AP Racing Big Brake Kit Installed!
For those of you that know AP Racing brakes, I think you will be excited to hear that I have successfully fit and tested their new kit for the 370z! Includes a 14.25" 6-pot front and 4-pot rear kit. For those of you that haven't heard of them, let's quickly cover their credentials... example apps:
Why I decided to make this upgrade... If you read my build journal and some of the other threads from folks that track this car, you'll notice that even with the Akebono sport package brakes, high temp fluids and track pads, people are experiencing significant degradation in braking performance during track sessions with hairpins and other intense braking zones. At first I thought I could resolve this with more airflow, different pads, etc, but after playing around with all that I just wasn't able to get consistent stopping performance on the OE setup. Why take chances with your brakes?! I bought this kit in order to get 99.99% confidence that I will stop predictably every time. In addition, as I move to stickier tires, I suspect that this car is going to need a lot more than the stock setup could offer. Larger surface area of contact between pads + rotors = more thermal capacity... Some more discussion here: Sport Pkg brakes up to track use? and here 370Z Brakes? Installation: I had the kit professionally installed by Redline Motorsports of Tempe, AZ. They primarily work on Porsche and Ferrari. They are a Brembo dealer but were seriously impressed with this kit. Install was reportedly straightforward "virtually bolt ons" - only downside noted was that there was trimming required to the OEM backing plates. Nothing a DIY'er can't handle with a grinder and sawzall. We are using DOT5.1 fluid. As for servicability in the future, one thing you'll notice about these is the huge opening for pads... swapping pads is drop-in, unlike some other BBK's What's in the kit: Choice of slotted, drilled or slotted/drilled rotors, calipers, stainless steel brake lines, mintex extreme metallic high-temp pads, all the hardware you need for install. I elected the slotted rotors. Cross-drilled are for looks. Slotted are for heat dissipation and performance. Testing and impressions: I am just getting started with testing, but first impressions... flawless! First and most importantly, I have experienced ZERO fade issues throughout the hot summer months here in the southwest. Including time at tracks in AZ and Utah. I have braked the car from 150+mph with some intensity and it was supremely stable and confidence inspiring. Stopping G's have increased and distances reduced. And to be honest, I am still exploring the limits of these brakes. You will see from a chart I post later that I am not yet fully exploiting these brakes. Why? Because I continue to underestimate how much stopping power is on reserve... It takes bravery and time to adjust to fully exploit a set of brakes like this, and well I'm still working on it! Where to get: Stillen : AP Racing AP Racing 6-Piston Big Brake Kits You may be worried about how much they cost but I offer this up for you: 1) if you act while your z is new'ish, you can probably sell your existing brakes for about $1K - lots of interested "G" owners, 2) you're going to spend a significant portion of this on quality rotors and still not have as reliable and powerful a setup, 3) they may save your ***! 4) One of the things you are paying for with these brakes is support. Since purchasing these, I've had all the access I need to Stillen's technical people to talk about brake pad options, servicing, etc. The responsiveness and technical skill of the folks I've interacted with at Stillen/Brake Pros has been 10x what I've gotten from Nissan for the car itself. I will continue to test different pads during the upcoming season and will update this thread occasionally with results. Questions and comments welcomed!

The pics above will be updated once I get my new Forgestar wheels... and by the way, obviously these fit with the sport 19 wheels... I am not sure about OEM 18s... I have also confirmed that they DO fit with the 18" Forgestars offered by Mike at DDM.
So, this morning I was at Firebird International Raceway West Track here in Phoenix. I pulled some data off my Traqmate to illustrate these brakes. Have a look. |

You'll notice that I have no trouble getting to 1.0g decel on street tires. I think there is more on tap, but as I said I'm still getting acclimated to these brakes. In fact, you can see that I did not consistently use all the brakes. You will also notice that there are no abrupt fall offs that would be indicative of brake fade. Another thing you may notice is that around 500-900 feet, I am using the brakes ~10-15% around a 1.0g right hand sweeper. I had a driving instructor that once told me 'the accelerator is an on/off switch, use it that way (gradually applied of course)... but the brake is not... the brake pedal has infinite positions' With these brakes and the s/s lines that come included, I find I am better able to dial in exactly the brake pressure I desire... that means more controlled and predictable trail braking. This will only get better as I move to sticky tires.
That's all for now! |

The Stillen link in my OP has the prices. This is an exclusive Stillen kit. Stillen engineering designed the kit in collaboration with AP Racing. Prices are marked down from list, which should help a little. One option for anyone whose budget is tight is to do the front and save rears for future date.
Thanks Steven! Now if I can work out the fuel starvation issue I've been having at the track recently, will be ready to rock! |

Very nice brakes.
I can't wait to see the 18" Forgestars. I hope they get to you soon. If you don't mind me asking, but what tire sizes will you be using?

Thanks. The matte black forgestars should set off the brakes nicely... and the overall combo will be much lighter. I am currently thinking 285 front 305 rear... but may adjust that depending on classing

Sure thing, Chris
I'd urge folks to think about doing this sooner rather than later, so you get a good price when you re-sell your OEM brakes. I got a grand for mine, but I sold to the first guy that came along. You can prob do better than that. |

Great question, I should have mentioned that before... when you use these brakes with a reasonably 'soft' pad like the mintex extreme that comes with the kit, they are PERFECTLY SUITED for the street... no joke, a lot less bite and jerkiness than I had with my stock brakes combined with hawk HP+ pads... having said that, you do not need these brakes for the street... I know you realize that... the benefit for you would be once per year and bragging rights in between events!
