Just because a part recommended frequently doesn't mean that using it makes you a "sheep," it usually means that it's built well and tested. The RacingBrake kit that I mentioned is a quality kit and was designed specifically for the FD.

Who cares if a senior member of the forum thinks one thing is better than another? You're going to go against a senior member's advice just because you don't want to be a "sheep"? Well then perhaps you should stop visiting this forum, because I thought that was kind of the point... Senior members that know how to fix and address other peoples' issues posting solutions and recommendations? Maybe I'm confused...

FYI - The RacingBrake kit I mentioned is not rare, nor is it Japanese.

If I had mentioned Endless or ProjectMu, sure, but there are plenty of other kits that were DESIGNED SPECIFICALLY for the FD that are available in the US. I've got nothing against DIY projects, but braking systems are not something you should be hoping and guessing with. Designing a braking system takes calculations and testing, not buying eBay parts and hoping everything fits.

Please explain to me the benefit of a caliper this large on your FD. Yes, it's 6-piston VS 4-pot on the stock caliper, but the stock 4-pot is more than adequate. Endless makes a 6-pot caliper that fits under the STOCK 16" wheels with larger calipers, there is absolutely no reason you need calipers from an SUV.

And you plan on trying to use these on the stock master cylinder? Hope you've got plenty of empty road in front of you...

 

i think thats just part of the reason people visit this forum...the main reason is so that rx7 lovers of the world and get together in central spot and talk and ask question and post up pictures etc. of what they love most, rx7s...

 

we know its not japanese...that guy was just making a joke...we were ragging and joking aorund about you senior members, no need to take it all serious...

 

please read the whole thread mister senior officer member forum official sir...i wrote in the beginning that i wasnt sure if i was going to need a 929 master but i would test the system first on the stock cylinder, then i was told by another guy on the forum that there was someone who already retrofitted the cayenne brakes on his FD and said he was using the stock cylinder with no issues what-so-ever and that his braking force was awesome

also in the thread you can see the picture of the inside of the caliper body, there you will see that the actual working caliper is not any larger then the cayenne turbo s caliper, its just the caliper body that porsche made flipping huge for some reason...

...and i am going to test the system against he stock system, if it stops my car significantly faster from 20, 40, and 60 to 0 then its a good BBK in my eyes

...hey look, none of us are trying to say that you senior members dont know wut ur talking about or somthing like that and ye we respect you...but we're just trying to have a good time and have FUN with our cars because essentially none of us are making a living off of our FDs and FCs, we all have them to enjoy them...its not always about whats gona put me through a corner .0000875 seconds faster than something else, i'd rather enjoy my way through that corner...

 

and last thing to Cabaynes...theres plenty of respected forum members that have retroed porsche brakes onto their cars, such as fritz flynn...y rag on my project when its been done so many times before?

 

LMFAO u want me to be really honest with you man

...i'm pretty sure this caliper weighs somewhere in the 17-19 pound range hahaha

i'm just gona reiterate this...dont buy this exact caliper!!!

i'm going to be young and stupid by using it lol....you guys want to buy the cayenne s calipers...they have alot less mass to them and weigh alot less than this too im sure

Dont get me wrong, I wasnt saying that racingbrake was not a quality kit. I think they have great kits at an affordable price, hell I will probably be purchasing the rear kit very soon. It just get old when the only things that get posted are the same thing but a different variation. I couldnt agree with you more on the senior members. They are 100% essential to the forum, but with that said just becasuse somebody does something that wasnt first endorsed by another member, doesnt mean its wrong.

 

Fritz, Damian, or Brad barber did not retro fit Porsche brakes, they purchased the kit(or acquired the kit from a car they purchased). Ultimate use to sell a kit that they fabricated from 993TT calipers and rotors by CNCing a block of aluminum to make the adapter bracket for the calipers and a different hat to line up the rotor with the caliper. Damian had some really nice true full floating rotors on his. His big reds are now on GooRoo's car. Best of luck with your project. I hope you aren't installing these just so you can say, "hey, look at how big my brakes are" even though they decrease the performance of the car. That is, by definition, rice. I guess whatever makes you happy though. I know that was your original intention when you started this thread, I'm not so sure it is now.

