This looks like an awesome kit, especially for the price. I just wish there was some feedback here from people who have actually experienced these brakes.

 

The 350z link above has a bit of info, but it'd be nice to see the brake temps after some hard lapping. The AZ kit is 6 piston vs. fastbrakes 4 piston, so for $45 extra I'd go with AZ, everything else being equal. I wonder why AZ's rotor slots go both directions - also in the first picture at http://www.arizonazcar.com/350zbrakes.html, shouldn't the rotor vents be the other way to bite into the wind??

 

I have the Arizona Z car front 6 piston. Tracked it once, no fade, not sure about the brake temps though.

The rotor on the Arizona Z car is a standard Wilwood slotted rotor. Part number 160-3584, 160-3585. http://www.wilwood.com/Products/002-...2-GT/index.asp. The vents only go one way, as shown in http://www.wilwood.com/Products/002-...002-GT/dwg.gif One rotor is for the left, the other is for the right side. It is also one of the thickest rotors at 1.38" for maximum heat dissapation.

Somebody tried explaining to me why the slots go both ways, but I'm not sure as to the validity. On normal slotted rotors that go one way; when the slot hits the rotor you can feel it hit the rotor. So when you brake, you can feel it or even hear it when it hits each slot. It looks like on the wilwood rotor, as the pad leaves on slot there is a smooth transistion to the next slot on the other end of the pad. It kind of made sense to me when you look at the slot positions, but it could be bs.

 

Firefox, how is your pedal feel vs. stock? How much pad did you go through front vs. rear on your track day? Did your antiskid kick in front or rear?

 

I'm comparing this to the braking system on an automatic (non-brembo). Keep in mind that I only have a front kit. I have some hawk pads on the rears.

I'm no expert, but I always felt that the stock system was a little too "grippy" with very slight engagement of the brakes. The Wilwoods feel less grippy, but you can somewhat control it better just by stepping on the pedal more. The final stopping power seems much better than stock non-Brembo. I guess the feeling is fairly consistent from the beginning of the track session to the end. Where the stock system would start getting greasy the longer you get into a session. Braking is really smooth, whether it is light braking or really hard braking.

The pads seem to last quite a long time, they are real thick to begin with. The last time I went, I used street pads. I have another set that I got from summitracing.com, but I haven't had a need to change them yet. I will probably get another set of racing pads for the track. It takes about 10 minutes to change the pads out, real easy.

The only think I wanted to mention is that the rotors did finally warp after a year's worth of use. I had to get them machined, you just need to find a machine shop that will turn slotted rotors. They ended up taking off 0.08" off of each rotor, so my rotor is only about 1.30" thick now.

 

More mail from Dave at ArizonaZ Cars:


It will work if you plumb it in,
I just read some of the posts on G35driver.com....... here's some more info that you might pass along:
We make all our own rotor centers and brackets ( 6061 T-6 for the material) in house on CNC equipment. we use only the highest
quality bolts (grade 8 or better) , I have the brakelines made for me specifically for my kits.
We are a factory direct stocking wharehouse for Wilwood. All of this allows us to offer a better kit
at a better price than the competition!
Dave

Dave,

All I need is for the parking brake to work. If it does work, it will pass inspection.

Dave,

OK, I’m impressed. I suppose your Wilwood BBK would be great for street use also? I’m sold. Since my G35 is my daily driver and I must pass State Inspection, the parking brake would be included.

