But if the '05-'06 calipers are 2 piston compared to the 4 piston brembos, then I see an advantage there at least! I was told by the dealer than the new OEMs were 4 piston as well, but I haven't looked in detail.

I am not talking to you anymore, since you don't even know how many pistons are on your brake caliper. Why bother. haha

hehe you really think it makes that big a diff. Just drive safe and try not to put to much confidence in that system without suspension mods. You'll live longer

Is it true that you can't replace the factory wheels with aftermarket ones if the car is equipped with rear active steering? I heard this from an M45 owner.

And BTW OEM calipers are 2 piston, but stopping distance is on par with the Brembos. One could see the only real advantage of the Brembos after an 8-hour track day when the OEM pads would be pretty much gone...

I just checked the '05 and '03 service manuals, and the OEM '05-'06 front calipers are dual piston, and the rears are single piston for both the Brembos and '05-'06!

WOOHOO!
Caliper & piston diameter are larger on the Brembo's rear, the front are where the real stopping power needs to be anyway!
Nice try, go study some more; why do you think they still use em' on the Z?

Give up man; Infiniti chose to use the savings on other upgrades while keeping the sticker price from changing too much, that is all.

Sorry but Brembos are 4-piston (f)/2-piston (r) my friend

'05 Coupes and Sedans:
Front: 12.6-inch x 1.1-inch power-assisted vented disc
Rear: 12.1-inch x 0.63-inch power-assisted vented disc

'03 and '04 Non-Brembo Coupes and Sedans:
Front: 11.7-inch X 0.9-inch power-assisted vented disc
Rear: 11.5-inch X 0.6-inch power-assisted vented disc

'03 and '04 6MT Brembo Coupes:
Brembo® brakes
Front: 12.76-inch x 1.18-inch power-assisted - 4 pistons
Rear: 13.07-inch x 0.87-inch power-assisted - 2 pistons

Yeah I could see the different pads having an impact.

Here are some specs for comparison:

'03-'04 '05-'06
Front Rotor: 12.76" 12.60"
Rear Rotor: 13.07" 12.13"
Front Pad Area: 8.73 in^2 10.09 in^2
Rear Pad Area: 5.34 in^2 4.12 in^2

So the Brembos have a slightly larger front rotor, much larger rear rotors for some reason, much less front pad area, much more rear pad area. No clear conclusions there! All I know is that my '06 stops on a dime with no fade. No complaints.

Yes, 2 pistons per side on the front, one piston per side on the rear. With the '05-'06, it's 2 pistons on one side on the front, one piston on one side on the rear. But with the force balance on the opposite side who can really tell?

And Brembo owners (unless running aftermarket pads) can only envy 05/06 owners for having virtually zero brake dust. My M3 on the other hand makes me cry. It only takes 3 days for my front wheels to look gunmetal haha.

03-04 G35 with Brembo's have a fixed caliper and is secured rigidly to the axle assembly and have 4 opposing pistons that force the pads against the disc.
The 05 G's on up have sliding or floating caliper that has pistons on only one side of the disc. Therefore, when the caliper acts, it must slide or float in order to bring the pad on the opposite side in contact with the disc. Nearly all original equipment calipers are of the floating type.
In a system with fixed calipers, like our Brembo's, not only is the mounting much more rigid, but the stiffness of the caliper itself is greatly increased. This manifests itself in enhanced braking performance, pedal feel, and consistantly even pad wear, this setup is known and used by the finest performance automobile and motorcycle manufacturers througout the world and Nissan still uses it on the higher end Z cars.

Been runnin' good ceramic pads for 10K; what brake dust?

I already acknowledged that this was the case. Obviously the change of brakes for '05-'06 was a cost-cutting measure, that was never up for dispute! All I was disputing was the lack of performance of the '05-'06 brakes, and if it's noticeable over the '03-'04s. I buy the fact that pistons on either side of the bad allow for more even pad pressure, but how much so? Pad wear on previous cars of mine with floating calipers has been virtually identical on either side of the rotor. Would I take the Brembos on my car instead if they were free? Probably, they're clearly a higher tech brake, but I might have to switch out the pads to get rid of any increased brake-wear or brake dust issues if they proved annoying.

So how many pistons are on the 03-04 G35C 6MT in total? Careful, it might be a trick question.

Let's try it another way. Go to the garage and check to see exactly how many pistons are on your calipers. The piston is the thing that looks like a little cylinder larger than a stack of quarters. Try to count how many are there.

No fade eh? I assume you havn't taken your coupe on the track?

Why don't you explain to the group why the extra opposing pistons reduce brake fade despite having virtually the same front rotor diameters and much less pad area?

Is it simply from more even force distribution? I don't buy it. I think that as the pad wears the force gets pretty darn even on the floating side. In this case given similar rotor masses I would say that the pad would have the biggest impact on the brake fade characteristics, but given the exact same pad material in both cases, I'd almost have to say that the '05-'06 systems would exhibit less fade given the larger front pad area and pad mass.

I've never tracked a car back to back with similar brake sizes with the only difference being 4 piston versus 2 piston floating, so if you have then by all means chime in and let us know your experience as well as your physical explanation.

Personally, I think the Brembos are just the only thing that '03-'04 owners have to brag about after the dash / cluster / engine upgrades in '05-'06. Just messin' with ya.

Rather than just give you the answer, I think you should discover it for yourself. Here are some images that should help out.
