I'm pretty excited about this product. Do you know if the FFD BBK will have the rotors inboard 8mm more than stock, like the RB RX-8 BBK? If so, that'll allow me and all the other Fikse owners to run this BBK on our cars.

if you do the above you will appreciate why RacingBrakes are going to be on my car and i am taking off the AP 13 inch setup...
as to availability... a fair question.
i am not affiliated w RB but i do stay in touch w them. AFAIK, they are on schedule to deliver an entire FD package... the schedule is april.
the package will include approx 13 inch two piece rotors front, approx 12.7 inch rotors rear. specially sized front 4 piston RB calipers w mounting brackets and SS brakelines. the rear will use the OEM caliper w emergency brake and will relocate using a RB caliper bracket.
the package is designed to maintain the excellent OEM front to rear brake bias, and will use a special line of Hawk brakepads that work w the one of a kind rotor material.

from concept to actuality and on time...
the brown truck should roll up monday and deliver a box from RacingBrake. i believe it will be a complete rear corner big brake system. while it is a beta, i will be installing it ( 2 piece directional 12.7 rotor, custom caliper mounting bracket, my OEM caliper w E brake and the SS brakelines and pads) to check everything fitwise.
i have a set of OEM FD wheels, a set of SSR 17 inch wheels, a set of 18 inch Enkei V1s and my new 18 inch Enkei NTO3+Ms. i will check all for clearance and advise.
once all measured back in the box they go to RB. the next boxes will be a 4 corner complete set.
RB currently offers a nice red or a super gun metal grey, both w white lettering. decisions, decisions on the calipers.
it won't be long and we will have them on the track. i will be running no ABS but will be running the OEM proportioning valve so we will get a very good idea how they will work on YOUR car.

speaking personally, adjustability is all w re to going really fast on a road course. i held lap records at 6 of the 7 CenDiv SCCA tracks so i know...
not everyone wants/needs to set lap records but almost everyone is driving around w crappy OEM FD brakes. i will be installing a manual adj proportioning valve in my system but i want to evaluate the RB system w the OEM valving so as to provide proper feedback to RB. both RB and I want this system to be optimized as to balance.
out of the box.
bias radically changes w the amount of G-s pulled under braking. if you run stickier tires you can pull more G-s. the more G-s you pull the more weight shifts onto the front brakes.
not everyone is going to be pulling 145 looking into turn 5 at Road America. but everyone can use better brakes.
there is alot of confusion as to what the proportioning valve really does. it doesn't create the longitudinal brake balance. it takes the properly engineered OEM balance and continues this balance even as the G-s mount due to pushing on the pedal harder.
once we have optimized the OEM setup i will add additional rear braking effort into my system by going to higher coefficient pads in the rear and add an adj proportioning valve.
i run 53% rear weight and can use more rear braking effort...

the just popped into my mailbox (May) issue of Dsport features an NSX on the cover. if you check pages 66 and 72 you will see RacingBrakes on it...
i received a rear rotor and caliper mounting bracket monday. very nice.
i fitted 18s on it and measured 1.25 and 1.1 inches of clearance between the wheel and caliper. the wheels were Enkei V1 (10 inch) and Enkei NTO+3M (10.5).
i fitted a 17 and found .55 inches. (SSR 17 X 10)
i am working on the OEM 16 to determine if it will fit. i have filed part of the outer ribs on the rear caliper and will advise as to whether i think the amount of metal needed to be removed might compromise the rigidity.
RB is on schedule and looking good.

At Laguna this Monday there were a gaggle of NSX'es, most of them supercharged with about 400-450 crank HP. Two of them had the Racing Brake rear setup with the stock caliper on an elongated bracket. They said they were very satisfied with the performance. I didn't get to drive their cars so I can't say anything firsthand, but they were pleased with their setup.
On another note, I toasted a set of HP+ pads at the track. I've got a set of full race pads on the way for next week at Infineon, but I'm sure that the next problem I'll have is boiling the fluid.
So Howard, this whole Racing Brake thing can't happen quickly enough.

