Brembo Monoblock 6 piston brakes on FD for under $1000
 

Hey guys i'm starting this in a new thread...i recently picked up a set of Porsche cayenne turbo brembo brake calipers with pads for $500 bucks!!
they are 6 piston monoblock calipers that fit a 14.5 inch rotor
i am going to be custom fabricating this on my FD to see how well it works

the brake bias will be thrown i'm sure, but i think a brake proportioning valve from willwood should solve that

my plan is to use these calipers on a 14 inch G37s Stoptech slotted rotor with a custom bracket that i will CNC out of 6061 heat treated aluminum


Please bring any concerns anyone has with this project to my attention!! i want to try and knock out every kink in this project, because i think its a great way to get a big brake kit for under $1000-$1200

here are so pictures of the calipers, and one of the calipers on 14.5 inch cayenne rotor

i'll keep throwing up pictures as i source new parts and start the rebuild

They say Porsche on them... that's one problem...

Honestly, can't wait to see how this turns out. Might be a nice cost effective option. How do you think they will fit under 17 or 18's?

haha no no the caliper is going to be repainted either black or brembo silver and will most likely have either Jashaan Autosport (new start up company, that me and my partner are putting together)
or they'll say the original brembo

the main reason that i went into this build is because i'm running 20inch wheels on my car, so stopping i a bit of an issue on the stock brakes, and i did not want to go and spend 2800 bucks on some brembo 6 pistons
... and yes 20 inch wheels...and i know they are too big, but still they look flipping beautiful, take a look so you guys can see what these brakes are going on and maybe give me some suggestions on color for the brakes

Cool! Stop changing your mind and build it! Haha. Those wheels look nicer then i thought. Not sure why, but for some reason i was picturing these huge chunks of chrome that belong on an escalde. Look forward to seeing how this turns out

o no i've already bought and paid for the cayenne calipers, so those are what are going on the car
and i got a killer deal too
$575 shipped to me, brand new in the box with brand new pads too
its good to have rich friends :) lol

and believe me when my boss at ISS told me that he was going to put 20s on my FD, i basically told him to go screw himself cus hes a nut case and i nearly lost my job in defense my FD, but he put em on the car...and i bowed down to him lmao

I might have skipped it, but what are you planning on doing about the master cylinder? Surely brakes those size will need a bigger one.

i was thinking about that too, i think i'm going run with the stock master first just to see what happens
if it doesnt work well then maybe using a 929 cylinder will do the trick, what do you guys think? any other suggestions of what i could do or wut master to use???

Thats what i was going to say. The 929 master cylinder is a good cost effective upgrade for big brakes.

ok cool, what year 929 should i get it from and do you know if it bolts right in? or do i need to modify anything to make it work?

my final goal of this project is to cover all the bases so that anyone who wants to build it can do it step by step following this thread...so the more info the better!!!

The lines need modified. One from a 93 works. So whatever part number and year range that covers.

Something else I thought of, are the brake rotors going to be heavier as well? Obviously the increased size will make up for the weight in stopping ability, but what about decreased performance due to the additional unsprung weight. If you could get lighter rotors, not sure what, if any options are out there, but that would help make up for the pigs in each corner. How much do those 20" wheels weigh anyways?

Our 20inch wheels are actually pretty light, the rear on this setup is a 20x10.5 and it weighs in at just over 20 pounds.
The rear is going to get a larger rear tub tho cus I wan to push it to a 11 or 11.5 width

that's a great point tho, I will research more into the rotors and will weigh in the stock setup compared to the new setup. The new caliper should be pretty light though cus it's a forged mononlock price of aluminum

This will probably be cost effective for you, but how often are you going to find Porshe Cayenne Brembo brakes for $500? I'm just sayin, I don't really know the pricing of those breaks, but I can't want to see what happens.

this build will make it possible to do a cost effective brembo BBK for just about any porsche caliper
each persons build will just require certain build specific modifications that shouldnt be too hard to figure out on their own...
think of it more like a guideline rather than instructions

plus i surf ebay for about an hour every day or so at night, and you'd be surprised how many good deals you can find on there

I have this setup on my audi A4, but this is pretty common to the audi community

Those wheels are very light. Granted like 3-4 lbs more then stock but for 20 x 10.5 thats insanely light. A fairly generic set of 17x7 enkeis is right at 20 lbs. I read usually about 1 lb per inch wider is to be expected. But that doesnt include increased diameter. I would have expected somewhere around 30 lbs for wheels that size. Curious what size rear tire are you running and did you have any trouble fitting it?

I'd like to see a picture posted of one of those wheels on the scale :)

What brand/model wheels are those?

vistafist has already done this upgrade and I beleive he used the cayenne turbo rotors as well, he just had to make a adapting bracket. I'm also very intrested in this bbk as it is cost efective. Do you mind telling us where you sourced the cayenne turbo calipers from? Here's a link to the thread w pics

https://www.rx7club.com/suspension-wheels-tires-brakes-20/turbo-porsche-cayenne-brakes-fd-792545/

those are the ISS Forged FM-10s
its the company that i work for
we're a new 3 piece wheel company
check us out at issforged.com and www.flickr.com/issforged

see i was thinking about doing that, but then i would have to drill new holes into the rotor and i'm afraid of compromising the strength of the rotor

i found them on ebay
the guy misspelled "calipers" on the auction title so not many people came across it
he spelled it "calipes" lol

ok so heres the next update on the brake kit guys

and i need some help and thoughts

i can go with 2 paths on this...i can dish out an easy $240 on a set of stoptech slotted rotors for a g37s...they are 14inches diameter (355mm)

or

i can go for the original porsche cayenne gts rotors that are 15inches (380mm)...but those are going to be right around 400 somthin bucks...

the g37 rotors would be a direct fit onto the FD lug pattern and the cayenne rotors i'd have to open new holes in the rotor hat to fit the FD

so do you think that extra inch is worth it?
or should i just stick with 14inch?

