13" Cobra rotor adaptor brackets for use with Z32 30mm calipers?

[CHARLIE2020]

Just what the titles says, where can you buy these, anyone here know and or have pics.

[CHARLIE2020]

Heres a pic of the Cobra brakes on a Maxima thanks to "mizeree_x" from G20.net.

if maximas can fit z32 brakes.. Id ask him, he would know right

[CHARLIE2020]

I've tried but I wanted an answer as soon as I could, thought maybe someone here would know.

[NismoSilvia270R]

his AIM name is the same. ask him. he is usually on.

i have his old max calipers, thats how i know him

[turtl631]

The guy "derrick" who does group buys on Z32 brake parts was going to make the brackets for S chassis cars, but there wasn't enough interest. I emailed him and he said if people really want them, he'll make them. I'd email him...I think we have 4 or 5 people who are really interested already. If he hears from enough people, he'll be motivated to make them.

No need. The same bracket used for the Z32 would work on all Schassis cars, there was a guy selling them a few years ago but he's disappeared.

[CHARLIE2020]

I did a search and found some forums that where discussing and moding there cars with these brackets in April/Mat of this year i'll try and find it, so maybe its still alive.

You need a simple 3/8" steel bracket for the caliper, and you need a hub ring because the bore of the mustang is larger than the bore of the 240.

[phrozen]

there are some z guys using z33 track rotors. i was on tt.net trying to source some brackets no luck. ginn motorsports is out of business and no one is making them as of yet

[turtl631]

Well, it looks like any source for these brackets, whether originally intended for Z32s or S13/S14, has disappeared. Does anyone have the Cobra rotors on an S chassis car?

[OptionZero]

aside from "bling"...why do you need 13inch rotors?

[Ritz S14]

These bastards charge way too much.

larger rotors offer more surface area for better heat dissipation or something like that... basically better cooling because there is more rotor for the heat to be spread across. plus, i find stock z32 rotors to be a bit too small for 17'' wheels.

[CHARLIE2020]

I just want them for looks (since im also rolling G35c rims know and my Q45's look small), I have Q45 brakes all around and that is plently brake for my S13.

[OptionZero]

i know what larger rotors do, i just didn't think a 13 was at all necessary outside of looks, as he mentioned, on an s-chassis that isn't pumping out, i dunno 800hp.

[Grandpa]

The person who originally sold them worked at z1 motorsports in georgia, ash or something. Check their website to see if he still makes something similar.

The most important reason to run 13" rotors in the front is that, teamed with the rear z32 brake setup, it yields almost identical proportioning front to rear as the stock brake setup.

Let alone 18" wheels, these are Q45/J30 brakes same exact size as Z32 brakes.

why should horsepower have anything to do with braking capacity.

"omg you dont need anything bigger than a 225 tire unless your car makes 600 hp"

[Gjohnson7]

There was a guy producing them om Maxima.org (I belive Jeff92se) but he said they wouldn't work for the 240sx. Not sure why, but I emailed him a while back asking since I use to have a Maxima.

[CHARLIE2020]

I doubt that, im sure Nissan made all the ears the same for all chasis of teh same year more less to save on cost.


Its like all the the Q45/J30/G20/S13/S14 can all use eachothers front brakes interchangably because all the offsets and ears are the same until you get to the later years and even then I've read there still the same with the exception of 14mm caliper bolts versus the previous 12mm bolts or somehting like that.

[CHARLIE2020]

Im pretty much over getting the Cobra brakes now anyways not to big on getting hub centric rings, I can settle with 12.5" that should be plenty noticeable over the 11".

[phrozen]

if your goign to use vr4 rotors dont get xdrilled ones. get blanks or slotted... read about it on tt.net almost everyone that has used vr4 rotors has had them crack or fuck up. thats why they dont sell the brackets anymore

[CHARLIE2020]

^^^ yeah i came across that somewhere, good point.

[turtl631]

13" rotors have some advantages, as mentioned; the bias with Z32 rears is pretty close to stock, whereas Z32 all aroudn has a decent amount more rear bias than stock. Also, running giant brakes can let you run cooler pad temps and therefore more streetable pads. Plus, they look good. I'd rather run a pad like Hawk HP+ or Ferodo DS2500 all the time on 13" rotors than throw in some Hawk HT10s at the track, eat up my rotors, and then put in streetable pads and rotors when I drive home. It depends what kind of driving you do as well; the track that I'll eventually be running at has faded some pretty serious brake setups on 240s, so I want to be prepared to deal with that.

Here's some info on the Z1 setup:
Kit Includes:
(2) 13" 2-piece rotors
(2) Caliper relocating brackets
Grade 9 fasteners
Nismo 50mm wheelstuds
Hubcentric locating rings
Hubcentric spacing rings
Installation manual
$750

ouch on the cost...that includes a lot though, and not everyone really wants to spend the money on 2 piece rotors. I just want the brackets and some hubcentric rings, the rest I can piece together myself for cheaper.

[OptionZero]

presumably a 600hp car will have to stop a lot harder than a 150hp or 250hp one

even 3z brakes are probably excessive performance wise for many people, provided they are matched with good pads

and 225 all around on a n/a KR car is just fine, probably even on a stock SR

just get a stickier compound, instead of running a weaksauce daily driver tire like the ST115.

but I don't drift, so I must not know anything about going fast.

[turtl631]

I didn't say anything about drifting. Look up Def's threads on FA about his experiences at Road Atlanta, which is the track I was talking about. He's been through several different pads on his Z32 setup and still has issues. He also runs giant Kumho MXs. Race tires would only exacerbate the brake problem.

[OptionZero]

wasn't responding to you, and he is running a turbo KA i believe. He's also a dedicated track monger, which is a are breed on zilvia.

[turtl631]

Gotcha, thought that was a stab at me. He's actually got a SR on stockish boost, but same idea. And you're right, he spends a lot of time on the track. It's hard to figure out a good track setup for a S chassis car because the vast majority of owners are into either drag or drift. I actually wish there were more people taking their cars to road courses, but I don't see it happening anytime soon. So...in the meantime, we'll have to figure out how things work for ourselves.

Plus, big rotors look cool :)

[OptionZero]

i know they LOOK cool, i just don't think it's worth the trouble to get 'em for most people

and if you want big brakes..get the Zeal multipiece rotor kit, its blingalicious

i've read Def's posts on FA, he runs at Road atlanta, he runs HLSD as well

interesting debate about big swaybar + softer spring rates (Relatively) versus smaller bars (no bars even) + stiff rates, should check it out

We made those brackets for Ginn Motorsports back in the day, but those brackets are actually not a direct fit for the S chassis. I recently re-did the new design for the Z33 track rotors w/ S chassis/Z32 calipers and the new brackets will be ready in a month.

[turtl631]

Ah, very cool. Projected price?

[FRpilot]

how big are z33 track rotors and how much do they go for?

F drift. I'm going all out track whore, massive power, little weight, tight suspension, as much braking as possible. I've been strongly considering McKinney's supra 13" two piece rotor kit, but what I'd really like to do is adapt the whole brembo system from a track edition Z to the S chassis, and not just use the track edition rotors.

[turtl631]

Use R33 brembos then, or piece together a wilwood setup.

[Twinturbozs]

Splparts.com is coming out with a BBK that allows you to use Z33 (12.75") rotors and brackets with your Z32 calipers. $500 i think, and the Z33 rotors are hubcentric.

[Ritz S14]

what does "BBK" mean?