 

in no time you will want to go down to a 330mm rotor and a smaller caliper...

you will remember my words very soon....

but like what memphisraines82 sais..whatever makes u happy

 

i took the calipers i have and compared them to calipers from the porsche cayenne i had originally looked at and the piston size and spacing is exactly the same, the pads are the same too, so i'm guessing that the only reason why these calipers are so big is cus they are monoblock, so the mounting bracket on here is seperate from the actually caliper

this actually makes it easier for me to fit onto my car because now i can unbolt the current bracket, and CNC a new one to bolt directly on to the caliper and into the FDs caliper brackets

and no lol i'm not using these to say look how big my brakes are...when i bought these i bought them with thought that they were the same size, and the only reason i'm still gona use them even though i probably wont be able to go smaller than a 19inch rim (which i dont plan on anyway) is cus i got them for $522...it was a steal and it doesnt really make sense not to use them

dont get me wrong, the brakes are going to look awesome being that big behind the size of my wheels...but i dont really plan on constantly tracking the car either, its a spirited daily driver with a track day every few months or so

for my purposes its a bit overdone cus of the shear size of the things, but it'll work well none-the-less...and like i said, for u guys using the smaller wheels, use the calipers from the cayenne s, not the turbo s or gts, those are more then sufficient

 

lol nah these are gona stay behind my oversized wheels, for form and function purposes

i'm planning on building another FD for track use, or maybe even a miata or FC to drift with...those will have proper wheels and brakes

this car is more like a daily driver/functional show car type thing

 

I just found this on ebay. What happened?


"Hey guys...i'm selling a set of front calipers from a 2008 Porsche Cayenne Turbo S...i was going to use them to build a big brake kit for my rx7, but i totaled the car ;(...anyways the calipers are up for sale now...these things are amazing...monoblock, 6 piston, Brembo...it comes with the pads and the shims and everything...these things only have 8k miles on them, came off of a cayenne that got totaled from the rear...if you plan on doing some custom stuff like i was, you can fit a 13.5 inch - 15 inch rotor on these...i bought these for $1100 so these are definitely your gain and my loss...if you guys have any questions dont hesitate to ask, and i envy the new owners of these beasts lol"

 

Yup my mom rear ended me with our Lexus lx450, damage isn't that bad but I had to replace all the lights and the bumper :/

I'm selling them for that and cus I went to fit them on the car to check it out and it really makes sense y it was made for an SUV...they wouldn't clear my 19s only the 20s and I only use he 20s for shoots and shows

I decided to sell em off and I'm buying a set of z06 calipers and i'm gona fit up those for about 700 completely fitted up ... So this is a great thread of trail and error of DIY BBK lol

 

Don't forget to get a spare that clears your BBK . . .

G/L.

:-) neil

 

Yeah those giants seemed like they would hinder performance more then gain. All that extra unsprung weight, can't imagine how that would feel in a corner.

 

Here is my 2 cents.
http://www.racingbrake.com/Z06_Brake...t_p/z06-53.htm

 

man that ad you posted on e-bay sounds like it was written by a used car salesman??? paid $1100 when you really bought them for $500 and you were going to put them on your car but you "totaled your car" when your mom rear ended you and you have to replace your lights and bumper?

not trying to be a dick...i just think its funny

 

lol trust me i know man...but business to people i dont know is just business...the calipers retail for $1700, and i got a hell of a freaking deal on mine cus some guy didnt advertise properly

and the people on the ebay know these are worth money, the starting bid i set was $450...theres 5 days left and its already at $565, so i'm already profitting...plus i put the buy it now at $850, so i'm not really doin them that bad lol

 

you have to pull apart the calipers to get to the brake pads? i never seen that before...

 

check with your dealership again....

those calipers will clear 19inchs with no problem, if that is your concern, but i hope you realised that this bbk is not any good for the fd... you are actually doing more bad than good with this kit...

you need some engineering behind putting a kit together... you just dont pick a caliper that looks nice and just throw it on a car

 

no they will not...i know that not only because i tested them inside my 19s (has a 1mm clearance on both sides...thats just not enough) and i also know that because if u read the rest of the thread u'd see that its for the new turbo s, which runs stock 21inch rims

and there was alot of calculation and careful planning that went into my kit, not just slapping on what looks nice...it was my mistake that i bought the wrong calipers thinking they were the right ones (notice how im selling them now)...and i'm going with the z06 calipers which will also work very well with the 14inch rotors that i am installing from the g37...

please do not just say that there is no engineering involved, because believe me there is...i spent a good 2 weeks just figuring the whole system out

 

just an fyi, the z06 has a different bolt pattern than the FD, don't know if you took that into consideration or not.

 

no signs of it...

 

I think he's okay with that. The Porsche brakes was the same deal, so it shouldn't be too hard to adapt the same thing for the vette brakes.

What are you using for rear brakes?

 

can you tell us if the g37 rotors fit with any issues??
