So you have 300zx front brakes and your ghetto stock rears look too small ? not enough braking power in the rear? You thought about going 300zx rear brakes but have trouble getting all the parts? You want something easy and bolts on? This is it, the easiest rear brake upgrade kit for S13 & S14 !

We made an extension adapter which extends the stock caliper to use a bigger rotor, it measures 312mm or about 12.2inch.

This setup allows you to run the stock caliper and keep the existing e-brake assembly. Simple install, just bolt the caliper to the adapter, install new rotor and put everything back on and you are done!

Adapater is CNC cut from 6061 T6 aluminum for the added strength
312mm (12.2inch) Slotted Rotors
All Hardware Included

Normally, We sell these for $397.50 + S/H (which cost another $40-50)

If we can get just 3+ buyers, the price will be $390 SHIPPED

We already received 5 sets and there are 10 sets coming by next week.

If you are interested, please PM me or post to the thread.

are the rotors gold plated or something? cause damn, for a set of rotors and a couple brackets that's kinda steep isn't it?

yes similar to that yahoo auction but these rotors are slightly bigger.

hmmmmmmmmmmmmmmmmmm

last i checked, rear brakes arent *that* useful. plus, z32 f brakes w/o master cylinder doesnt have proper proportioning.

either way, its a nice option but should be packaged better, or atleast advise people to run a prop-valve in order to attain proper bias.

z32 f brakes with stock master cyl work just fine, with stock rear calipers. If you have F&R Z32, then you should do a M/C upgrade.

Stock JDM S14 & S15 comes with the same 4 piston Z32 Front calipers from the factory, and the master cylinders have the same size valving.

offtopic. (but relates to this thread and the evo/sti thread on zilvia) can you guys design/sell brackets utilizing imprezza sti/mitsubishi evolution front brembos with evolution brake rotors? how much would it be or is it better to go to our own local machine shop and get them made.

if you use the same size caliper just bigger rotors then you get no extra stopping power.........

so it's $390 to get bigger calipers with more weight but no added stopping power? am i missing something?

I was thinking the same thing,
they would need bigger calipers in the rear also to actually make a difference.

Also, would this have any negative effect/screw with the ABS system?

larger rotors equate to more braking surface area (circumference of the rotor is increased). so technically speaking, you do gain extra stopping power--regardless of whether or not the increase is significant.

not trying to justify the price, just dont want people to be misinformed.

...huh?

I think the only benefit to these things is better heat dissipation, which can hurt or help depending on your pads and how you beat on them. These are also likely to make your car stop slower due to the extra mass.

So, maybe under very particular circumstances these will help your car brake better. Under most conditions though... well, yeah, at least they look the part.

He's right, I couldn't put it into words so I Google it. Read the part for Torque and Brake Rotor.

Its true,

but for the price

you can buy a whole z32 rear setup and be a step above this setup.


300 for a full rear setup...

with this upgrade theres really no need for z32 rear calipers imo

You will obtain more rotor for heat dissipation and added brake torque. Think about a breaker bar. With a small ratched you don't have enought torque to break the bolt loose, but with a breaker bar (the end being farther away from the center point) you have more torque. Same concept here

Looks like a good upgrade for those not wanting to deal with the mess included with hooking up the Z32 e-brake. I would be in for a set, but the price is steep.

07-03-2007, 05:33 PM
I think this package deal would be more complete and reasonable with new rear brake pads included.

Nice upgrade though! may consider in the rear future forsure....

mike2016
07-11-2007, 03:23 AM
I will take that into consideration and see if there's anything we can do.

I know the price is kinda high, but unless we order like 100+ kits a time, it's not going to come down much. have to take the shipping cost into consideration too, this thing is 30+ lbs and cost a lot to ship.

feel free to post any comments & suggestions, I'll do something for you guys.

Mike,

The idea and effort is always a great "thank you" and looks good.Like everyone has stated price is what kills. maybe a set of pads, or even ss brake lines w/ quick bleeders.

I know it has to be of some frustration to present a good product and still have a want for extras included. Not to mention the fact of which you said that shipping is a lot for such an item.

Nice product none the less.

SimpleS14
07-11-2007, 08:31 AM
I'm thinking it might be good to sell just the brackets, since they are "light" and shipping will be fairly low. Since you stated the rotors are from a Mustang GT (fox body I believe)..then people can scour for rotors of their liking. This is purely a suggestion and not saying you must do this.