it is about that time of year.... as the snow melts in the northern parts of the country track cars are getting back on the asphalt down south. as this happens i expect a number of accounts from racers running RacingBrakes emerging product line. RX7 specific reviews should start in April as the RB system debuts.
here is a review from Dan Mu... straight from the track running a 3300 pound 350Z.... as posted in Freshalloy.com
here's Dan.
I'm like literally kicking myself for not having done this sooner.
Despite the best laid intentions, the FA Project 350Z always lacked in one crucial area that all 350Z and its related platforms lacked. Brakes. I don't care if you have the track edition with the fancy Brembo brakes; the system was never designed for serious track use. And don't get me started on the replacement cost, even the non-Brembo brakes cost in excess of $100 a rotor and at least $50 per axle on just the OE replacement pads. And at the rate that I'm chewing through pads and rotors, I can easily spend over $1,000 in a year just on brake replacement cost.
Darn it, now you got me started on the brakes. Quite frankly, I was never comfortable with the 350Z on the track due to the constant brake issues. More often than not, I would experience brake fade half way through the session and have to really take it easy and let everyone pass or pull in the pits to let the system cool off. It's embarrassing when old BMW E30 318ises with less than 130 HP is passing the 350Z with more than 300 horses on tap, with wider, stickier tires and better suspension.
Upgrading pads and rotors only got me so far. I knew I had to have something that can effectively manage and control the heat while providing me with consistent brake torque that matches what this car is capable of. Part of the reason why I've gone two plus years without looking at a serious big brake solution was cost, another part was no vendor wanted to help. Luckily for us, RacingBrake stepped up and realized the value of the Nissan/Infiniti market. With the escalating Brembo replacement costs and rapid growth of the 350Z/G35 market, RacingBrake has applied some of their groundbreaking technology with innovative solutions to help this particular segment of the market.
RacingBrake has provided several performance upgrades to suite your particular budget and need. First up is their OE rotor replacement for Brembo and non-Brembo solutions. With decades of knowledge behind them and advanced metallurgy techniques, RacingBrake has come up with a rotor solution that is more durable than your OE cast iron rotors while providing a performance boost with a lighter slotted or drilled rotors. Not only are their rotor solution more durable, it also act as a better heat-sink due to the intricate directional vanes built inside the rotors to accelerate air flow through the rotors. You should see significant brake fade resistance and warp resistance by just upgrading to their rotor solutions. And the biggest benefit is that their OE rotor replacement is often times more affordable than purchasing OE rotors. Save $$$ and improve performance? Sign me up.
I was also looking for an effective way to increase the brake torque and performance by using a larger rotor. A larger rotor means better heat dissipation and also more leverage by the brake calipers to slow the car down. That and a 11" rotor behind a 19" rim just looks pathetic. Again, RacingBrake has an innovative solution here. They have designed and built a larger and lighter rotor in conjunction with a re-designed caliper bracket that moves the OE caliper out, in effect providing a brake upgrade without the cost and inconvenience of replacing the calipers. The end result is a more aesthetic looking wheel-well with improved stopping power and a 2 lbs per corner drop in un-sprung weight. This effectively allows the re-located caliper to increase brake torque without the penalty of rotational mass being moved further away from the center. Considering that it cost me over $500 to replace the first set of brakes that I chewed through after 1.5 day of track driving and 3,000 street miles, the cost to "upgrade" the rear brakes from RacingBrake is virtually free if you need to replace rotors and pads. The OE caliper upgrade kit essentially gives you a 13.1" big brake for Ľ the cost of a big brake kit.
Most importantly, I wanted stopping power that is capable of harnessing the 300+ HP the FA Project 350Z is laying on the ground and the tremendous grip the Bridgestone tires provides. I want a brake system that can take full advantage of all the work that I've put into the FA Project 350Z, be able to brake from 110+ mph down to 40mph at full threshold braking repeatedly and still function at the top of its game and provide the consistent feel at 5 minutes into a session AND at 30+ minutes into a session. Well, believe it or not, RacingBrake also provided me that ultimate braking performance in their 4 piston, 13.1" floating disc kit. Here again, RacingBrake has applied their patented technology in creating a center mounted floating disc, which allows air to flow in from either direction, in conjunction with their advance cooling vane design and superb heat-treated metallurgy. The result is a system that is 4-5 lbs lighter than the OE caliper setup with larger all-around rotors and an innovative open slot design that combines all the benefits of slotted rotors and drilled rotors without any of its drawbacks. Best of all, I can swap out the Hawk HPS street pads to Hawk DTC-60 track pads in less than 30 minutes. I just need to remove wheel, withdraw the two pad guide pins, and pull the pads up. No more fumbling with the caliper guide pins and getting all dirty changing pads.
The most impressive part is how well the system performed on the track. For the first time since I started working on and tracking the 350Z I was able to push the car to its limits without having that fear and doubt in the back of my mind…Will the brakes work the next time I approach turn 1? Time and time again I decided to punish these brakes more than I should, and I tried braking harder and deeper before a turn, and time and time again the RacingBrake system just shrugs off my attempt and give me that confident performance that I've been missing since I started driving this 350Z. At the end of the day I was nearly brought to tears, when at the last session of the day in searing 110+ degree heat, the TIRES gave out before my brakes did. The front pushed and the ABS kicked in on these tremendously racing compound tires that I have.
Personally, I am grateful for RacingBrake for stepping up and providing me a set of brake system that works as well as advertised, but I think the overall product line that they offer and the quality and excellence of the product, to perform as they're advertised at such a competitive price, is the best value they bring to the market. If you have a 350Z or G35, with immediate need for upgrade or replacement parts, take a look at what RacingBrake offers first.