 

This is a copy of my post in the other thread concerning the same issue:

I spoke with dave yesterday at AZ Z car. After reading all the posts, it does look like a very good deal. He is a direct vendor for wilwood, he gets the calipers from them, the rest of the kit he builds at his own shop per wilwood specifications, therefore he is able to sell them cheaper than anyone else. One thing I was dissapointed with, he only gets black calipers. So if you want red ones, get yourself some break paint. They are 13.06" rotors, not the 13.6" someone mentioned earlier and 1.38" thick. I got a quote on a all-4-corners kit, 13" rotors all around $2246 plus $65 shipping. That's almost the price of the Brembo GT front kit for our cars. Now I did not ask if that was a 6 piston or 4 piston front caliper. The kits, as the site states, come with all the gear needed, stell braided brake lines, nuts n bolts, mounting brackets, brake pads, etc. Doesn't seem like a bad deal at all, but the dilemma I have is if it will fit my sedan and not run into ma sha1's problem. I spoke with dave about it and he said i would need about an inch and a half clearance from the face of the rotor and where the wheel meet. To me it looks like i have just over an inch, so i may need a spacer. I asked if i could return the item if i run into fitment issues and he promptly said NO. That right there does not sound to good to me. He should be able to offer a full refund. Take it for what it's worth and shop at your own convenience.

 

FireFox, can you give us some info on how your parking brake is working?

 

The parking break is my major worry with ArizonaZCar! Dave says he will supply a hydraulic break. I do believe that means the Infiniti parking break lever is not what is used to engage the parking break? If this is true, I probably won't be able to pass State Inspection here in Texas. I may need to go with the more expensive alternative for the rear brakes, the Wilwoods with the parking brake drum incorporated. That was $1850 from another vendor.

 

Thanks very much for the many posts and questions about the brake kit we offer for G35-350Z. I have been making racing brake kits for Nissan sports cars for well over 20 years and have sold thousands of kits in 2 dozen countries worldwide (no exaggeration) The silver 350Z on my website is one of my personal cars and has been my brake test-bed for over a year.
I have just registered with G35DRIVER so I can answer some of your questions directly and correctly. Later this weekend I will post on the rear kit
($795 pr.) and also a step by step install.

All parts are BRAND NEW.
The front kit price is $1395 for the pair, this price includes 2 6-PISTON BILLET CALIPERS, 2 ROTOR ASSEMBLIES, 2 BRACKETS, 2 BRAKELINES, PADS, AND ALL THE REQUIRED NUTS, BOLTS, LOCKWASHERS , AND FLATWASHERS.
Here's some pictures of the components:

The caliper pistons are stainless steel.
Note how thick the pads are!

The brackets have pressed in steel inserts for the cailper bolts so stripping isn't an issue. All the hardware is grade 8 or better and zinc plated.


The front rotor is 13.06" diameter, 1.38" thick, as you can see the vents are huge! Note the beautifully sculpted rotor center.


We have the best quality brakelines made for me specifically for my kit with the correct fittings.
This kit is completely BOLT-ON with no modification made to the spindle or car.
The caliper overhangs the mounting surface of the wheel by approx 1.5 inches so check your wheels for clearance. I dont accept returns on brake kits since we would never resell a kit that had been installed. I would not want to take a chance that someone had damaged or contaminated any of the parts.
I accept VISA/MC by phone or E-mail or you can send check or money order.
I normally use UPS ground for shipping and it's usually less than $50 per kit.
I usually have the kits in stock and it takes a just day or two to box 'em up and ship 'em out.

Thanks very much,

I only have the front kit. So I still have the stock rear brakes (which has the parking brake).

 

HOW ABOUT A GROUP BUY then DAVE ?? =))

Check my other thread with measurement photos, My kit did came with 13.6" rotor, not 13.06 rotor. fastbrakes.come sells it as 13.6 Kit, not 13" kit.

You have to measure from the face of the hat. I meaured mine, it's 1.5" from the face of the hat to the out surface of wilwood caliper, It's 2" if you measure from rotor surface.

Because my current OEM hat to Spoke is 0.75", I might be able to get away with 0.75" ( 20mm) spacer. I think you'll need similar size spacer. You mighe be able to get away with 15mm spacer if you have currently 1" clearance.
There is no way you could fit it in without a spacer, unless you get 25 off set wheels.

 

Firefox - do you think the BBK changed your offset (pushed out) at all? I'm running 35mm offset on my sedan already, so I don't want any further offset.
