Can you elaborate on what criteria you are most interested in? AP Racing kits have been offered for various Nissan vehicles since the 300ZX, and specifically for the 370Z since before it was sold to the public. There are a few different options currently available, along with a new, mind-blowing option that should be arriving in the Spring (fingers crossed!).

While both companies offer systems that are well-balanced mechanically, the thermal front/rear balance of the AP Racing system is currently unmatched. If you ever plan on tracking the car, this fact alone will make pad selection much less complicated when going to different tracks and running in different conditions (dry, wet, hot, cold, green track, etc.). Using too heavy of a disc on the rear is not really a problem on the street, but it does not make much sense for performance use. Not only do you get to drag around all that unnecessary weight, but the temperature rise is much more different front to rear that it would otherwise need to be. As we have also seen on the R35 GT-R, running rear brake temps that are too low creates a situation where the car can be optimized at one end of the temperature spectrum or the other, but not both.

Describe how you plan on using the car and I can offer up what I know from experience with this platform. Others will probably also chime in with their results. With all that, you will probably be in a better place to make an informed decision.

my parents put these on their GT-R about 4 months ago

along with uber hard brake pads for track days and softer ones for daily driving.

the hard ones almost tore my face off :roflpuke2:

I might get a brake upgrade when my current pads are worn out

I'm with Chris on this....The AP Racing BBK is a better full package. The big thing for me in the AP brakes is the weight. They are very light: calipers and rotors. Performance wise: I really liked the braking with the AP racing BBK when I drove my friend's car. It had good feel through the pedal and great performance without wear. I have also driven a car with Stoptechs and I can say that the one thing that stoptechs have are stiffer calipers, which do help in feel and performance on the track, but as an overall package AP all the way....

Sickness.

How about a hint? Are we talking carbon rotors here?!? :excited:

They can be done.. and while carbon ceramic matrix rotors would potentially last the life of the car.. there is a price that comes with it. Unfortunately the volume with the 370Z owner probably wouldn't justify it.. :/

What Chris is talking about is with traditional iron rotors.. but some really wicked design changes with other components.. and I've probably said too much..

@Chris: Now that I have a daily driver, the Z will become my weekend/track toy car. From what it sounds like with the advantages in weight and thermal properties AP sounds like a good choice... Are there any positive points to the StopTechs at all? They are more expensive but thats not always justfied by performance...

Oh you better believe I was already looking at those :rofl2: ... but as much as I'd like to I can't really justify 50% of the cars value in brakes alone :eekdance: Although if they would really last forever that would help, is that actually a realistic expectation, they would probably see mainly street use anyway.
Those are the GT-R brakes right, would they fit a 370Z?

Seems there are quite a few people with secrets on this board, I need to get on the inside track... I don't have the patience to wait until spring, but I will be waiting to see just how much they can change brake rotors.

I'm about to ditch my e-brake and still looking for lighter weight hat option on rears...

You don't have to.. We have the AP Racing track rears which allow you to use the e-brake as long as it's in a parking brake use.. due to the aluminum (and super lightweight variety) hat..

I was asked to create a separate thread and I haven't.. but you're good to go with the lightweight rotor/hat assembly that works with your current caliper.. with no changes to the e-brake..

I don't think it's rotors.. *cough* *cough*..

and i dont have specifics.. but can't imagine it wouldn't be attached to some old-school press releases.. STILLEN : AP Racing Unveils Revolutionary New Brake Caliper Design

AP - Chris can elaborate.. or hunt me down.. he opened the door.. :tiphat:

those look beautifull maybe il wait and see what the "suprise" is instead of looking for the current AP racing BBK.

Looks like art. Looks expensive :)

probably madly expensive :roflpuke2:

I would not be a good source to comment on the S-T's, but from what I hear from people who have tried both (and others), they are very satisfied with their purchase of AP's.

AP Racing has been making brake systems and braking components for around 100 years in total. Since 1967, they have over 660 wins in Formula 1 and supplied 10 of the 12 teams in 2010. Many of the advantages learned over the years are pretty hard to detect, but make measurable performance gains. Don't be fooled by over-simplified and questionable marketing graphs -- the true measure of braking performance is from behind the steering wheel. And from that vantage point, the true benefits of an AP Racing brake system cannot be denied.
