AP Racing Big Brake Kit Installed!

travisjb · 08-09-2009, 01:46 AM

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:

Ultima GTR which has world record for 0 to 100 to 0, 0.5 sec faster than the Veyron
most of Formula 1, LeMans, ALMS, Grand Am, NASCAR, WRC and Champ Car
cars 1, 2, 3, 4, 5, and 6 of the Top Gear TV show fastest lap chart AP Racing Limited Edition Competition Gray Calipers Are Here! : STILLEN
and now my humble 370z!

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.

travisjb · 08-09-2009, 01:58 AM

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!

I'm scared to ask the price

Dee@Amplified · 08-09-2009, 04:22 AM

Props to you for getting some of the best products out there and building an amazing car man... Doesnt get much higher than AP Racing Brakes, you got an awesome set there.

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!

Valentino · 08-25-2009, 12:46 AM

Congratulation on this marvels BBK. You got one of the best. if not the best.

I don't think cross-drilled are for looks. I think that cold air inter the vent in between the disk,and hot air exits the disk throe the holes. and i also think it's good for wet weather. their lighter too.

cross-drilled also have their down side. they crack.

I don't really want to turn this into a debate. but i searched and found this nice write up Cross Drilled VS Slotted Rotors

If a respectable company like Stillen,and AP Racing work on a break kit. "exclusive for the 370z". Why did you have to do modification to correctly fit the break system? Or are they just off the shelf parts that they put together?

travisjb · 08-25-2009, 11:06 AM

Thanks for your note... my belief is that slotted delivers the venting benefits without the hassles of cracking associated with cross-drilled... to each, their own... re Stillen engineering, they did everything they could to ensure ease of install, but they can't control how nissan designed the backing plate. And putting a custom backing plate would drive up price. All other aspects of the install were straightforward.

Corect me if I'm wrong, but I could have sworn that the original purpose of the slotted and cross drilled rotors was originally to help with degassing. Back in the day when the pads would heat up the slots and holes would give the gas from the pads somewhere to escape which helped prevent a decrease in breaking performance. Also from what I've been reading, is that the slots still help keep pads clean, but the original reason of the slots and hole isn't really needed with pretty much any street pad any more and would generally be for looks more than anything else. Again I could be wrong and if so feel free to correct me. Also I'm assuming that since these fit the sport package equipped 370 it will also fit the NISMO model as well.

I am going to have to sit down soon and do a full, top/down write-up on this topic. In the meantime, I'll say that cross-drilling was developed initially a long time ago to reduce rotor weight. Benefits that were discovered were increased pad bite (more leading edges), better wet performance, (slightly) better cooling and elimination of pad off-gassing effects.

Pads today off-gas very little -- at least after their initial green bedding. But the other benefits remain. They are not ideal for racing or hard track use as the holes add stress risers, which can result in premature cracking. But for street and high-performance use, QUALITY drilled rotors usually perform great.

Looks? Well, that's up to you!

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?

Mike · 08-09-2009, 11:00 AM

awesome brakes!

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

ChrisSlicks · 08-09-2009, 12:35 PM

Thanks for the writeup Travis. I think this might be on the cards for me next year, a little pricy but fixes the fatal flaw that exists in this car.