Good product BTW.

+4 on just the brackets. Seriously though, i could get rotors from kragen, not even with my employee discount, for like 30 bucks each, which would suit my needs just fine.

if just the brackets were sold at a decent price, ide probly pick up a set right now, even though i dont even have Z brakes or anything in my front.

GSXRJJordan
07-25-2007, 01:46 AM
yup brackets only would be the only way I could justify this setup over the actual Z32 rears.

For all wondering about Z32 fronts/stock rears, the Z31 300zx M/C works GREAT. It's biased a little to the front (either that or my Falkens are not nearly as sticky as the Feddys I have in the back), so a little more braking torque in the back would be great.

Lets get those brackets!

trsilvias13
08-07-2007, 12:02 PM
I would be in just for the brackets as well. It would be a great option and I am pretty sure you would sell it faster.

Great product, great solution. I do not want to buy z32 rear because, then I have to source everything, including proper ebrake cables, as well as BMC. Let me know if you do decide to sell just the bracket, I'll definetly buy a set.

TheWolf
08-07-2007, 09:43 PM
would you pay $200 for the brackets?? cause I think thats what he needs to keep his margin.

btw larger rotor increases stopping power due to the longer leverage it has on the wheel.

neilsan
08-08-2007, 10:05 AM
lol theyre not "big brakes" just because you put on a bigger rotor. if you use the same pads, then the contact surface is identicle. if anything you decrease stopping power by adding unsprung weight. lol...

Are you really that stupid? So are you saying if I use a 1/4" ratchet I will have the same torque as a 3' ratchet? Some people need to use their fucking brains

BAAAAHAHAHAHAHAHAHAHAHAHAH

::inhales::

AAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH


:mrmeph: since when did leverage have anything to do with friction? Go light up another rock, Paul. The extra diameter of these rotors is minimally beneficial in applied torque compared to valving and pad size of the stock rear brakes.

You should buy them though, cuz theyre definitely worth the asking price to get that big brake look

Tenchuu
08-08-2007, 06:13 PM
just a shipping thought, but there are some flat rate boxes at USPS that would ship rotors pretty good for about $9.00 each. and another ox that ships hubs/ Z calipers (pair) for the same price.

Um, seriously if you don't know something please don't act like you do. Here's a simple example for you. Do you have a bicycle? Lift up the front wheel spin it(not too fast) now try stopping it by carefully (so you don't do something stupid like put your finger in a spoke) putting your finger on the hub, it'll take awhile and you may have to press pretty hard. Now spin it at the same speed as last time and stop it with you finger on the rim and note how much less time it takes to stop. yeah it doesn't have an effect of the coeficent of friction but the applied force is being increased by the extra leverage you get from the bigger rotor. If this wasn't the case then I'm sure rotors would be much smaller in diameter.

hey i'm not saying anything about this product but god damn i'm sick of the amount of misinformation that people spew out.

I think we need another 50 posts abotu people whining that this stuff is to expensive... :loco:


I'd like to see any of you mock this all up, go to your local CNC shop, get these brackets made up, and then have it worked, for that price.

I've learned never to moan about prices of items that I can't build

Mike's a stand up guy, and I've bought quite a few things from him for my car (heck I even ordered parts when I was in Iraq, no issues!). No reason to bash this guy.



For all wondering about Z32 fronts/stock rears, the Z31 300zx M/C works GREAT. It's biased a little to the front (either that or my Falkens are not nearly as sticky as the Feddys I have in the back), so a little more braking torque in the back would be great.

Lets get those brackets!

Z31 M/C does work happy :) I love my setup!

Well put. By the time you get the 300zx setup, get new calipers, get all the parts, install all the parts, and ship all the parts, you undoubtedly would pay more, so I do believe this is an equal deal.

mind to clarify front or rear?

oh and if i remember correctly fox bodies are 4x4.25 so regardless of whether you are 4 or 5 lug you will need to get them re-drilled.

but i get wut ur sayin...not just that but the luxury to have a shop actually take ur task serously...and do it quickly and right...

Here is another question. Are the fox body rotors vented instead of the flat disc like we currently have? If that is the case it may be worth it. I am in no way trying to $hit in your thread and I think your product is a fantastic idea.
