Finally got some open road to bed the big brake kit in. Stopping power is definitely noticeable. Can't wait to get them 100% bedded in so I can really test them.

Pictures will be up tomorrow after I wash the car..... (just for you GTO) =)

Ah hah! I was right! Do I get a cookie??:laugh: Looking good Ed, but I really wish you would have gone with the black calipers as red is sooooo common and boring now.

You were right! We'll put it as I owe you a cookie.

I wanted the brakes to stick out and with two options, red and black... wasn't too hard of a decision.

The only other color I was thinking about was yellow, saw it on a Porsche and those looked really nice. Going to do a bbk? In blue?:rolleyes:

Looking good Brotha...

I'm so happy for you......

Thanks, I copied your wheels, I couldn't copy your brakes too....
 
To bring up an old thread, here are more details on my thoughts than you probably wanted to know.

Summary of my research (note that these are my opinions, you are
welcome to have your own):
Brembo - top notch R&D and brand recognition. Only made a front kit
for the FX and specifically designed to work with the rear OEM brakes
(per Brembo representative). Can purchase matching rear rotors from
R1 Concepts (888-712-6623 ask for Kit, these have to be custom
ordered. He knows what the GT rotors look like and will duplicate it
using Centric rotors) in California.

Buy these if you want top notch quality, brand recognition and a test
and proven brake kit as long as you can live with OEM rear brakes.
You are paying for it as the front kit retails at $3,795.

AP Racing - owned by Brembo, but two companies are run separate. I
was told by AP that the parts are made in England and shipped out to
the USA through it's exclusive distributor, Brake Pros, a division of
Stillen. Also, top notch quality and R&D. Here you are also paying
for this as retail is $2,799.75 (6 piston front) + $3,299.75 (4 piston
rear) = $6,099.50. I mention this setup as it's not recommended to
pair the 4 piston front (13" rotor) with the 4 piston rear (15" rotor)
by AP Racing.

Buy these if you are set on the best quality manufacturer that
provides front and rear brake kits made for the FX. It maintains the
correct front/rear bias. These also have a proven history and very
well know in Europe.

StopTech - Front only big brake kit with matching rear rotors. These
are perfect for street use and those that want increased stopping
power.

Buy these if you're set looking for a front only upgrade and also
looking at Brembo's and want to save $1,000+, get the StopTech.

Rotora - These are street bling to me. They make anything from a 6
piston to 12 piston front with a 4 piston rear. I personally think these
kits look the best and also good quality. I would have gotten the 12
piston front and 4 piston rear, but a specifically balanced 6/4 AP
Racing slightly appealed more to me.

JBT - I think same manufacturer as Rotora? Either way, same review
as Rotora's in my book. Pricing is similar too.

OEM FX50S/G37S Akebono - These are OEM – that pretty much explains it
to me. Cheapest brake upgrade, huge stopping power and availability
of aftermarket for rotors and pads, it's the best cost-effective brake
upgrade for the 2003-2008 FX35/FX45. Again thanks to Turbo for his
custom ball joint adapters and research to make this possible. Also
to offer this at cost – that's a stand-up kind of guy.

K-Sport/D2 - I have not seen any bad reviews on their brake kits and
only surprises of how well they work for the price. The other parts such
as suspension parts have several bad reviews, but none specific to the
brake kits. I personally will wait until they are more proven in the
marketplace before purchasing something as critical as a brake kit,
even though the price keeps tempting me every time I see it. K-Sport
and D2 use the same manufacturer.

Brand value (my personal thought as some don't add a value to this):
1) Brembo
2) AP Racing
3) Rotora
4) StopTech
5) JBT
6) K-Sport/D2

Bang for the buck front only (this is based of my personal quotes, not
retail – as Rookie said, who pays retail!):
1) OEM FX50S/G37S Akebono
2) K-Sport/D2
3) Rotora
4) JBT (these don’t sell as kits, you have to buy the lines separate
and more for cross drilled. Also less of a discount off retail)
5) StopTech
6) Brembo
7) AP Racing

Bang for the buck front and rear
1) OEM FX50S/G37S Akebono
2) K-Sport/D2
3) Rotora
4) JBT (these don’t sell as kits, you have to buy the lines separate
and more for cross drilled. Also less of a discount off retail)
7) AP Racing

Best front only kit if cost was not a consideration
1) Brembo
2) AP Racing
3) StopTech
4) Rotora
5) JBT
6) K-Sport

Best front and rear kit if cost was not a consideration
1) AP Racing
2) Rotora
3) JBT
4) K-Sport/D2

(all personal opinion and this is based off my personal price quotes)

Executive Summary:
Best bang for the buck front only upgrade:
OEM FX50S/G37S Akebono (~$900)

Best bang for the buck front and rear upgrade:
OEM FX50S/G37S Akebono (~$2,500)

Best front only upgrade if you don't take cost into consideration:
Brembo 4 Piston Front (note a 15" rotor) (retail = $3,750)

Best front and rear upgrade if you don't take cost into consideration:
AP Racing 6 Piston Front and 4 Piston Rear (retail = $2,799.75 +
$3,299.75 = $6,099.50)

Here are my other personal opinions:
Best looking front and rear setup:
Rotora 8 piston front, 4 piston rear (12 piston just looks too big,
even on the FX)

Best track kit (this is a complete guess):
AP Racing 6 piston front, 4 piston rear

Best street kit:
OEM FX50S/G37S Akebono 4 piston front, 2 piston rear

Best aftermarket availability of different rotors and pads:
OEM FX50S/G37S Akebono 4 piston front, 2 piston rear

Everyone has their own priorities on what's important to them so
hope this can help others make their own decision.