14 inch. Save some money, weight and time.

i was thinking the same thing

but just think about those 15inch rotors behind my wheels :bigeyes:

Keep us posted ,Great Info !!! Just need A little R&D

Several people have already fabricated Porsche brakes on their cars. Albeit, they were Porsche 993 Turbo big red calipers. Fritz Flynn, Damian, and Brad Barber have done this mod. Check the archives. I think there used to be a company that made the hats for a FD too, but that was about 6-7 years ago and they might be defunct.

ok so i just ordered up the 14inch g37 rotors cus you guys were right, when im going to fit my 18s for the track they wont fit.

so last night i ordered the g37 front rotors for $240

so the total so far is about $762

i'm going to do some test right now of braking distance on the stock brakes
i'll do from 20mph-0, 40mph-0, then 60mph-0

be back later with the results

i m still gonna bet its going to be over $1000 when its all said and done

I really want to see this too. 20x10 BBS LM's weigh 26.5 lbs. If these are over 5lbs lighter and half an inch wider than the bbs' that would be amazing......Are you sure they weigh just over 20lbs?

ok i weighed in my wheels today, and its not my wheel that was just over 20 pounds :crying:
my wheels at 20x10.5 weighed in that 27 pounds rounded up...i'm pretty sad i'm not gona lie

but on the brighter note, i wasnt completely wrong about the weight that i told you guys about before...its our X-10 model wheel that weighed in at 20.89lbs at 20x9.5
so our wheels are extremely light weight and strong it just wasnt my face

but hey the nice thing is all i gota do is swap out the FM-10 face thats on my wheel now with the X-10 face, so pretty soon i will have my 20s weighing in at about 21ish pounds

sorry for the confusion guys, my bad...

have you compared price and effort with a caliper system off 350z or g35 by chance? just curious. I would imagine them simply saying porsche would jack price up a bit, also dont know about cayanne lug pattern but 350z/g35 i know is 5x114.3, what is the cayannes?

just thoughts, nothing but enthusiasm for your project! good luck!

I have a buddy that works for one of the big bbk manufacturers. I guess the G35/350Z Brembos are one of the weaker out there. I think he said the Brembos from the Evo's have a slight advantage in cooling. Probably not a huge difference but just wanted to throw that out there.

Probabbly will hold up better since an rx7 weighs so much less then a 350z

i was going to do the evo brembos on my FD first, but then i decided if i'm going to do a BBK i gota go big or go home since i'm on 20s...thats pretty much the only reason i went with the 6 piston porsches, cus they will provide a lot more stopping powering cus they need to stop a 4000 lbs truck lol

I think 14" is perfect you don't see too many front and rear bbk for the fd cause in most cases the stock brakes are sufficient for the car in many peoples eyes. The largest bbk for the fd i can think of is a 6 pistons with 355mm rotors. Really looking forward to this build.

So how much the pads run? The only reason I'm asking is because a buddy of mine owned a boxster s and when it came time to do a brake job the total price was like 2K :eek:. Hence wondering how much was the stealership taking him for.

I don't understand why you're trying to do BUDGET big brakes... the time and money you spend trying to figure all this out and having custom brackets made you could have just bought the BBK from RacingBrake and been done with it.

quoted for ignorance... good luck with your dubs and budget brakes

the 20s actually look pretty good, if not a tad too big.
I'm really looking forward to seeing this finished.

You mean he could have been a sheep and done what everybody else on this forum does....Sees what the *select* few *senior* members do and copy them?

I am very interested to see how this thing turns out!!

Sometimes the satisfaction of doing something, especially if it costs less $ is more important then the time saved by doing a cookie cutter install, or having someone else do it. I do that with pretty much every modification on my FD, I might spend all day on something and save $80, but I would much rather be working on my FD then doing my actual job to make the $80. Hell I might spend all day on something and save $10. Still worth it to some of us.

Or just spend as much money as possible on a part because it's Japanese and rare.

I always encourage budget projects. I know not everyone has $2,500 to drop on brakes, $4k to spend on a turbo kit, or $1,500 to spend on a V-Mount. There are alotta people who have a family to support but still want to tinker with the car that all of us enjoy.

I like what you are doing. I have the same plans for my rx7 when I get her back. It is possible to make this happen. See the above link. The tred jacking intened. I'm local and would love to see it and order some brackets for my personal car.

hey when you get all the components in drop them on a scale. Drop the stock ones on too for a comparison. I'm just curious.

For comparison sake the racingbrake kit for the fd (front only)

13" rotor = 16.7 lbs
caliper = 5 lbs

ok so i got the first package in today, one of the calipers...

this isnt the same cayenne caliper i test fitted from my friend's cayenne turbo s...this f%^&er is huge...theres gona be so much hating cus it is a heavy ass caliper, but i really dont care anymore just cus of the shear size of the thing, i've lost sight of weight functionality, and i'm now gona install it just to say i have the biggest possible brakes u could fit on an rx7 and i really dont care who bashes and hates on it, the fact of the matter is, its sick as hell lmfaoooooo

so this thread is still to do the build, i'm just gona say that u guys running the 18s should not buy this exact caliper
lmfao you guys are going to crack up when you see this...Oh and thats next to a stock FD rotor

Omg did that come off a school bus?

more like an 18 wheels man...its gona be a tight fit...i dont even know if its going to clear, we'll see what happens lol i'm gona pull the wheels off tomorrow and make sure they fit inside the barrels

and the brake pad surface is the size of my hand...ye...

you guys really dont understand how big these things are...but they are the size of a new born baby...
