Relentless Autosports: 2 piece F&R rotor set for the Akebono brake kit
 

This group buy is for the Relentless Autosports front and rear, light weight 2 piece floating rotor kit for the G37s and the 370Zs equipped with the Akebono brake system.

At just about 19 lbs. each, these are the only light weight full floating rotors on the market for these brakes, and also the only two piece rotors available (at all) for the front and rear that are designed to work in conjunction with the 370Z/ G37s as well as other cars that have the front caliper adapters and are fitted with these popular Akebono brake kits.

These RA two piece rotors are made 100% here in the USA with the highest grade of materials available. No corners were cut when designing everything from the heat treated & tempered, balanced & stress relieved, gas vented (slotted), full floating, directionally & rotational pillar veined cast iron/ steel allow blend of the outer rotor, to the hard anodized, aircraft grade CNC machined aluminum center hats with aircraft grade full floating T-Locks & fasteners.

Sure, we could have cut many corners on material & design time to save a little money, but there should be no compromising when it comes to your brake kit. These rotors are the perfect complement to the Nissan equipped Akebono calipers.
Remember, brakes are one of the most significant and often overlooked high performance and safety modifications you can make to your car.



The RA two piece rotor system has SEVERAL advantages over any other rotors available today for this brake kit.

--Light weight rotors will shed SEVERAL pounds of detrimental un-sprung
and rotational weight mass, making the car MUCH more responsive.

--With the self centering, full floating rotor design, it lets the rotor expand
and contract due to heat in a uniformly manner. This way there is much less
probability of the rotors
warping, distorting, cracking, or failing due to the rotors movement during its heat cycles

--Rotors are not only gas vented for more even pad wear, but have rotational & directional
pillar veins that drastically reduce brake heat and brake fade up to 20%.
With less heat from the rotor traveling through the rotor hat and into the
hub bearings, it will increase your wheel bearing life

--You can maximize your long-term investment as the cost of replacing the
rotors when the time comes goes down significantly by only needing to
replace the outer friction surface instead of the whole rotor…. since the
center (hat) is reusable.

From what I understand, the stock rotor in the front weighs 30lbs each, so 11lbs off each tire is huge, that's like taking off 24" wheels and installing 18" rays. Good stuff.

I assumed that price is shipped, and tax is for those in CA?

$ 1,700 for 4 brake rotors, they look great & I'm sure they perform, but omg that is alot., lol

^exactly, I don't really track my car, but I would not mind paying half for these if they came with new pads, now that should be the group buy :tup:

These rotors are not for everyone and I understand that.
Please if you are not asking a real question with real interest in these rotors can we please refrain from negative comments, I'd really appreciate it.
We put A LOT of work, time, and money developing these rotors for people really wanting/ needing a quality two piece light weight solution for this brake kit. Here it is..
Believe it or not they are however, very conservative and competitively priced. Just check the prices on any other two piece rotor (let alone a full floating two pieced rotor) of this size. Quality two piece rotors have always been a premium and in this price range if not higher. These rotors are very expensive to make and I assure you there is little profit margin at this price. Plus there is no other two piece rotor solution in the world for the Akebono brake kit. Other companies have been promising these two piece rotors for several months and even years now... and still nobody else has developed a front and rear two piece, not to mention a full floating two piece rotor. It has taken the only other companies who have tried, months and even years to even come up with just the front.... and they still don't have a rear two piece solution.
Doing any checking around at all will show you that these rotors are priced right if not low for what they are and the quality and materials they are made of. These are not any China knock off's of anything, there are 100% designed and made here in the USA. That is very rare and not cheap these days.

:tiphat:
amazing product and under 2k is a great deal! Most people pay up to 2500$ on rims to save less weight then theses offer. Since Ive decided to put F/I on hold till fall and focus on brakes and suspension you'll see me on this list!

I agree. This is a great deal. I will be looking for you when I change out my brake pads..... I have a ways to go however...

Wow those look amazing!

I have the Akebono Kit on my 2006 350Z, and I love it, just the stoptech rotors I have are SOOOO heavy. This would be an awesome alternative, but just the price is way out of my allowance. I paid almost the same price for my full (front and rear) akebono complete kit.

I would definitely consider these if the price was right. But until then (or when there are other options available) I will stick with my stoptech slotted rotors. :(

Will these rotors work ONLY with Akebono calipers and w/e else comes with the Akebono setup ? We couldn't purchase Stoptech/Rotora/AP/Brembo or w/e calipers and mate then with the rotors ?

These are OE size fit rotors, so you can only use aftermarket calipers if they are designed to work with OEM Sport rotors for the 370z. Ie. OE rotor fit, OE Caliper fit = works. RA, am I right in assuming the rear rotors are thicker than stock, and come with a shim to fatten up your rear calipers, or am I wrong? (if so, the OE fit calipers you could buy from AP/Brembo/so on wouldn't be fat enough to fit the rear rotor) HOWEVER, if there is interest, I'm sure RA would make aftermarket calipers as well to fit these

if their rear rotors are thicker, a shim won't do anything. There is only a finite amount of space between both sides of the akebono caliper with pads installed. the only solution with a thicker rotor is thinner pads.

Sorry, I am not too sure what your exact question here is?.... This RA front and rear 2 piece rotor kit is designed precisely for, and fits as an alternative to the VERY heavy OEM rotors that this Akebono brake kit comes with.

Sorry, I am not too clear exactly what you are asking here either, but...
I am not sure of any other caliper option that these rotors will work with, but I would bet that the only ones that they would work properly with are the ones I have specifically designed them to work with, and that is the OEM Akebono calipers that come as an option on the G37s, 370Zs, the FX50, etc.

^^ Correct, for the most part :)

Correct.....but, there actually ended up being a lot more to it than that, I explained most of that to you in our phone conversation a while back. The (patent pending) rear caliper spacer and seal, and everything necessary to fit these much lighter, better heat vented, and slightly thicker rotors to your Akebono caliper equipped car comes with the kit.

LOL, thanks for the vote of confidence there buddy, but it was tough and ambitious enough for me to do all this development for these rotors here for this kit..... I am in no way looking into manufacturing our own calipers here any time in the near future, or even at all. This was taxing and exhausting enough to take on.... for now at least.

This is true, but Equinox is referring to our craftily designed and perfectly CNC formed caliper shim/spacer (and seals) that slightly spaces the two halves of the rear caliper apart perfectly... just enough to allow a much needed thicker, better ventilated 2 piece rear rotor to fit.

Unfortunately I have learned the hard way that this business is full of idea steelers, copy-cats, sheit talkers, and even back stabbers :shakes head:....
Needless to say, I have a lot of company & personal time and money (and favors) invested into this awesome two piece rotor design and am very proud of what we have come up with. It really took some real innovation to design and create this rotor kit, and to make it work with the Akebono calipers and improve over the stock rotors as much as they do.
With all that said, I actually was not wanting to say too much about the design and what it took to make the rear two piece rotor work with the caliper in here just yet in fear of a few potential copy-cat companies stealing the design and idea. I mean, I am sure there are probably at least a couple frustrated companies looking at this right now scratching their head and saying "why didn't we do that"? etc. I mean, honestly if you search around other forums you will see it has taken a few companies almost two years figuring out how to make the front 2 piece rotor and they still haven't figured out how to make the rear two piece work! Some companies have been promising that the front and rear two piece rotors have been coming for almost two years now. Honestly, I understand first hand now what they were up against. These were NOT an easy task.
I am proud of the solution we have. It couldn't work better.


Not necessarily... ;) I wouldn't bet on that :tiphat:
