Porsche BREMBO 4 pots for the CSL ?

[mattCSLnut]

I have a pair of these as a back up braking plan for my CSL :whistle:. Has anyone done this conversion before ? or does anyone know of someone that has ? They are the front callipers made by "BREMBO" as fitted to PORSCHE 928 S4, 944 Turbo, 968 Club Sport, 911s (1989 onwards non Turbo) and Boxter S, I think. Any advise, pointers, useful comments are more then welcomed :thumbs:

These ... I'm either going to get the Performance Friction "Z" Track Day pads (same as I have at the moment ) or something from Pagid :beer:

What sizes are the pistons in those callipers ?

************************************************** *********

The piston sizes in my BREMBO Porsche front callipers are as follows:

The two smaller ones are 36 mm in diameter
The other two, larger ones are 45 mm in diameter

I've just sent an e-mail to a German tuning/machining company with an enquiry :whistle:

Hi,

MBT will more than likely have
bracket adapters for mounting them.

From the pic posted they mount
correctly as trailing calipers.

Just make sure that when mounted
that their is no clearance issues
with the way the brake line hose
attaches to the caliper.

Some Brembos have a 45 degree lug
which the hose fits into and this can create
clearance / fitting issues.

The Gorilla.

Hi m8.
I'm no expert but just to clarify "Trailing" callipers means they mount at the back of the wheel (near the lower part of the 'A' post, as it were) and the arrow on the calliper points in the direction of forward travel , RIGHT :whistle: ? On the other hand "Leading" callipers are mounted at the front of the wheel (near/towards the front bumper, as it were) :clown:

About the brake hoses... that's my next concern which I need to resolve :smt017. Would U know the tread size & shape of the hose end, the bit that screw into the O.E. CSL callipers ? THANX for the continuing flow of info :thumbs: BTW what's the exact size of the O.E. M3 CSL front discs (350 mm in diameter X 28 mm in thickness ???)

they are old style brembos, not sure they are ok with big size disc :whistle:
absolutly not the same design as 996 onwards.

they are 345 x 28 fronts 328 x 28 rears

I have some OEM callipers in my garage if you need any pics of the fitments

They are only "Old style" on the outside.. the PORSCHE logo being of a 3 dimensional type as oppose to later smooth finish with a white PORSCHE decal. Inside they take the same pad size 131 X 71 X 18 :whistle: . They are NOT to be confused with the " BIG REDS " that U get on Porsche 928 GTS, 964 RS & TURBO + 993 TURBO which are 4 pots but bigger still. :supz:

That's very good of you to offer :thumbs: but don't go out of your way, just for lazy old me :hahaha: . Next time you're passing through the garage though, do take a few snaps :thumbs:

Hi.

MattCSLnut- Your correct on the Calipers
regarding trailing etc.

Disc size you have, and at 345mm diam your at the
top spacing for those calipers.

If the calipers take a 30mm disc you
will fine on pad thickness as well
running a 28mm thick CSL Disc.

Most Brembo are metric [ie] M10x1 Male in,
convex into the calipers,
and at the other end will be M10x1
female concave, to take the hard line
from the car.

The Gorilla.
