2-piece slotted rotor.

Scott @ RA

First of all, you are comparing what exists right now in the real world currently (our rotors), to something that does not even exist yet from GiroDosc for this application. Second of all, I'm not too sure but isn't this GiroDisc (maybe if you can get enough interest) possible group buy thing just about the front pair, and not all four like what we offer?

I am sure we probably have two completely different motivations here. I/we bit off this very time consuming and very expensive project for this community because I felt that this was something that was desperately needed. Unlike 99% of other companies (yes, including THM)..turning profit and making money is NOT my/our motivation at all here with these rotors. These rotors cost me much more time and money to design and produce than I will ever probably see much of a profit from, if any at all. I'm fairly sure that can't be said for GiroDisc, the people peddling GiroDisc or any other company or product for that matter..... and that's just fine, no harm in that.

I am just very proud of the fact that a way smaller company like ourselves can and have accomplished FIRST, what NO other brake manufacturer has still successfully been able to do. Other well known bigger brake manufacturers have been promising this G37 & 370Z Akebono brake community light weight two piece rotors for over two years now, and still only have the (fairly easy to make) front pair to show for.

As for superior material.... I have used a lot of my background and my families in racing with our vast resources to aid in this project. We have consulted with several racing industry brake rotor specialists, aerospace engineers, metallurgists, etc about the VERY best possible tried and true design in the casting of the outer rotor as well as the decision of what exotic blend of metals to use, and even what temperature and process we would use to have poured in the molds for casting.
There was NO costs or corners cut in the process of making these rotors. It might even border on overkill for most people. I feel if you are going to do something like this, do it once and the absolute best way you can. We did the whole design, machining, and assembly here in house, everything but the outer rotor casting, which we also control.
Sure, we could have made these quite a bit cheaper with still some success without all the added cost of all the processes and attentional to detail. I felt it was best to make these rotors to the best of our resources would allow.
Brakes are without a doubt the single most important thing on a race car or performance car for both a safety and a performance aspect. Brakes deserve to be made the best you can without any corners cut, no matter how tedious and small.

So when I see other companies jump on our bandwagon it pains me to see them use generic, one way fits all cost cutting methods, standard grey cast iron, non tempered, non stress relieved, and heat treated rotors, with some sort of cost saving universal right or left vented design, etc. I am not trying to single out GiroDisc or any company imparticular here, just a generalization. I also see a lot of loose term use of the phrase "floating rotor", but have yet to see a working, TRUE full floating hardware design like the T-Lock and groove design we use out there in the market either, for that matter.

So, yes, I will go as far as saying I have NO problem saying our Relentless Autosports two piece rotor (design & materials) is NOT inferior to anything out there on the market for brake rotors for this or any application. There is NOTHING better out there short of the $7-$10,000 exotic carbon, carbon/Kevlar, etc style rotors that could consider being superior.

In fact, if ever there was a true comparable solution that is even close to meeting or exceeding the particulars of these rotors we make, I would GLADLY stop making these things. These are not easy to make for us, they are not cheap at all to produce (especially in very small runs like we have to do). For what you are getting, our RA rotors are WAY BEYOND reasonably priced, period.

THMotorsports

Scott, I am glad to see that you are so passionate about your product. While I understand that your company may be the only ones who have produced a 2-piece floating rotor for the Z34, I believe we are all in this for the advancement of all products for the Z34. My group buy is for whatever I get more interest in, whether that be just fronts or all 4 corners. I see it as pointless in producing something for which there is no interest in.

My motivation is to deliver a 2-piece floating rotor to the market at a reasonable price that out performs everything else out there. I am making nothing off of this group buy, zero, zilch, nada. I take pride in bringing new products to the market and seeing them succeed. I am not the type of person who just sees dollars and cents. As well, I highly doubt that you are losing money in producing these. In today's economy, NO ONE is going to produce a product in which they lose money.

Out of curiosity, how many sets have you sold for the Z34? Additionally, how many other applications do you produce rotors for?

How is it your bandwagon? While I understand that you might have produced the first 2-piece rotor for this chassis, the concept has been around for a very long time.

Getting back to what I started with, I believe we are both here to see this chassis advance and develop some of the best parts possible for it and its owners.

