So I've been eyeballing the proto's brakes. I really like that setup but don't know if they'll offer it in the production versions.

Been studying the photos and ALL of the different ones in camo have a 4+2 setup. The proto have 6+4 with larger rotors. It's noticeable because the rotors have almost no gap in the rim. At the end of the day, at least it isn't a floating rear caliper like the Civic Type R.

Probably a Nismo exclusive? Is there a noticeable difference in a 6-piston vs a 4-piston and a 4-piston vs a 2-piston brake?

the protos are the actual GTR brakes the pre production cars look like akebonos similar to the 370 just with a slightly reshaped caliper.

the proto looks to be running the 390mm brembo rotors

as for floating the rear brakes on the proto are floating same as the GTR and rattle like hell

There's the answer I was looking for. I just couldn't figure out where they got that setup from. I highly doubt it'll be a 6+4 setup they have for the GTR for cost reasons.

I never knew the rear brakes rattle that badly on the GTR. I thought they were all fixed calipers for the GTR. I could be wrong.

Now question number two comes to play: Does the Brembo brakes perform better than Akebono? They look identical in structure and are both fixed calipers. I guess it'll boil down to the build material and QC.

its a floating rotor set up that just means how the rotor is affixed to the hats. and yea the rear ones on a rough road can sound like marbles in a glass jar at times.

Yes, you can expect a noticeable difference.

The Akebonos are excellent brakes, however, early cars with Akebonos had pads that weren't up to the task, and many early Z and G37 reviews were able to easily overwhelm the brakes on a track. However, it was soon discovered that better pads and higher temp brake fluid greatly improves the Akebonos. Maybe not to the point that they survive track abuse, but they don't give up after 1st lap like they did in 2008.

I have a Q60 coupe (it's actually a 2014 G37c) and I removed the cast steel brakes and retrofitted the Akebonos. There are several advantages to the Akebonos, the biggest being that the calipers were FAR lighter than the single piston crap I removed. Also, long-term maintenance is improved, the Akebonos don't suffer the typical issues of floating pin calipers. And obviously, they look very good behind a wheel! I actually chose to use the OEM spec pad and fluid for my Akebonos as I don't drive my Q60 any where near hard enough to need upgraded pads.

I have 255 wide tires in front, and 295 wide tires in rear, and the Akebonos can bring my nearly 4000 pound coupe to a halt in startling quickness, I can even get the ABS to kick in if I really lay on the brakes, my point being that the Akebonos will be more than up to the task as a base brake on the new Z. If that's the case that Nissan makes all non-Nismo Zs Akebonos, that'll be a huge benefit to the car. If you are an enthusiast with a new Z with Akebonos, just upgrade your pads and brake fluid and they'll serve you pretty well!

the only real weakness of the GTR set up is the drilled rotors crack if you look at them wrong

Slotted rotors always hold up better than drilled for heavy track use, still allowing dust excavation and cooling. @MCN1SMO since we've seen the proto with GT-R brakes, any chance that will make it into the Nismo Z? That would be awesome, factory backed and plenty enough for modded Zs also.

I still won't trust the stock Akebonos even with those upgrades for my use. Track temps are high here in CA, I don't want that potential fade hanging in my mind. Will swap for StopTechs or Brembos on first chance....unless Nissan gives factory options on BBKs.

I'm aiming for the sports version as it's rumored to have larger cooling system with upgrade suspension and brakes. I'm not a huge power junkie unless Nissan decides to go the 300hp version and save the 400hp for Nismo exclusive. Was curious about where and differences stand. It's just two more days and we get the official reveal!!!

Here's how the production model Z's brakes look compared to the Z Proto's brakes.

A few YT auto reviewers kept referring to the Akebonos as Brembos.
