A few months ago on the Speed channel, they had the Vette running with other exotic cars, ie AstonMartin in the 24hrs of LeMans. All the brakes were glowing orange/red! They showed a bit of the night racing and the glowing rotors looked awesome as the cars passed! Made me want to go out and get a set... but then I realized the cost of these brakes, LOL! So I opted for a 6/4 pot 14" Rotora set instead.

See: http://www.zeckhausen.com/Nissan/350Z.htm for the detailed kit descriptions, photos and pricing. StopTech (as of today) doesn't yet have the pricing for the 6-piston kits on their website.
The 350Z has three different front kits that can be combined with either the 2-piston or the 4-piston rear kits. (Exception: the 13" front kit can not be combined with the 14" rear kit.) There's a $100 savings by ordering a front and a rear kit at the same time. But since there are five possible 4-wheel combinations, I only list the front and rear kits separately to avoid confusion.
332 x 32mm 4-piston front ($1995)
355 x 32mm 4-piston front ($2595)
355 x 32mm 6-piston front ($3195)
328 x 28mm 2-piston rear ($2295)
355 x 32mm 4-piston rear ($2495)

we have the 6-Piston kits up on our site as well now:
http://performancenissanparts.com/ca...=stop+6-piston
You can always contact us for more info on the kits as well as any quesitons regarding pricing.
We will be installing this kit on my car as soon as it is done with being in the body shop, so I'll let you all know first hand how everything is!

Our competitors always claim, "more stopping power," with regards to 6, 8, or more pistons in a caliper. "Stopping power" is a meaningless phrase. On this application, our ST-60 caliper will be putting out the same amount of torque as our ST-40. The torque will be distributed over a greater surface area however...that's it. Essentially, instead of four larger pistons, you'll have six smaller pistons that have an equal total piston area.
The main reason we released this system is because everyone asked for it! Over the last year I've received numerous PM's about it, and many customers have asked, "when are you going to come out with a six piston for the 350Z." Many of the car show attendees have begged for it, and we have lost sales to competitors for the simple fact that they have more pistons in their calipers (which is ridiculous). Additionally, we have a number of 350Z customers that have been running our 355mm four piston kits for roughly 3 years at this point. Many of these individuals track their cars and may be considering a caliper rebuild, etc. We will be selling the ST-60 caliper and bracket upgrade separately for these customers. They can get a fresh set of calipers, a new look, and a performance upgrade in one shot.
You asked for it, we built it. Now there is a superior six piston caliper kit on the market, with all of the other good things that StopTech brings to the table...proper brake balance, reasonable replacement part costs, technical support, racing heritage, etc.
I'm not sure if any of you know this, but just like our four piston has won races and championships in World Challenge and Grand Am Cup, the ST-60 caliper is identical to those found on the LG Motorsports Corvettes in Speed World Challenge GT. They won two races last year, got a couple of poles, etc. Lou's been running this caliper on his car for 1 1/2 years now, and he will be running three cars with this system this season. I'm editing photo size...will post shortly:

**** they look awesome.
PM Sent.
Can we get some more photos posted please.
So the actual braking force is not increased, but the pad should last longer during track use?
Is the logo in the 6 piston a bit too big for the space? Doesnt seem to have the same spacing around it as the others?

And here's a shot behind the stock wheels on my (non-supercharged) SRT8:
That should give you a sense of scale of the logo.

No - that was just a demo stand to display the ST-60 caliper and rotor together. It shows a left front trailing caliper (behind the axle) in the 3:00 position. On a 350Z, the caliper would actually be in a leading position (in front of the axle) at about the 10:00 position. The orientation about the hub will be exactly the same as the ST-40 caliper kits.
Here's a shot of a left front ST-40 on a 350Z. The ST-60 will be in the same orientation, only much bigger.

If budget is not as big of an issue and you have plenty of wheel clearance, then my favorite choice is the ST-40 14" front and ST-45 14" rear. The ST-40 and ST-45 calipers look the same from the outside and this combination has the best, most balanced appearance. You are limited in pad selection for the ST-45 caliper to just a few compounds, all of them street-only. But since you said you were not tracking the car, that works out fine for you.

By the way, Nissan and Porsche share a leading caliper design, with the Nissan calipers clocked about 15 degrees closer to the top of the rotor than Porsche:
There is no performance advantage of a leading caliper design over a trailing caliper design. However, there is an advantage in having the caliper as close to the 3:00 or the 9:00 position as possible in order to minimize pad knockback due to wheel bearing deflection under race conditions. See: http://stoptech.com/tech_info/wp_knockback.shtml for more details on knockback. The 350Z (and G35) is more prone to knockback than some platforms because the caliper is significantly above the 3:00 position. This is not something that will affect the average driver, even the novice or intermediate who goes to the track. But the advanced or pro level driver with race tires may run into this issue. Also, the position of the caliper on the 350Z makes initial bleeding a bit harder, since air can remain trapped behind the caliper piston. For this reason, the installer must tip the caliper forward to bleed a newly installed Brembo or StopTech caliper for the first time. Not a problem with most other platforms, where the caliper is closer to the 3:00 (or 9:00) position.

That's a great answer Dave, to Johns question! BUT.....then why did Stoptech re-clock their 14" rear caliper AWAY from 3:00?
Looking at caliper positions over the years, there seems to be many differing opinions on what is best. I need to find a pic of Gordon's F1......OK, just did that....he mounted the front caliper BEHIND the axel in front, and in front of the rear axel. I would think mounting in the rear in front would help weight distribution, but I'm sure there are many other factors involved.
