OK.

Thanks

EDIT: one last question. $250 for all four outer ring and hardware?

LOL I wish. No, that is each. Compared to any other outer rotor price of other companies, that is very cheap, not to mention much higher quality. ;)

Nice.

honstly I have the money but it's been saved for a Diff cooler. I'll see what i can do.

Thanks.

I really want my set of the RA rotors.

BUMP!

he, really? arnt cars always girls..? i guess you can "ride" whatever you want though....

jk. gl on the rotors!

My two girls are in my shop/garage - a 1959 Triumph TR3A and a 1970 Triumph TR6. They are hard to ride at my age. The Z is like a bud.

ahh i gotcha!

be sure to do a write up on those rotors!

BUMP...... Two more weeks left in this group buy...... Only 2 more weeks to get this up and going to 5 or more people......

I really want to get a set of these rotors. The REALLY inovative approach to using these rotors with the sport Akebono calipers is great. I'm sure everyone who might be interested is looking for some kind of a review. Well, if I can get a set I will provide it. Maybe it is about the cost? Good stuff isn't cheap - ever. Hopefully some of the knowledgable 370Z owners might offer their opinions.

Still hoping someone out there wants in on the group buy. I really believe the Akebono calipers are plenty good for track and street when mated with good floating rotors, brake pads and the right brake fluid. The AP rotors are designed so you can change pads without the bedding process, so have pads for the street and pads for the track.

I'm a little shocked and disappointed... all this discussion going on for the last year or two (all over the forums) about everyone wanting/ needing a quality, light weight, two piece rotor option for the Akebono brakes and this is all the reaction I am getting??......

I guess once somebody (ME) stepped up and spend the time, effort, and money to develop these high quality, light weight rotors you really end up seeing who is all talk and who is willing to follow through.,,,,

Anyways, I hope people will see the quality and workmanship as well as the awesome benefit these rotors offer.....





(time is running out on this opportunity to get these at this price)

I think these look awesome but i've also got to stop spending, need new jeans and shirts more than car mods this summer :(

I think many people did not realize the price for a good quality 2-piece rotor that fits the stock BBK.

Scott,
You have an awesome product and I am sorry for the slow launch. Its probably partly the economy.

I know for myself though, the body shop cost more than I expected, the IRS bill was MUCH higher than I expected this year, the trial coilovers I bought are winding up costing be double install and corner balancing because one failed driving out of the shop, and I am in the middle of a self imposed 3 month ban on new business so I can have a little break.

You have a highly specialized product, which very few of us on here can take advantage of. I will get a set as soon as I can afford them, but I am afraid you have overestimated your target customer base.

I understand that, thanks

Thanks and that is possibly true, although all's it takes is any research at all and anyone could easily see the price range of a two piece rotors of this similar size and quality. I have seen far inferior rotors go for more money than these ones. :ugh:


Thanks, I appreciate the input and the compliment..... but probably a majority of my frustration comes from all the hoards of G35 and 350Z people who have converted their brakes to these Akebono (G37s, 370Zs) brake kits.... For almost two years (and several hundred posts/ threads) there has been this big ordeal made on many forums about the cons of the extremely heavy OEM rotors and how a lot of people siad they need a light weight solution.... Well... I guess nobody wants/ needs the solution that bad..... LOL Jeeezz :shakes head:




Anyways... ^^ Thanks for the nice responses guys, I do appreciate the input.......

Maybe for now we will just convert this group buy into an introductory offer (with a little modification) instead.... Maybe in a while when/if there is enough interest I will start another group buy on these......

I was wondering based on cost:

Is it more beneficial to piece together:

Stock Calipers
Upgraded Brake Pads
2-Piece Floating Rotors (Color Option cost excluded)
SS Brake-lines

Or to just buy a complete BBK?

(Not including the cost of labor)

Perhaps people are seeing the math doesn't add up for making a build themselves vs. buying a whole kit? Or does that say something about the stock calipers that even with new rotors/pads/lines they don't compare to aftermarket ones?

This is my dilemma at the moment...

Thats a good point there... I have already thought about this.

A) This rotor upgrade really benefits the people who already have the OEM Akebono brake kit on their cars, as all they have to buy is our RA two piece rotors (pads and lines optional) and you would have a true big brake kit at just a fraction of the cost for a complete aftermarket BBK.

B) Even purchasing through us the complete OEM Akebono brake kit ..calipers, pads, lines, etc (excluding the OEM rotors) and combining them with our RA two piece rotors, you will still be at about $3000 complete. I have seen what is available as far as a complete big brake kit for these cars in THAT price range in the aftermarket... It is not pretty... LOL

Plus the benefit of having the perfect front vs rear proportioning that goes along with hydraulically matched OEM calipers/ master cylinder is a big plus over a sub standard after market BBK.

The quality of the Akebono calipers are surprisingly better than a lot of the aftermarket brake kit calipers out there, especially in the same price range.

I KNOW you would be VERY hard pressed to find ANY two piece, light weight, FULL FLOATING, brake rotor of any make that matches the quality of our RA rotors, that I will bet on.

Im thinking about getting a set for my 370. Taking 22 lb of of the front of the car would be great. I just put the volk t 37's with mickey thompson drag radials on and took 5.5 lbs of each back tire (305 35 18 ) drag radials. To take another 3 lbs of the back would be great. You can feel the differnce with the weight reduction now. 8.5 lbs would make a big difference.
Do they come in the fixed postion or are they only made in the "floating " design.

Please PM me.

thanks

I think an introductory price would be a great idea. What we really need is for one of the "really" hardcore guys to purchase a set and give us some honest feedback on the product, maybe an install DIY, and their driving impressions. I don't buy anything anymore without reading a review.

Yes the weight difference is night and day when it comes to responsiveness.