Scott @ RA

Really??, so you DON'T work for THMotorsports, and you don't draw an income and/or pay your bills from working for this company??? I doubt that is true, but I could be mistaken. Please Nick, correct me if I am wrong and you don't get a paycheck for selling parts. (cause I don't make any money or my living off of doing this)

^^ Once again, you know not of which you speak.... I can assure you without a doubt I/we have lost money thus far in the implementation and developing of these rotors at this point. With all the time, and cost that went into the process, the material, casting, and machining costs.... UMM yeah. We would probably have to sell a couple dozen more sets of these rotors before a profit is ever seen,...... so yeah,

About 6 complete sets (front and rear) are complete and out there at this time. Some customers only bought fronts, some just rears, and some all four. These Akebono equipped Z34's are the only rotors we have produced thus far. Although, we are currently working on another application right now.


Sounds good. Good luck. See ya around. In the meantime, I am sure it was not your intention.... But can you please not insult me or our product (without having first hand knowledge or data and experience on our products or the products you are peddeling) by comparing any cheap, inferior, cast grey iron overseas made, mass produced rotor to our rotors. I'd appreciate it buddy.

THMotorsports

Don't get me wrong I do work for THM, but whether or not this is my primary income is irrelevant. Contrary to popular belief, we are unlike all the other vendors out there. I personally went to school (as well as the main other guys I work with) and we all do our own thing. All things automotive have been a hobby of our since we were young. We all met in college through automotive related hobbies and continue to be friends. I can assure you, THM is like no other company out there. Personally, I think its rather offensive that you try to call me out on a matter such as this.

If you have lost money, than I feel sorry for you. Honestly, there is no reason for someone to stick their head out there so far as to go into the red.

Never at any time did I insult you or your product. If you go back and review the messages, you will see that it was YOU that jumped down my throat. Never did I claim to have knowledge of your product beyond my understanding.

In all honesty, I feel as though you have taken the defensive and are trying to belittle our company (THM) and GiroDisc based upon your language. As I have stated several times before, the product GiroDisc offers is superior to anything else on the market. Your stand has become null and void, as well as rather offensive.

Scott, I would appreciate if you do not insult me, my company or girodisc for that matter. Your verbiage is rather offensive. And for you to take this stand on a public forum shows dis-taste. If you feel as though my claim is invalid, go ahead and read your last statement to me.

If you are happy with the product your company offers, than that is all that matters.

Scott @ RA

For the sake of all this getting out of hand, I will agree to disagree and drop all of this at this point. It is obvious that we both are not understanding each others tone the way we are both intending to portray ourselves..

Yes, I am passionate and am a bit sensitive when having our product compared to the likes of a product that I know FOR a FACT is NOT of equal or the same quality. I MEAN I KNOW this to be FACT, not just a random claim. It is ridiculous just how much I have learned about cast iron properties, cast metal characteristics, different blends, hardness ratings of combined material, etc.. Not to mention my very own aerospace engineering background. Remember, I have seen and used GiroDisc rotors, first hand as well as MANY other aftermarket rotor companies. So I AM speaking from experience and I AM POSITIVE of my claims here of being better designed, better made, and with better materials. I wouldn't argue like this or have taken offense otherwise. I know for a fact that there is no US based company or otherwise that use such a costly blend of metal for our outer rotors, as well as the temperature at which we pour our molds, heat treat them after cooling, etc. Or use a 7 series aircraft grade billet aluminum for the rotor hats. GiroDisc as well as most others use run of the mill cast grey iron outer rotors as well as standard T6 aluminum for their hats... there may be nothing wrong with that but it is an inferior material and process, I can assure you.

Now, I will leave it at that and I hope you understand where I am coming from.
Sorry for my part in it, but I for one have more pressing things to do then have a pointless argument on a message board/ forum.... I hope you do too.
Sorry for any misunderstanding on my part that may have happened.
I'm out

THMotorsports

Im sure you can tell from the frequency of my responses that I have more important things to do than bicker on the internet. Agree to disagree, done. If you feel like you need to contact me in the future about this, do not hesitate to email or call.

Thanks in advance,

Nick

Wilwood sells a ton rotors and hats that in a variety of mix and match sizes. I have not looked at the specs of the stockers in terms of rotor width and hat depth but more than likely they have parts avialable to make a set of two piece rotors with thier off the self stuff.

ZforMe

It'd be great if someone could figure out these measurements ( i wouldn't know where to start), and find the correct parts.
