Upgraded front brakes 300 zx calipers.

[gofastgeorge]

Well, first off, weight directly relates to performance.
Both unsprung (handling), and dead weight (acceleration).
The other thing is that aluminum dissipates heat quicker.

93-98 T100 4WD Discs:

291mm diameter (11.456")
25mm thickness (0.984")

Not so sure I'd be using that caliper with a 12.75" rotor.

I'm not overlooking this, trust me. I want to get all the parts in front of me and see how it all lines up, which is easy because I work in auto parts. The contact patch for the 300ZX caliper on the 350Z track rotor is a little scary too, imo. My primary goal is to see if these calipers can be used with stock rotors and 16" wheels

What's the diameter of the stock 300ZX rotor? Is there a good online resource for this information that I have not found?

The weight difference is very little. However some more hard core individuals may think that a few extra pounds is too much. 4-5 lbs is less than the difference between different wheel and tire combos.

Yes, aluminum does dissipate heat quicker, but it's also weaker. Nissan discontinued the aluminum calipers sometime in '93 and they are becoming difficult to find. The iron calipers are still available, but they are a little on the expensive side.

300Zx rotor is 11.02" from Napaonline.com
mk4 TT is actually 12.72"

i used mk3 goodridge brake line's with my 300zx caliper's.the union bolt thread's into the caliper with no issue.i'm also using the goodridge line's on the back with my mkIV caliper's

Thanks!

Since wesbeech appears to be making things happen over there, I'm not going to worry about reproducing the nightpager brackets. I've got a few other things going on right now which are going to be getting between me and my Supra, but I'm going to keep experimenting with other brake options as I'm going to be needing an upgrade soon if I want to really enjoy my car on a track. Thanks again for your offer to let me borrow your parts. Hopefully wesbeech will get some rings made up soon so you'll be able to use them.

this is killing me- we're 22 pages in and a ton of interest and still made no progress. Am even sure that people will put in a 250 deposit and pay the difference to get this swap going. Infact i know a couple of us, satan, myself, tsuper would buy 2 sets if they had too.

Everybody knows the abs ring is the problem of doing the swap successfully ,and that shimming the hub to accomodate the mk4 rotor on an NA hub is an option.

I would like to have the rings to clear the abs ring but since am switching to a non abs brake system. The rings isnt that important to me, i'd rather help out and get others on this brake swap as well. Am just going to go with Non ABS hubs/ mk4 TT rotors and call it a day.

I'll post up Part Numbers of lines and Prices to do the Non Abs swap- in the next couple days if some of you other guys want to do the nightpager swap in the next wk or so.

There was a company that had made a bunch of these adapters, it took him a very long time to sell them.

 

[10secdream]

So is the adapter ring only for ABS or to allow the 350Z track rotors to work?

All you need is the rings, right? Take some measurements, and I'm sure somebody can get them made. If somebody can give me exact measurements for the rings, I'll get them made. I just don't have the time to produce the entire kit right now especially if wesbeech can get it done cheaper. I'm finding it difficult just to find the time to keep my car on the road.

It's to center the 350Z track rotor on our hub.

 

[ReQuieM]

Dam there is a lot of BS and slackness flying around in this thread! As mentioned more then once in here I'm sure, you need the 350z TRACK rotor which was a bembo brake package option. The standard or 'touring' disc is 11.65" or 296mm but the TRACK disc thats needed for this conversion as mentioned is 12.76" or 324mm, 30mm thick with a centre bore of 68mm.

ALL of this info is on the DBA website that I posted up earlier.

IIRC, the ring has nothing to do with ABS. It merely allows you to utilize the 350Z rotor with it' 66mm hub bore. Toyota uses a 60.1mm bore. Contact patch is diminished on the 350Z track rotor, however, it still does a fine job of stopping the car, considerably better than stock MkIII brakes. Randy Derksen (BIC) has posted up the dimensions of the centering ring before. That is the only thing I need to complete my kit I bought earlier this year.

The price is not nailed down for sure but i can do the brackets for about 200 a pair if i can sell 10 in a group buy.

If you can get a commitment from 10 buyers, how long until you can produce these and rings?

 

[wesbeech]

Ok well i got the for sure price today not as great as i hooped its 280 with rings. And if i get 10 commited ppl it will take to 8 weeks which realy sux but our shop is bussy as hell and behind. So i dono if you can get them any quicker. That is an estmate it could take less.

 

[Satan]

What's that include?

 

[tsuper92]

i don't think many people will want to invest $280 for the bracket's with the ring's

Can you shoot me a copy of your file? PM me for my email address if you're willing to hook me up with that. I'll at least talk to my dude and see what my price and wait period looks like. If I can get a copy of that file and somebody can hook me up with real numbers for the rings, I can get this done much quicker than if I use blackgamer16's parts to mock it up as we'll have to ship parts back and forth.

Thanks,
Collin

Are these the '90-'96 ones?

Also,
If we have the files (CAD?) with the dimensions, etc, couldn't this be sent out for quotes from multiple machine shops?

 

[ReQuieM]

Jump on the DBA website and check for yourself but IIRC ALL Brembo track optioned 350z's used the same calipers, pads and discs.

 

[Doward]

I just want to make sure of this.

You guys are working on a kit that puts ~13" (350z) rotors on the MKIII.

The kit uses 300zx calipers, designed for an ~11" rotor?

With pads that don't even bite the rotor completely? I'm confused....

 

[ReQuieM]

Correct. The pad has 100% disc contact but only covers 80% of the disc. The idea is that you get a better caliper (4 pot) and a larger disc (for cooling and leveraged braking).

It is by no means perfect but it is a substantial improvement over stock with out going a full BB kit.