Yes, we do offer a fixed/ solid mount design as well as the full floating....

PM sent....

rotor weight (f/r)
 

^^ I'm pretty sure all these questions are answered in the first couple posts, please read it again carefully for your answers ... Here you go anyways....


Both front and rear rotor hats are made of 7074 Aircraft grade billet aluminum, then is hard anodized

Yes, it is and works great

The front is 14" OD, 8" ID The rear is 13.8" OD with a 8.378 ID

Sure, if that is what you want

The rotors are attached to the hats with aircraft grade stainless steel alen bolts, T-Locks, and locking fasteners

No need for wire tieing

Well first off we are dealing with rotating & unspring weight here, not just unsprung and not just rotating. The ratio is approximately 3 to 1 for unsprung weight vs static weight and approximately 10 to 1 rotating weight, like I stated.
Most 18-19+ wheels depending on where the mass is on the wheel (moment of ratio), is about 10 to 1 (as a rule of thumb) static weight vs rotating wheel weight. That rule of thumb of 10 to 1 has been used by racers for decades. Since these rotors do not carry the same mass in the same area as a wheel does (moment of ratio/ inertia) but is further in twords the axis point, it is a close ratio estimate to say 8.9 to 1 or so.
Using this approximate ratio, it is safe to say that adding these light weight rotors as apposed to the stock Akebono's is roughly 26+ pounds lighter (static weight). Multiply that by the estimated 8.9 to 1 as that of static weight and you get about 231 pounds.... 26 lbs x 8.9 = 231.4 lbs that the car should/ will react lighter to acceleration, braking, and corner G loads.

That my friends is a sizable advantage, to say the least. ;)

A suggestion. Perhaps if you split the package up and let people purchase fronts only at 50-60% of the cost (whatever you deem appropriate) it might be more palatable. I'm not really interested in replacing my rears (especially not at that package price). But for half the price the benefits of replacing the fronts is very tempting.

No problem...... We can/will sell just the fronts. The pricing for the front pair of 2-piece floating rotors with all necessary hardware is $899 (the rears are actually more complicated and more expensive to make)

I want them badly but yeah finances arent good enough at the moment :(

I definitely understand that..... I am sure most of us are feeling the pain of a struggling economy. :shakes head:

Just curious, are you a vendor on myg37.com? just trying to get the word out since not many people over there even know these exist...

No, I am not a vendor on myG37 (or any Internet Brands owned forums). I try to avoid any greedy and corrupt forums that not only allow, but encourage ridiculous child-like drama and witch hunts.

But please feel free to spread the word and let people know that these rotors exist and are the best and ONLY front and rear light weight two piece rotor option available for the popular Akebono brake kits... Thanks

hey Scott. I have been trying and talking to the admins on Our VQ on your behalf. Matbe they will change their minds.

I think I love you, Scott. :P

LOL haha :tiphat: Thanks.

But why is that... should I be a little creep'd out or??? :ugh2:

Those IB boards bother me too. Most people don't even notice how... weird they are. Only reason I still visit my350z is the Detroit Z community.

Cool, well on that note, I am sure ANYONE who visits that retarded "my350z" forum can see just why I despise that forum... I mean I haven't had a membership on that forum in like 2-3 years and I'm still one of their biggest childish topics... Rumors, hearsay, lies, and corruptness rules that forum... :shakes head:

PM's answered

Scott of RA told me my 2 piece rotors are coming soon. Even though the group buy didn't go as expected he is honoring my order. I found out in conversation with him, he is very particular with what he ships out. My left side rotors were not as he wanted and they are being made again. I will let the forum know how the rotors turn out. As a blatant plug, he will still sell a set (front/rear) for the group buy price. Hoping to get his rotors on some Z's that will see a little track time.

^awesome news.

i think too many people have these brakes just for looks scott which is the problem right now. :p

any recommendations for good street/track pads to go with them? dedicated track pads?

I ran a few pad choices by Scott and used the info off of this forum. For street I'll be using Hawk HPS pads and for track days I'll be using Carbotech XP10 pads on the front and XP8 pads on the rear. Scott said it is a good choice.

Received my BC ER coilovers with Swift precision spings from BC Racing as ordered by Scott at Relentless Automotive today. The packing was excellent and they sure do look "purdy". Started reading the installation instruction manual and realized I need the help of an interepter. Can any of you tell me what "At this time you just need to use adjuster of easier use power. That will be fine." might mean? Seriously, the BC's are well made, but the proof is in the use. By the way, I went with 12k front and 10K rear on the springs, which should be a nice compromise for street and track.

Woady, I would have to agree with you on the fact that it seems that for the most part people did/ are buying the Akebono brake kits more for the looks, rather than the performance.

However, with the addition of these light weight two piece rotors (along with upgraded pads, lines, and fluid), we can and have turned these well proportioned Akebono brake calipers into a legit and track worthy big brake kit.

As for my recommendation on brake pads for street and track... I honestly have not tried a lot of different pads (extensively) as of yet.

The stock OEM pads are a very light duty pad and although they serve their purpose.... I would recommend a better/ harder street pad for use with our harder, heat treated rotors.
At this time, I can only vouch for the Hawk line of pads we have used thus far, on this brake kit. Although there is plenty of quality pad companies and choices that should be just fine.

So I can recommend the Hawk HPP for light to moderate track use and the Hawk HPS for daily driving. These have worked well so far.

What I am looking forward to..... In the near future (with the help of the automotive leader in custom brake pads) we hope to experiment more with a wider variety of custom compounds, friction materiel's, and heat ranges of pads and will actually be branding our own pads for a variety of different uses.

Glad you received your custom Relentless Autosports valved and spec'd BC Racing ER series coilovers that were custom valved to match the supplied Swift springs. :)
