For those with upgraded Z32 bbk's or knowledge of, whats the proper part numbers used as far as the 30mm aluminum 4 piston calipers go? I will be getting these parts new in the near future. Also, I've did some research and found that the caliper will bolt up to the Maxima holes no problem, but if I use a Cobra rotor, then what modification has to be done besides removing the dust shield (i.e. control arm)??? Thanks in advance.

 

You will need a relocation bracket if you decide to go the BBK Route. Matt or Jeff should be able to help you out there. You will also need the conversion brake lines. BrianV can help you there. I have heard you might need to do some grinding on the spindle but Im not certain about that.

 

If you do a true BBK, you will need to determine whether you wish to use the 04 maxima rotors or the Cobra Rotors.
If you do the 04 Rotors contact matt or go to http://www.mattblehm.com/300ZX_brakes.htm
If you use the Cobra rotors you will also need the centering rings go here for more info

Both kits require the use of 30mm calipers, and relocation brackets.

Using larger rotors requires the need to trim down the heat sheild, if not the rotors will rub.
If you go woth the 300z setup, rotors and calipers you will need to have the rotors milled down, trim the heatsheild and grind down a section of the lower control arm.
These are pics i took when doing my 300z setup,...
this is why you need to mill down the rotors, if not they will rub the inside of the caliper,..

removal of the heatsheild,..

Grinding of the lower control arm,...

 

Nice pic of the upgrade FLAVOR_24/7. It will come in handy for me later on in the future. Thanks either way it is not my thread that I started.

 

Thanks guys, but back to ym orig. question.....does anyone have the part numbers from Nissan for 300 aluminum 4 piston calipers?

 

Best bet would be to contact the dealer if you want the specific part numbers.
here is a site that describes the differences in the calipers, they go by year model,..

41001-45P00 is the right caliper, and 41011-45P00 is left side. These come without pads or shims.
IMO, they are not very good. I've seen them on local maximas, and the setup looks janky. And if you're gonna spend money to buy them at the dealer, just save a little more and get a real complete brake upgrade which is what i'm saving for.

 

Ok, but for which model of caliper are those part numbers for? 26mm aluminum, 30mm aluminum, or the 30mm iron?
Whats "janky" about them?
There solid 4 piston calipers. Paired up with the BBK kits being offered they are a nice BBK setup.
I agree that doing the Z32 calipers and rotors isnt a true BBK, but the rotors are thicker then the maxima's so they do dissapate heat better and eliminate warpage and the four piston calipers do grab much better then the maxima's single piston caliper.
Which complete brake upgrade are you saving up for?

 

Those are part numbers i had written down at the dealership when i asked for the 30mm 92 TT calipers. I don't like that the car has to be grinded and stuff, and supposedly the brackets sold on the org are not very strong.
My buddies around here have huge brakes on the maximas, and convinced me why it's better to get their kit. The rotors have aluminum middle sections, so they're lighter too. I think they are made by like AP or Brembo i believe.

 

I havent seen anyone that hase been using the relocation brackets complain about them being weak nor seen a case of them breaking, but the guys sourcing them could answer that better.
The only time I saw it mentioned was here,..
http://forums.maxima.org/showthread....ation+brackets but others who have actually ran the setup have had no complaints.
I myself do not have experience with them, maybe in the future. I simply have the Z32 setup.
I know some of the guys (vsamoylov) are now using the lighter two piece Cobra rotors also but it looks like he is having some small issues.

i think his issues are getting wheels to fit since his 18" maxima wheels wont....u need aftermarket 17"s and bigger and possibly spacers..thats his only issue...i have Matts brakcets with 12.6" maxima rotors and i think the brackets are a nice quality made strong product ill post pics tonite

 

So what I'm looking for is 30mm aluminum calipers, custom mounting brackets, nice pads, a pair of compatible SS lines, and hit the conttrol arm with my grinder?? I got some lightweight 19 with a nice "outward" spoke design (Axis Hiros), so I'm not worried about clearance. But my only issue is my stock SE-L 16" 5 stars. =(

 

If you buy any one of the kits, they will have the relocation brackets.
Your Stock wheels will not clear the calipers, or any of the rotor setups being used.
You may not have to grind the control arm with the larger rotors, they may sit further away from the control arm. Im not sure though.
I used the 300z rotors and they required the grinding.

 

o4/05 maxima rotors and 13" cobra rotors do not require grinding of control arms...on a side note..had anyone tried sahving a few MM off the calipers instead fo rotors...just fro ****s n giggles.....no tthat i care cause i have matts 05/05 maxima BBK

Mike grinded his caliper braket for better clearance with the J30 setup.

 

Im sure you could take some off the inside of the caliper, I remember reading that some 240 guys saying they did it with a dremel or something of that nature.
