Z32 Brake upgrade brackets
Found a supplier for brackets that will allow 4th gen owners to use the stock Brembo equipped 350/G 12.75" rotors with the Z32 30mm calipers. Without a bracket we had to mill down stock Z32 size 280mm rotors, or about 11" and now you can get 12.75" rotors! Huge upgrade. Price is $120 and it is a quality product from a supplier local to me. Pricey yes, but it comes with grade 8 bolts and shims and directions to install. I get a PM at least once a week asking about brackets and now they are available. Now some milling will be required (about 4mm off radius to be safe) to ensure good pad contact and allow the pad spring to fit but this is a bracket available now from a reputable supplier. Rotor and pad options are numerous and milling can be done at any machine shop for about an hours labor cost.
IF YOU HAVE THE 26MM Z32 CALIPERS THIS WILL NOT WORK FOR YOU. YOU MUST FIRST UPGRADE TO 30MM CALIPERS Steel bracket: http://www.z1motorsports.com/imagema...600&page=popup http://upload.z1motorsports.com/Z1Z3...racketKit2.jpg 350/G Brembo rotors vs stock Z32: http://www.z1motorsports.com/imagema...600&page=popup |

Would these work on the rear of a 4th Gen using 350z rear vented rotors & Z32 alum rear calipers? (I have an idea for a e-brake in the rotor hat I'm working on)
|
No, but I think the rear maxima brakes are fine up to moderate track use as long as you have the proper temp pads and good rotors
|
Are these brackets a direct bolt on with no modification required to line up the bolt holes?
Is the Z1 site showing the exact ones your talking about from your link above? |
Wow cool find!!!!! This means they'll fit the 3rd gen as well....same brake setup!
|
Direct bolt on as the brackets are meant for the Z32. The Blehmco brackets have bend in them but these brackets are a different design and should fit with little or no grinding. All of the supplies should be here by the end of next week so I will post back. They sell cheap aluminum brackets on ebay for the 240sx brembo upgrade but the Z1 kit is definitly the one to get. Not going to cheap out on that aspect of the kit. The only modification will be to mill the rotors down slightly. It fits the Z32 with almost 0 modification so it should (fingers crossed) fit onto the maxima with very little milling and shims to center(as is common with most BBK kits). The rotors are a true 12.75 and 30mm and Ill likely mill them down about 4mm off the radius so Im assured of good pad contact and no clearance issues. So its not a perfect kit with 0 milling but nonetheless it is a great bracket that is available now. IF YOU HAVE THE 26MM Z32 CALIPERS THIS WILL NOT WORK FOR YOU.

Somebody asked me to ask you to wear that blue dress when you test drive the brakes....

The caliper doesnt "need" grinding for the Z32 so it shouldn't for the max either but even if it did need grinding it would only be slight <3mm/1/8" and off of the extreme edge of the caliper. A copy of the directions can be found here and they mention the grinding that would be necessary:
http://www.z1motorsports.com/upload/...20Brackets.pdf Like I said, this set-up is not a pure "plug and play" as the Blehmco kits were. These kits are no longer available however and this is the best option out there for us right now. Im not saying "slight grinding of the caliper and milling of the rotors is necessary" to try and sell the kit as I have nothing to do with it. The caliper will likely need some grinding to ensure safe clearance and the Z/G 12.75" rotor will definitely need milling along the same lines of the Z32 set-up without the Blehmco bracket or about 4mm off the radius. In theory, one could find a rotor for another Nissan that is say 27mm thick and about 12.4"/314mm in diameter and it would be pure plug and play. Most of the cheaper rotors for the Brembo equipped Z/G are not a true 30mm thickness nor 12.75" in diameter anyways so it shouldnt be hard if thats what you wanted to do. If this kind of modification scares you then I would not get it. I enjoy a DIY mod so I am looking forward to it. |

Thats an idea....I think the 6th gen rotors are about 28mm thick and 319mm/12.5". The diameter would still be iffy. EIther way once I install it I will post up the maximum thickness/Diameter for the kit.

|
That's 1 1/8" eyeballing it not with a dail caliper.....but still
|
I've got a spare set of 6th Gen front rotor (Stillen) that you can borrow for an experiment you pay for the shipping.....

The only issue I can think of is the Caliper is completely different and the pad might not clamp fully onto the rotor and that would be a reason not to use it. These brackets are designed for the Z32 calipers and these certain rotors. I should have all of the supplies in by the end of the week as Z1 is only a few hours away from me so we will find out shortly. Once I get them all on I will try to remember this and cover the shipping to get the rotor here. Lord knows the .org needs stuff to be cheap and easy.

All done. Pictures to come

Overall the upgrade didnt go very smoothly. I started about 4pm and finished about 9pm. However, 3 of those hours were spent on the first side just figuring out how to make it work and 1 hour was spent driving to Lowes in 4 o'clock rush hour in Atlanta for washers. The bracket put on the 4th gen puts the caliper far too close to the rotors and you cant bolt it up. Quite a few washers are needed to get in in the right position. It would actually be easier to trim down the bracket, which I still might do. Also, more grinding of the caliper was needed than expected but I overdid it a bit so as to have safe clearances. Ill see how popular the upgrade is now that pictures are up and if the interest is there I will do a proper write-up

I wouldn't risk my life with that set up man.
Be safe. Those hackets seem like a bad idea. |

I've measured them (6th Gen Front rotors) and I'm sure now they're like 1 3/32 thick and would be perfect thickness and diameter as well!!!
|
Wizard, the bracket was $120, the rotors were $120 and another $40 to get the pair milled down, the brake pads were $60, and I got the calipers/lines for $300. The whole system probably cost me about $700 so not bad for something unique. To solve the washer issue one can buy the Z32 caliper bolt which is longer as I understand/hope. Still catches plenty of threads as it is now though. Safety is always a top priority.
Cmax, 319mm rotor with 30mm thickness would be perfect. Are these the specs of the 6th gen? Overall, now that I have done all of the leg work I think the upgrade is great. Obviously, my opinion is biased but the bracket is steel so it can be tracked safely, the rotor is on par with the biggest kits available for the 4th gen, and all of the parts are readily available and cheap. Everybody says the Z32 caliper is outdated but caliper technology hasn't changed since it came out so that argument is really just wrong. Its basically a BBK that can be pieced together for very cheap which, as we all know, is of paramount importance here on the .org. If you got cheaper rotors and pads and rebuilt calipers from the JY, all of the necessary components could be had for about $600 |

Thanks Fixer!!!!!!!! |
Z1 has the same kit but with better quality parts and you can buy the Cals there as well. Would be a 1-stop shop for the pieces for this kit.....but thats if you read first

Aluminum brackets? The Z1 are steel and I like to autox so that why I went with the more expensive option. Aluminum will just crack sometimes, hit or miss really. The EBC gold? I looked into those but nobody had them in stock. I needed them fast

Who else makes steel brackets? Nice set-up

that 1 mm would matter though. Just more grinding really so not too much more work

Here are the pads I used for reference. Great pads and very reasonable on price

No problems as of yet, except having to relearn how I brake because the stopping power is absurd. Cold or hot. At about half the cost of an aftermarket all-in-one kit I would say this is more than a steal