Thanks for all the feedback as everyone's comment did make a big
impact on which kit I purchased.

Also, after 1,000 miles, I was surprised at how much the pads squealed -- then I bedded the brakes again and burned off the glaze and, silent once again.
 
And you said my hub swap DIY was thorough!!!

I completely agree with most of your research and your findings. I remember sharing a lot of my research when you asked in my BBK thread. What the rep from Brembo told you is also what the rep from Stoptech told me. He pretty much told me there's no benefit from a rear upgrade, so both Brembo and Stoptech don't bother making one.

The reasons behind it have to do with a balanced front/rear design - which is also why (get ready for this) there is almost NO improvement in stopping power when doing ANY of these upgrades. Really. I challenge anybody with a BBK to go one on one with a stock FX, get up to the same speed and both of you go 100% on the brake pedal. Depending on road conditions, OEM might actually stop more quickly (in a shorter distance) sometimes. After all, they are designed to work with all the FX systems, including the ABS. Take a caliper too far out of the OEM performance range and ABS doesn't know what the hell is going on.

Here's the page in my BBK thread that I cut & paste the Stoptech buzzkill email:

///5445&page=2

What's the advantage then? Superior cooling and heat recovery. The larger rotor, cross drill holes plus internal vane and caliper design all help recovery and hold off fade for longer. I've posted about this before, with a detailed write up from Stoptech. It seems wrong. Well, not wrong, but counter intuitive or at least dissapointing. But really the engineers that designed the stock system did a good job. You may have more pistons in any particular aftermarket design, but take a look at the cross sectional areas of the pistons. Front OEM is a single HUGE piston. Add up the four pistons in my Stoptech and the total will be very close to the OEM piston contact area. Ever been able to find actual stopping data (performance numbers) on a manufacturer's website? Me neither.

Doing a rear kit would just be for looks - which is a pretty good reason for many of us in the modding community. In fact, if I had it to do over again, I might consider exactly what you did - AP Racing. I think you found the balance between quality and price, making it the value choice. And I like your color too - they look great with your wheels.
 
:rolleyes:

I agree, I did read that a magazine tested out several big brake kits on the 350z or G35 -- and StopTech was the only kit that actually shorten the stopping distance vs OEM. But it was clear that after multiple repeated braking, OEM was no match for big brake kits.
 
Great Write-up buddy....!!

I did stumble onto a little problem, but i honestly do not think my JBT BBK is to blame.
Thing is with the Gianelle's on i needed a 3 mm spacers to clear my piston .
Now i used sort of a universal spacers but with a hub centering wich is kinda great on such a small spacering.
These universal spacers have a outside diameter hub of 73.1 mm. The size my Gianelle's are with the centerring. So i can stick these in right away.
The inside diameter of the spacer is 67,1 mm also a standard centerring size.
So again i can stick the spacer into my wheel being centered and only have to use a centerring from 67,1 mm to our 66,1 mm hub diameter size.
This way i still be centered when only having a 3mm spacer on the car.

Downside is, as it is a universal system it it's like swiss chees with all the holes in it to make every pcd possible and still be centered well.
All these holes and the aluminium not being of the best quality there is the spacer was kinda weak.
Therefore couldn't handle the forces what it was given during braking.

JBT states that i need to use a 15mm spacer cause that is stronger. I understand there theory and also understand that there view is only toworths OEM wheel size.
For the OEM wheel you need 15mm to clear so that works fine, but with my aftermarket 10,5's i only can run 3-5 mm.
So this whole story depends on the type of wheel your ride.

Why am i telling you all this.....?? Cause you need to take this to mind before buying something and understand that when you get the issues i have you don't blame it on the manufacture. But check out these first as well.

I'm going to lett a spacers be cnc'nd at a metalshop closeby to get ride of this issue hopefully.
 
who in here has stoptech BBK i found a kit for $2500. Im just curious on how good they are since everyone seems to talk about akebono and rotora.
 
Jumbosrule is the only one I know of.

thanks for the response i just checked the website where i found the kit. The pic shows four rotors and calipers so i thought it was for all four but then when you really look at them you see its only for the front rotors. I guess im going to have to wait and see what to get the Akebono sounds good but would have to find someone here that i can trust to install them the other option is Rotora or simply just upgrade my rotors and pads.

Jumbosrule as StuLax18 said has the Stoptech kit.

Stoptech is top notch and is a very well known and respected in the G35/350Z crowd. A tuner magazine also tested it and it was actually the only kit that shortened stopping distance on the 350Z.

Akebono and Rotora offer front and rear, so aesthetically better than the Stoptech. But Stoptech does the job done and a rear kit is not necessary and you can get matching rear rotors.
 
AP Racing Update and Stoptech Trophy Brake Kit

Just wanted to update that I've had no issues with the AP Racing 6/4 big brake kit. Still going strong, no squeaks, rattles, fade, uneven wear of pads/rotors, shakes, shimmies, etc...

Pad and rotors have great life on them and exceeded my expectations. I thought I'd have to replace them sooner, but I still have looks like 2 years left is my best guess!

Also wanted to update that I found this Stoptech kit:
