Relentless Autosports: GROUP BUY / 2 piece F&R rotors set for the Akebono brake kit

Scott @ RA

We actually just installed another one of our rotor kits yesterday on another car, a G35 this time. As most of you know, on the older G35's and 350Z's the front Akebono caliper needs an adapter bracket for them to fit..... We make that too. Here are some pics of the adapter we make and the install we did.....
Here is the adapter bracket we make that allows the front Akebono caliper to go on the 350/G35. It is aircraft billit aluminum, CNC machined and hard anodized ($299)


Here is the install on the G35

Thanks for clarifying Scott!

wow these rotors kick ***!

1) can you confirm that the OEM rotors weigh 30lbs (weight savings of 11lbs/corner)
2) I have heard floating 2-piece rotors can rattle and be noisy...do the RA rotors have this issue?

Scott @ RA

Sure, as long as you cover shipping we will ship them anywhere.


Yes, we have confirmed (and several others have confirmed) that the front OEM rotors weigh about 29+ lbs each. Our two piece fronts weigh in just at about 19 lbs each, for a weight savings of about 10 lbs each front or about 20 lbs of rotating un-sprung weight in just the front alone. Now, with our thicker rear rotor that is rotationally and directionally pillar veined for better heat dissipation and longer life is still about 3+ lbs lighter than the OEM rears.

And to answer the question..... Actually, these rotors are surprisingly more quiet than I anticipated. They do actually make a slight rattling noise when going over some very sharp bumps at slow speeds (like rail road tracks, cracks in concrete, etc.), but it isn't too bad at all compared to any other floating rotors I have seen. Once you know what the noise is and are used to it, most people hardly notice it all after too long. We have had them on a few cars now and everyone has said that they are very quiet and the rattling isn't too bad with street and track use. Another noticeable point is that the harder track/performance pads tend to always be more prone to break squeal, but so far on these rotors even they are very quiet. That wasn't necessarily our goal, but a cool added bonus, LOL

Scott @ RA

With a total of more than 26 lbs of ROTATING and UN-SPRUNG weight being shed with these RA rotors.... If you calculate the ratio of all that rotating weight at the brake rotor axis, It is about the equivalent of at least 200 lbs of static weight removed from your car.
Just another example of rotating weight, most 18-19" wheels are about a 10 to 1 ratio of rotating weight vs static weight difference.... So theoretically the rule of thumb has always been if you can shed only 3 lbs off of each wheel (by getting lighter wheels, etc) this would be like removing 120 lbs of (static) weight from your car. 3 lbs X4 wheels x 10= 120 lbs!!

So I assure you that anyone's car that uses these rotors vs the OEM ones... their car will speed up faster, slow down faster, corner faster, and flat out respond better just like if you removed 200 lbs of regular (static) weight from the car. Not to mention there would be less wear and tear on all the cars suspension, steering, and braking components, since it is making less work for the car to carry around, and right where the weight matters to the car the most.
Rotating weight savings has always been the most important and effective weight you can remove on your car.
Hell, I am sure some people in here can testify that when they went to a lighter wheel or even a lighter flywheel, their car felt more responsive, right? Same thing here. I mean most people can definitely notice their car is noticeably more responsive when they are by themselves in it compared to when they have the weight of a passenger, correct??

We did some tests a while ago at a race track where I would run a few consistent laps with a passenger (about 130 lbs) and then run the same laps back to back without the passenger, and then repeat the process again and again for consistency. The results were always almost 2 seconds faster consistently on a track that took about 1 min 19.2 seconds with the passenger and 1 min 17.4 seconds without that passenger. So I hope you see the example I am trying to demonstrate on the weight and its effect on your car.

definitely on my list, but not for the group buy, as its a little out of the budget right now with the body shop bill coming due.

Just finally noticed that this is for the Akebono brake kit.

I feel stupid for not noticing that.

Too bad that I don't have those. so no pretty rotors for me

Scott @ RA

^^^ No problem, we can ad the Akebono caliper set up to our rotor kit (for about another $1200) and presto............. problem solved..

Vegitto-kun

Haha.....I need to win the lottery but could you give me more information about the brake kits then?

Since I AM looking at different options since I will be tracking the car in the summer

Scott @ RA

If you are going to be tracking your car (besides seat time with a good driving instructor) the best mod you will ever be able to make for your car as for reliability, consistency, and safety would be the brakes.
There is a couple of other complete brake kits out there that would probably work for you on the track as well as these with our two piece rotors would, but I am very confident in saying that there is no better brake kit out there for these cars at the price you can get this whole Akebono calipers and our two piece set up for. For information on these rotors look at the first post, if you have any more questions about them that wasn't covered, feel free to ask.
Another plus to this kit that I haven't mentioned is that because of these calipers being OEM Nissan, the brake pressure proportioning is perfect. It is a very good front to rear bias feel. I can't say that same thing about most any other after market brake caliper for these cars.

With the proper pads and brake fluid, these new RA, light weight/ two piece brake rotors legitimately turn this OEM Akebono brake kit into a true, real competition/ track worthy brake kit.... and at a fraction of the price of any comparable complete brake kit out there available for these cars.

Man I would love to have a set of these on the car. By the way Scott, I wrote a little article about these on my website. Thanks for bringing awesome products to the community.

Scott @ RA

Thank you, I just saw your website, looks good....

Hearing encouraging and kind words like that really means a lot to me, I appreciate it.

Beautiful. Craftsmanship. Bravo!
