whats needed for 12.5" vr-4 brake up grade ??
Hey guys what do i need to perform a 12.5" vr-4 rotor upgrade? is the a32 300z caliper mandatory or optional ?? and what are the options we have with the rear brakes besides $$ stillen or willwood stoptech .etc.. any mixing off j30..or..Q45..or perhaps the m30 ??? theirs got to be a nissan with upgraded rear brakes that cam fit the 4 gen maxima ??...

Well, as for brake upgrades, there is only two nissan vehicles I know of that we can mix with for fronts. The 300ZX (Z32) and the Q45. With both, you would have to mill down the radius of the rotor by 3mm due to the design of the hub mounting tab. All nissan FWD cars' brake mounts sit 3mm closer to the center of the hub then on their RWD cars. Now, as for the VR-4 upgrade, I have heard of ppl using the VR-4 calipers as well on 300Z's but I'm not absolutly sure if the brake mounts are the same on both. You can, however, use the 12.5 rotors with the Z32 calipers due to them being the same thickness as the Z rotors. You will need a bracket to compensate for the larger diameter and offset of the rotor. I have the design for this done (SolidWorks CAD format) and ready for machining but scrapped the idea in favor of the 13" cobra rotor upgrade. Had half of the cobra rotor bracket done but lost access to the machine shop I was using. Finally found another one thought so should be finishing that soon. If you have any questions lemme know.

q45 and 300zx uses same 13" rotors. and who said cobra and vr-4? nuts.
get 300ZX 4 piston calipers and rotors for front. make sure to ask for brake lines and the two bolts that holds the calipers.
and about the rear brakes...they don't do sh+t. no need to waste $$.
and about that 17" discussion, some 16" (like stock 300ZX wheels) fit perfect. if rims don't fit, get spacer.

about that mysterious bracket
but about them brakets guys ..hmmm am under my maxima every other week end fixin or maintaining somthing or another just gota make sure she runs on point since if she stops to run for some unforseen reson my intire life goes flop so i tend to make sure i see problems before they become any you diggg!! i really want to do this mod its been on my list for so long ang got every part in my mind am now saving some $ so i can go down to a local junkjard and scrap me some 300.tt.calipers ...but i really want upgraded rotors so it.s ''1'' vr-4..or..or ..2..''cobra..rotors right on ..i just hate having modified front brakes and leaving the rear stock i would like some type of nicer caliper but not the overpriced ones ..thought theyr was another model that hade 2 piston rear calipers that fit the max hmm so much for that i guess just rear cross drilles vented rotors are gonna have to do.....but how about that braket !!!!!!!!!!!!!!!!!!!!!!!!!!!...who makes it ?? is it only a do it yourself product ???thanks for your time guys ....

Any idea how much spacer would be needed? 5mm, 15, 25??

I think you need to assess the pad situation you are working with before you go upgrading your rotors. Pads will give you more increased stopping power than rotors will. The only performance reason for larger rotors if you are running on street tires is to dissipate the heat of repeated stops, like you would get during hot lapping on a road course. I can tell you right now that if you have 12.5 or 13" rotors and a decent set of pads you are going to have more brake than your tires will EVER be able to handle, unless you are running R compounds which I imagine you aren't. I'm buying a set of $800 R-compound tires and a spare set of wheels because my 13" rotors and MODERATELY upgraded pads stop too hard for my T1-Ss.
So I say analyze why you are doing this. If you want a bigger rotor thats fine. If you want to stop harder you need to get pads and tires, then worry about rotors. If you need the bigger rotor to dissipate heat then getting large rotors would be necessary.

so i can go to the yard and just rip em off. or like buy brembro crossdrilled for a 300zx and grind those down, would that work.? i need new fronts but i wanna do a full conversion to something big. how much you think itll cost to pull it off. ? searching......

YOUR RIGHT MR.187 .THATS THE DEAL
IT,S HIGHER PERFORMANCE IS WHY WE ARE HEAR TO MAKE THE MAXIMA BETTER THAT IT ALREADY IS ..WHY I AM DOING THIS MOD IS CUS SINCE I LIVE IN MIAMI THE WATHER HEAR IS INFERNO HOT AND ON ANY GIVEN DAY IT GETS LIKE 95 + SO WHEN I DRIVE I ALWAYS GO A LITTLE FASTER THAN THE POSTED SPEED LIMIT .SO WHEN I STOP MANY TIMES BEFORE IT HAPPENS IN A FLASH DUE TO STUPID DRIVERS .AND MY BRAKES FADE OUT ..SO I FUGURE WITHOUT BLOWING NEXT MONTHES RENT ..HOW CAN I RESONABLY MAKE MY BRAKES BETTER ..AND I,VE SEEN SOME MODS OF 300Z CALIPER UPGRADES WITH LARGER ROTORS AND IT LOOKS SPOT ON !! TO SOMTHING THAT WILL WORK ..AM RUNNING 235-40-17..CONNTINENTAL CANTISPORT TIRES AND THEY ARE GOOD .BUT TO THIS DAY AND JUST ABOUT ALL THE TIRES I,VR GONE THROUGH TOYOS SEEM TO BE THE BEST ..BACK TO THE MAIN ..I AGREE PADS DO MAKE A HUGE DIFFERENCE .INDEED ..HOW DO YOU GUYS LIKE THEM .."GREEN STUFF" PADS ARE THEY ANY GOOD ALOT OF AUTOCROSS FOLKES SWEAR BY THEM BUT I WANTED TO GET MORE FEED BACK ...THANKS GUYS ..

bob--cool then go with larger rotors if you think they will help, but please lose the caps lock key

I NEED FRONT CALIPER BRAKETS
WITH ALL THIS FIGUERED OUT .ALL THAT IS LEFT TO WONDER IS THE BRAKE BRAKETS !! PADS ROTORS LINES CALIPER..BUT THE BRAKET TO FIT THE LARGER ROTOR IS ALMOST IMPOSIBLE TO FIND ..WHO CAN I CALL OR GO TO GET A PAIR OF THEM ...THANKS..GUYS..95SE.140K MILES ..FSTB.RSTB.RSB.AGX.SPRINTS.17.W.235-40-17 CONISPORT TIRES..

thanks k max but _
I plan on using 12.5 or 13 inch rotors with the 300z caliper ..so since the diam of the rotor wont let the caliper bolt to the hub ..i think the brakets are requierd..dam i wish i can get in touch with some folkes who have larger brakes up front.. well .k max i know you know about this mod ans have been so helpfull i thank you for your good input and help ...peace

werd up mr.187 good thought
I personally try to modify everything that is within my learning or skill.. if i had a torch or plasma cuter i guess i could scratch up some thick aluminum or steel plates from a local machine shop ..but to be honest i dont have much hands on with that kind of mod.. HEY K MAX IF YOU DO SCRAP UP SOME EXTRA ONES OR CAN GIVE ME THE STENCIL OR BLUEPRINT SO I CAN GO AROUND AND SEE HOW I CAN GET THEM DONE ..THAT WOULD BE GREAT ..OF COURSE I WILL COMPINSATE YOU ..LET ME KNOW BUDDY ..OK.PEACE

WOW THANKS K MAX THAT WOULD BE KICK A**
SENT IT TO bamore@miamidade.gov ok and if you could a small explanation on how the design is set up to work correctly. to the stock maxima hub ...thanks a mill. k max ..your the man ..and i will let you know how it goes bud ...thanks
