View Full Version : Porsche Brakes

Hi All,

Thought I'd post some pics of what a friend and I did during the christmas holidays, the brackets that hold the calipers to the spindles are not made yet, but you get the idea.

Specs are:
360x32mm Audi RS-4 rotors with homemade steel hubs and Porsche Cayenne six piston Brembo calipers all mated to Corvette C-4 spindles.

I think it should be nice when powdecoated and painted.
Let me know what you think?

Man is that thing gonna stop!!! Wish i had some engineering backround and $$$ so i could create somthing that awsome. Keep up the good work!

Tigergutt you have a pm. Check your inbox.

Hey Andre', any reason why you didn't use the 18" rotors???? ;) looks good. I may just use the yellows and run an Audi bracket. looks great

I do not have an engineering background, I'm just a gearhead.
My friend is a mechanical engineer and have access to a machine shop.
we have about 20hours into this setup as is and there is probably ten more involved before the brackets are done, the bolts are drilled for safety wire its painted etc.
at shop rates that means 30 x $65 $1950 (in Norway they are more than double of that) plus materials

I actually thought about 380mm's (no kidding) but I found out that I had to contain myself and my wallet a bit.
If I were to redo it, I'd get some rotors that fit and buy the calipers then fabricate up the brackets.

Vince, the yellows ?? are you talking about yellow Porsche calipers? the ones from the 996, they are four pistons and Nice!
In my sick head I am alreeady thinking about using the front ones at the rear :o)

yeah,996's they aren't too bad $$. 18"/380mm sorry I forgot your over there. I was eye ballin them Cahyennes but didn't want to run 20" rims!!! I didn't think about the smaller rotors. I hope your running skid plates on your front bumpers! heha bueno

02-11-2005, 02:09 AM
Vince, 380mm is more like 15"... 18" would be close to 460mm :evil:

02-11-2005, 05:00 AM
Christer is right.
to obtain mm from inches multiply by 25,4
to obtain centimeters multiply by 2,54.
to obtain inches from mm divide by 25,4
to obtain inches from cm divide by 2,54
so its like this
360mm / 25,4 = 14,17"
380mm/ 25,4 = 14,96"
18 x 25,4 = 457,2mm

I thought about running small wheels underneath ahahaha

What do I think?!

I just had to send the link to my buddy, who isn't a PT guy, just because I thought your choices were so impressive, and also generally cool.


02-11-2005, 07:31 AM
That's pretty slick. I'm interested in seeing the final outcome. Those calipers are massive. What are going to use for a master cylinder?

02-11-2005, 08:08 AM
Glad you like it!

I thought about using the C-4 master cylinder but I'd need someone to help me calculate if that works.
Otherwise I could go with a Porsche unit.

I'll post more pics as soon as the brackets are done.


02-11-2005, 08:20 AM
sorry christer, i thought i was being sarcastic, it was a stupid comment. I will start using j/k for now on. chow j/k

02-11-2005, 08:31 AM
Vince ?? I didnt get that with sarcastic etc.
I'm sure we all understood that you was just kidding with 18" wheels

btw I just re-read my post and I meant small wheels under the bumpers instead of skid plates, I saw those on C-5 vettes, look funny.


02-11-2005, 02:03 PM
yeah I did get that in your first post but then when you put 18"/380mm in your second post I thought your math just sucked :box2:

and I'm just kidding :cheers:

02-11-2005, 07:17 PM
you tellin me, I can barely count to 5 with my shoes off, much less convert inches to mm's...wait, are you sure, I came up with 461,2...or is that 4,612...you guys suck ,he he haaa ha.

02-11-2005, 11:42 PM
Vince, it's time for your medication and to put your comfy little white jacket back on. You'll have more playtime tomorrow.

02-12-2005, 01:00 AM
Looking good looking good...

May I ask how much the rotors and calipers weight?

Keep it up! :bananna2:

02-12-2005, 01:23 AM
I dont know how much but they are for sure heavy with all that Iron.
I hope and think that they are lighter than the standard rotors with the Delco Moraine iron calipers and the steel spindles though.

I'll put it on a weight as soon as it all come down from Norway.


02-12-2005, 01:45 AM
Hey... Norway, that's close to me!!!

Ripper, Sweden :bananna2:

02-12-2005, 01:58 AM
Actually the guys are even closer right now, they are at the Ĺby swap meet.

Hey man lets do like this, you go to Oslo end weight them and then you let us all know hahahaha

The brackets are done and need to be plated, then some powdercoating on the calipers and we are good to go. :drive2:

There have been someone asking about prices of the parts, this is how I remember the prices for you car guys and girls, when my GF asks they are around half of that LOL.

Calipers on ebay euro 500 = $650
rotors on ebay euro 300 = $390
piece of steel to machine hats euro 40 = $50
I bought some bolts and nuts and hardware for around $ 100

what kills the deal would be the labour, my buddy did it for free but I made a secret agreement with his wife and paid a dinner for them but that did only piss him off nothin else.

the brackets can easily be made but doing the hats took a really long time.
If I had to do it all over I'd spend some more and buy some rotors and hats that fit, then get the calipers and only make the brackets
