Lordrandall: MWS Motorsports sells a kit for the 300zx that is suppose to fit under 16" wheels but runs $550. pm me the info, i think i know who you are talking about.
I still havent heard anything from the machine shops that i have contacted. hopefully i can get those hubrings started this week.

timtiminy

oh yeah i forgot to mention this but those of you with Q45/J30 calipers can use this kit as well. Use of the q45/j30 calipers may allow for a smaller wheel as well but not sure how much smaller.

Lordrandall

PM sent, I think there are a ton of options here.

Any word on this? I saw the thread about your fire, sorry about that dude. Hopefully you can rebuild with that other S13. And rock some mega 13" cobra rotors on it

Are you still working on these? I'm looking foward to this and I have money in hand.

timlush

Interested here also.....

GoodOl'S13

what ever happened to this. im looking for a brake upgrade.

Yeah did this end up coming along?
Anyone buy the brackets?
Anybody out there?
...

timtiminy

i have 5 sets of brackets ready to go but no hub spacers so until i get those i wont be selling the brackets. sorry guys i've learned that machine shops are hard to deal with. hopefully i can get these out for you guys. I'll keep you all updated though

SicBastard

Please pm me when they're ready.

I'll take a set of cobra to z32 adapters asap.

Hooorahh!

pm me when there ready ill probably be up for a set .. please pm me ur contact info as well as location and so on so that when there ready i can just pick a set up =-)

Can Maxima guys use your brackets for their 300ZX/Cobra swaps?

Also, I hear if I have a 4-lug, I don't need the hub centric ring, as I'll be re-drilling the rotor, and the new holes will center it just fine.

sil80

Lordrandall

Depends on how he made the bracket. But there's already a guy on Maxima.org that makes a bracket for Maximas and the hubcentric ring.

i just want to confirm, i have the complete R33 rotors and hubs on my car. this kit will work as well right?

i'm still interested. hell, i can try it out for the price.

timtiminy

I would suggest the hubcentric rings even with a redrilled rotor for a 4 lug.
I will have the r33 kits as well, its a little different than the z32 kit, but i will have both.

sil80drifter

Lordrandall, Jeff says hi =]
He also says that although his brackets look similar to the ones Tim makes, for Maximas the spacing may be different, and the caliper will sit oddly offset toward the rotor when used on a 240SX.... but I was under the impression that both Tim's and Jeff's brackets were the same exact thing, dimensionally
(3/8" thick, same bolt spacing, etc).
Can you comment?

sil80

timtiminy

the brackets may have the same offset and bolt spacing i'm not sure as i don't have any maxima measurements to go off of.

turtl631

Any update on this? Me wants Cobra rotors D)

Lordrandall

Haha, nice. Jeff and I go way back.

Yes, the spacing may be a bit different because you have to shave 3mm off the radius of z32 rotors to fit z32 calipers on a Maxima. So there is a 3mm difference there between z32/240sx/J30 and the Maxima. You could technically run Jeff's brackets on a 240sx with the Cobra rotors, but you would have more pad overhang that would be optimal. Best to make custom brackets for the RWD Nissans.

So Timtiminy...any progress?

Gjohnson7

For those wondering about Maxima's and z32's. Matt sells these for the Maxima's and some run the 2004 Maxima rotors because there really close in size to the Cobra rotors.

Timtiminy, I'm having my friend contact you, he has access to some machine shop equipment and could probably get rings made up for you if you have dimensions. Clearly, I want to get these things on my car.

Lordrandall

Matt is a really nice guy, not sure how many sets he's selling these days because he moved recently. But again, a BBK designed for the Maxima will have a bit more pad overhang than is optimal. Not saying you can't use them, but there it is.

Maybe he'll make a similar kit for his 240.

Its been done for a long time, and alot of Z32 guys are rocking the 13'' stang rotors..
Guy in FL named Ash makes the brackets.

i know this is an old thread but has anyone gone forward woth this upgrade? i need just the hub ring and braket.

sil80drifter

I have the whole kit for the S13 for sale. I tested it and it worked great.
Please see my thread:

seems to me this rotor is too large for the caliper.. how this would stop any better than a z32 rotor that has a full contact patch?

z32 calipers using a z32 rotor:


I fail to see how the cobra rotor could stop the car any quicker than the z32 setup, after all you are using the same caliper and the contact patch between the rotor and the brake pad have not been increased. the use of your brackets actually decreases that patch by what did you say 1mm?

here is a STi setup with EVO rotors:


STi calipers have a larger brake pad and properly fit the EVO rotors

__________________

sil80drifter

The reason people go with the Cobra rotor is because the AREA of the rotor is larger than the 300ZX rotor. The contact patch is the same, for both rotors, the pads are completely covered by the rotor (for the Cobra upgrade this requires slight grinding of the caliper edges so that they sit closer to the rotor).

Bigger brake upgrades are very rarely about stopping faster. Stock 240SX brake are sufficient to lock up the wheels (which means all the braking power you need to stop).

Nowhere in this thread have people claimed faster stopping times. The advantage of bigger brake rotors and pads lies in their heat dissipation abilities. Being able to stop from 100-0 is no large feat. Being able to do so multiple times over without experiencing brake fade and fluid boiling is what counts. This is achieved by maximizing the area of the rotor and pad.
The EVO/STi combo is also great. The EVO rotor is not 13" though, so fade may occur faster.
