Did the G35 DP upgrade...finished product ---> http://forums.maxima.org/8431140-post83.html

I have 2 choices on going with a bigger brake setup...both utilizing a 12.6" rotor and I believe same relocation bracket.

Just asking...What would you do?

300zx 30mm aluminum 4-piston caliper
-OR-
'06 G35 2-piston caliper

Yes, only the fronts for now until I look into a better rear option.
I'm looking more towards better functionality and I know the 4-piston might be a little overkill.

I am assuming the G35 calipers are the same as going with a 6th gen caliper set-up, just with an added piston? They sure are heavy too...14lbs each. (stock calipers are around 10.5lbs each)

**UPDATE**
Just some info I found on the G35 vs 300zx calipers...looks like G35s are better in most ways except being 4-piston. (no, I don't track my Maxima)

2006 G35
35mm wide rotor support
43mm pistons (x2)
10x.08880 pad

300zx
30mm wide rotor support
40mm pistons (x4)
10x.06470 pad

All I know is the 300zx brakes are BA. In my opinion when you start doing performance mods then you have to upgrade your brakes too. I dont think any caliper made for a 2 door would be overkill on a 4 door...

 

Keep in mind, the 4 piston unit you mention there is over a decade old.

What info do you have about the G35 2 piston caliper set-up?

 

Well they are more current, they are from the Sedans only, not the coupes.

And you should buy a set from me and try them

 

I already have a Wilwood set-up, but if these 2 piston warlocks fit without modification as do the A34 set-up, that's a cool find.

 

How about a 12.6" 6th gen rotor and Brembo calipers from the evo?

 

Age of technology was the reason I was leaning more towards the G35s.
G35 calipers use a 12.6" rotor stock, so I figure the pad surface area might be greater than the 300zx pad surface area.

I already have spacers on the fronts so clearance wasn't really going to be an issue with the 300zx.

I need to set up the bracket that I have with the 300zx caliper and ensure the G35 caliper mounts correctly to my Maxima.

 

Reason I have those choices is because I already have both. Just asking those that might have the upgrades for an opinion.

It isn't 'IF' I am going Nissan BBK...I will be...just deciding on which route. I think I'll look into the G35 calipers...ensure fitment. Since they fit a 12.6" rotor stock then I know I'll need a bracket. I don't want to buy a rotor and have it shaved down to fit.

 

thanks for posting the info about the 06+ G35 calipers, i didn't know that caliper existed.

Who makes the caliper adapters for the 300zx that will accept the 12.6 rotors?

 

^^^^^^^ no one really for the 300z bbk to work, well you need the 13" rotors, well in the 6th gens at least

 

If the g35 calipers don't bolt up, why not use tha A34 calipers?

Weight of the calipers themselves is a silly thing to worry about, it's the rotating weight of the bigger rotor you want to be concerned about. Look for options that have lightweight rotors available.

And ideally, needing no reloaction brackets, such as the 6th gen bbk.

 

Because it was something out of the norm to do...and the enticement of 'dual-piston' makes it worthwhile.

Anyway. There's a thread in the Advanced Braking section outlining the G35 upgrade, if anyone's interested. No relocation bracket needed but I am having to shave some of the 'ceiling' of the caliper down (where the rotor passes through) to accommodate the 12.6" rotor.

 

Sounds like a wicked upgrade man, the 05/06 Calipers are much nicer than the 6th gen A34's too.

If they fit no issues, then I wonder if the 350Z brakes fit the Maxima also?

 

Well they (G35) bolt onto the same knuckles, for sure. They are just about 3mm off, necessitating 3mm grinded off of the caliper...which isn't something for the general basic-DIYer here.

The 2006+ G35/350z are the same dual piston setup...unless you go to the upgraded Brembo or Akebono setup. For a 2003-'05 350z it is a direct bolt-on upgrade to the dual piston design. The A34 upgrade is the only direct upgrade for us. No modifications needed...

FWIW, the 2003-'05 350z (basic) brake setup utlizes the same rotor as the '02/03 Maxima (11.65" rotor)...I have a spare '03 350z caliper setup but I'm fairly certain the calipers would need to be grinded down to fit a stock 5.5 Maxima rotor.

I've done stupid research on all this.

 

There's also the piston size difference = better braking force.

2006 G35
dual 43mm pistons

2004 Maxima
single 35mm piston

 

So read the thread little confused I want a bbk and the g35 seams awesome. If I bought these calipers what is needed to fit a 5.5 Gen I can shave the ceiling and grind 3mm (for the bolt hole?) no problem just wondering if I need brackets and all of that as I have heard of if the g35's will bolt up with only slight modification?

 

I'm currently in the process of doing this. The 'ceiling' where the rotor sweeps past the caliper needs to be grinded down about 3mm...(not sure on exact mm).

Other than that, it would be a direct bolt-on.

 

Sweet info for the community man! keep us updated on this one

 

Awesome let us know when you get all of that done, put in and pictures would be awesome I will be having this as well

 

Jeff, great info, this is a very interesting project and I hope it works out. Please keep us posted.

 

CopyPasta from my AdvBraking posts:
I was waiting to update the thread till I was done with the G35 calipers but here goes:

The calipers are not a direct bolt-on if mated with a 12.6" rotor. The holes line up just fine on the 5th gen knuckle, no problem there, but there is just a little bit of scraping from the rotor to the inside of the caliper. You either have to mill the 12.6" rotor down or you can do what I'm in the process of doing and mill down the surface area of the caliper itself. They're iron so milling down 3mm from the caliper shouldn't be an issue.

The G35 dual-piston calipers are definitely an upgrade over the 6th gen setup anyway...just not as direct of a bolt-on than we hoped.

For comparison's sake...and this is by no means an exact measurement. I measured from the inside 'ceiling' to the torque bracket mounting holes of the G35 caliper and a very-stock-fitting-to-12.6"-rotor-caliper.

The difference is evident. It's fine though, I have the tool now to grind down the inside ceiling of the G35 caliper so all is well on that aspect...pics are for educational purpose only.

 

Seems like a reasonable approach. FYI - I didn't have to do any milling/grinding with my 6G 12.6" set up.

 

You're right. I ninja-edited the post to fix my misconception.

 

LOL, get it together! JK.

Thanks.