Hi, been following this thread with interest but I’d be grateful if a couple of questions could be answered.
I take it that option 1, 2 piece discs front and rear are now available? (There seems to be only fronts on the RB website?)
If they are available, have they been fitted and tried out by anyone and if so what were the first impressions?
I apologise if I’ve missed something but it seems the interest is now in the BBK (Option 2) rather than option 1.
Thanks

I've read through most of the posts in this thread, and I am very pleased with all the info provided. I was planning on upgrading my calipers to the RZ, 99 spec, Spirit R whatevers. Anyway, is there any plan in the future to have rotors that will work with these calipers? If the answer is no, then would it make more sense to stick with the stock calipers and upgrade the rotors only?

I just spoke to one of the techs at Racing Brake, he told me that the upcoming front BBK for the FD will utilize their new lower-profile calipers. I explained to him my fitment issues with the Fikse FM5s and other BBK's on the market, and arranged to bring my FD by their shop for fitment when the kit is in the final stages of development, being that they're pretty local to me

We have been asked about the status of this RX7 brake project, and we are aiming to have both the front and rear kits available for test around 3rd week of April.
Please understand that we only estimate but can’t guarantee the date of availability until they are fully tested, especially this project involves specific caliper piston sizing, rear bracket design and tooling, specific rear big rotor rings etc. We even tool up the brake pads in different racing compounds for stock and upgrade calipers.
We have taken extra efforts in developing these BBK after knowing your demand and expectation. Almost every single component of the BBK is specially considered and designed for a brake system that would meet RX7 racing enthusiasts' requirement. They are far more dedicated and comprehensive than Stoptech or AP's standard front only BBK which involved only the design of caliper adapters.
We would appreciate your patience and hope when these kits are released you will find that the time we are allowed (less than 5 months, starting from last December) is justifiable and the wait is worthwhile.
Thank you for your interest.

Can't wait until the results from this BBK are released.
Warren- I assume these should have no problem with fade on a 2950lbs (includes driver) with about 600rwhp using race pads? (see sig)
Hoosiers Road race compound: 285/30/18 front, 335/30/18 rear

here's a heads up as to the initial test of the RB Brake system:
it will be done at Blackhawk Farms racetrack. i could do it at Road America but Blackhawk is to brakes as this weeks NASCAR race (Martinsville) is to brakes.
it eats them alive.
Road America with it's 3 long straights is much easier on brakes as Blackhawk is 1.8 miles. BHF is short and you are always on the brakes.
i make 525 rwhp modestly tuned so there's plenty of kinetic energy to bring to a halt. i also know how to work the track w over 5500 race miles under my belt and lots of wins and track records.
i will not be using race tires. my car is multipurpose. no roll cage. no fuel cell. i do run Enkei 18 X 9.5 fr and 10.5 rear w Toyo ts1s. i will work the camber settings and tire pressure so the brakes will get a workout. we will be measuring rotor temps etc.
i will be very interested in the OEM brake bias and the new RB system... i run no ABS and i have retained the OEM proportioning valve so my experience will parallel your experience.
once tested i plan to remove the OEM proportioning valve and add an adj valve.

i just heard from RacingBrake and while they are up to their ears in trying to get the new Corvette and BMW M3 systems out they continue to on general schedule for the car that WE care about.
and the news is EXCITING as to RX7 specs....
the front rotor is 332 X 32.... that is 1.26 inches thick on my calculator!
my AP Alcon rotors are only 1.15.
when you consider that the massive front rotor is made of higher carbon content alloy, has greater airflow due to the center mount and convergent directional interior air vanes it all adds up to being superior to any brakes ever bolted on to the FD.
i also really like the brand new 4 piston front caliper. it looks like there was considerable effort to combine strength and light weight. very slick.
i will be starting to look for the UPS truck next week. the front calipers might be the following week.
hang in there everyone, our cars are about 14 years old and can wait a few more weeks.
it was only a few months ago when i approached RB and we are now very close to a new 4 wheel brake system that IMO, will be superior to anything ever offered.
for the first time our brakes will be on par w our world class suspension.
a deadly track combo... especially when mixed w 400+ rwhp
thanks Warren and RB.

and thank you Howard for working on all of this with them 
I can say without a doubt that my decision not to purchase a BBK up to this point will reap huge rewards and i'll certainly be in the first group of people trying to get a full setup from them
