2 piece rotors.

Yes, but from what I'm aware, you aren't selling one, correct?

Just gathering input from the crowd. There are some options in the works, but they probably won't all make it to production. Feedback is important at this stage before as final decisions need to be made soon.

i would be interested in this.... As long as I could use the stock caliphers.... if i wanted to...

I'm in.

I think we need to open a new thread (to get more attention)

AP - Chris_B, check your PM.

Got it -- replied!

Interesting posts in here, and interest in Akebono two piece rotors.

A quality front AND REAR two piece rotor kit will be available very soon... :tiphat:

Is there a website we can go to look at??

We have a solution that addresses all four (front and rear) 2 piece light weight rotors, heat treated, full floating, gas vented (slotted), directionally and rotationally pillar veined, with aircraft grade billlet aluminum rotor hats. Nothing but the best quality, the complete kit is also 100% made here by us in America, and rigorously street and track tested..

Let me know if anyone is interested....

:yum: pm pricing please, and weights

ive been interested, I really wanna upgrade my sport package rotors & pads. I priced out the stoptechs & I could get all 4 slotted rotors for alil over $400, if you could beat that price, Im all in. Plus I need a good brake pad recommendation for the street. PM me if you'd like...Thanks

Ah ... they're not going to be cheaper then Stoptech, the Stoptech rotors for $400 are 1-piece (no weight savings) not 2-piece like these.

I'm interested but is it just me or do those rear hats have the E-brake pads riding on aluminum? Thats like something the Russians would do (watch more Top Gear if you find anything wrong with this comment). Any possibility of fitting a steel sleeve in that bore?

so your saying the slotted stoptechs weigh the same as the heavy stock sport package rotors?

Well I guess you were right about it being alot more for the 2 piece slotted rotors, I found a third opition for slotted rotors: RacingBrake Two-Piece Rear Rotor Slotted Nissan 370Z Sport 2009 I really hope that is for 2 rotors, lol

Yes they weight exactly the same as stock, I had the front ones and compared the weights during installation.

You don't want a full floating 2-piece rotor anyway, just a maintainence headache with no benefit unless you spend 90% of your time at the track. Go with a fixed 2-piece like you found below. You won't save quite as much weight on the rears as the front as most use an iron hat in the rear to support the e-brake function.

We actually make our 2 piece rotors with and without the full floating option. Fixed rotor attachment points and full floating are both available. Although there is no real maintenance differences between the two and full floating rotors benefits both track and street driven cars.

would somone please explain the difference? I know what a floating caliper is, where it compresses with one piston, and pulls the opposite pad towards the rotor, but what the hell is a floating rotor? A rotor you can mount flip on the rotor hat if need be?

To state it simply.....The floating rotors are made and designed to be able to move (float) when the heat builds up in the rotor. As the heat builds up in the rotor the metal expands. A floating design will allow the rotor some room for expanding when hot and contracting back when cooled.
With a fixed or a solid mounted rotor, there is no room for the expanding and contracting movements that the rotor will go through during its heating up and cooling down cycles. Because of this a non-floating or fix mounted rotor is prone to warping much easier than a floating rotor. Floating rotors usually last a little longer as well because of this.

me too, both front and rear to save on unsprung mass. I personally have no use for racing calipers nor can I afford a BBK.

Wasn't Stillen planning on releasing a 2-piece rotor sometime?

PS: I hope the rear hat is made from aluminum. :tiphat:
