I have the chance to get brand spanking new c32 calipers foe a steal!
They gonna cost me about $385 each.
Is this a cheap price or what?

Queestion is:
Will it be an unproblematic swap from my original C43 calipers to C32 calipers and then bolted on my stock 334mm rotors?

Can I use the stock c43 caliper bolts or do I need to get the c32 bolts when putting on the new calipers?

Since I bought my Goodridge SS brakelines and had them installed, does c32 use the same nozzle and thread size as on the c43's brakehose connectors?

The price for these calipers is good for being a swedish sucker rip off, everything is very expensive in Sweden when it comes to AMG!
So am I going to expect any difficulties when bolting the new calipers on my stock rotors?

I am also interested by this possible change, but I think the disc on a C32 are 303mm compared to our 334mm, so much smaller. Prefer keeping the 334 or bigger than going smaller. I am perhaps wrong so will go and check around....

Some stuff here by 'Money-One' but slightly bigger stuff than the C32 : https://mbworld.org/forums/c36-amg-c...small-car.html

I now have the chance to buy C32 calipers brand new for cheap DOE!
BUT!
I like the 6 pot caliper better, big is beautiful I guess?

Which 6 pot calipers should I avoid if they are equipped with SBC electronics?
SBC was fitted first time on E-class w211 2003-2004 cars and was a direct flop?
Do you know when MB killed those calipers?

I have seen a guy on Youtube fitted calipers to his C43 from a CLK Black series car.
He also put rims from from a SL65 AMG, I guess they are 19 inch wheels?
Look at his front wheels, it looks like he used C32 calipers on his car and then switched to bigger 6 pots??????????
Here is the link:

Since I use BRABUS Monoblock V 18 inch with ET35 on front wheels, I guess that C32 calipers will fit right on without having to use any spacers?
But those 6 pot calipers do they need 19 inch wheels as a minimum for free space?

DRBC43AMG

If the standard C32 AMG has 17' rims, then 17' will also fit the C43 with C32 callipers also. You may need to go to 18' minimum for the 6 pot callipers. If I recall somewhere, the Brembo 6 pot with 355mm rotors need 18' minimum for clearance.

KJI3jflarryfe93

17 inch C32 rims uses ET37 IIRC?

17 inch C43 rims does not fit with c32 calipers!
ET is smaller IIRC ET31?
Caliper and rim will hit each other.

18 inch E55 rims don't fit with c32 calipers, need spacers.
This is what this dude had to do, fitting 3 mm spacers to his front wheels.
http://www.garaget.org/?car=128585


So the question is:
Are specific 4 pot or 6 pot calipers depended on a certain size of the rotor?
4 pots minimum to 345 mm rotor??
6 pots minimum to 360 mm rotor??

It would have been great to know if 4 or 6 pot calipers are possible to fit on standard 334mm rotors with possible minor modifications if needed?
Or is it that our 2 pot calipers are locked to our standard 334mm rotors and no other larger AMG calipers fits?

DRBC43AMG

C32 rotors are larger diameter than C43 OEM
C32 rotors are thinner than C43 OEM

See pixs below

Regarding rims, as per this fitting chart:
http://www.alloywheelsdirect.net/inf.../mercedes-benz

W202
17x7.5 ET 35 225/45R17 AMG
17x8.5 ET 30 245/40R17 AMG

W203
17x7.5 ET 35 225/45R17 AMG
17x8.5 ET 30 245/40R17 AMG
and also
17x7.5 ET 37 224/45R17 AMG
17x8.5 ET 34 245/40R17 AMG


So it seems that 17' also fit C32 with specific calipers!

It is more than offset that determines whether the wheels will work. The shape of the wheel has a lot to do with it clearing the caliper. If your wheels will work on a C32, then I would guess they'll be fine on your 43 with C32 brakes.

As far as what you'll need, its tough to say whether your stock mounting hardware will work or not, which will depend on how thick the mounting ears are on the caliper. For the brake lines, I would find a site that sells Good Ridge lines for both applications and then cross reference the part numbers. If they are the same, then you know you are good. If they aren't you might still be good but just not know until you have parts in hand.

Saaboteur

I agree. Spoke design plays a huge role in determining whether a caliper will clear without spacers or not. Wheel diameter is a factor, but not the only one to consider. My Enkei RPF1s on my S2000 are an example. 17x8 in the front, 17x9 in the rear. But the spokes are slightly convex on the front, meaning my 4-piston Stoptechs clear the 17x8s, but they won't clear the 17x9s.

I do remember reading a reference on the now defunct club202 that the 18" W210 E55 AMG Monoblocks would not clear the C32 calipers on a C43 - spacers needed - but that the 17" Monoblocks would clear.

Regarding brakelines, I think that's the least of your worries to swapping calipers. I have a feeling that the chassis side and the caliper side fittings are probably the same on C32 vs. C43, but that's just a guess. That said, if you need something different, then Goodridge, Aeroquip, Russell or any other reputable hose supplier should list a multitude of suitable adaptors to change fitting size on either the chassis or caliper side. Not to mention the ability to supply off the shelf hoses of varying lengths.

I'd try fitting the caliper, then seeing if stock brakelines work. If not, you have the caliper test fitted, and then can measure for brakeline length and buy accordingly.

DRBC43AMG

I agree, the brake lines can be adapted.
I also got confirmation from a member here who did the conversion that the C32 calipers and rotors are a straight bolt on change after reversing for trailing to leading. Recommended to get longer fixing bolts for the calipers. Don't know for 18' clearance though.

KJI3jflarryfe93

Guy you got your info from did he use the 32 rotors on a c43 with the new calipers?

where to buy longer bolts?
Hardware store?
c43 and c32 uses the same boltsize to screw the caliper in place.

Hoses are the same in size and thread, just screw it on the caliper according to the swedish dude I spoke with, guy with the c43 stationwagon I linked before.

Here is a link for a 2000 ML55 AMG calipers.
The bleeding nozzle is on a different side compared to C32 calipers? But I'm not sure here?

There are several pictures if you scroll down.

DRBC43AMG

Simple, I wrote a mail to S-500-R owner of a C43 AMG in Sweden:
https://mbworld.org/forums/members/59255-s-500-r.html
So get moving, ask him and report back please

You probably need a specialist to supply the proper bolts. Typical places like Home Despot or Cambodian Tire (I poke fun at these retailers that are prevalent in Canada) likely won't have what you need. Those caliper mounting bolts are probably 10mm or 12mm diameter, and probably of a finer thread pitch than what you could get at a 'normal' retailer. In my town, there is a lovely placed call 'Edmonton Nut and Bolt' which has been able to supply anything and everything for me when it comes to fasteners, with the exception of security torx bolts.

What I would do is acquire the calipers, test fit them, then figure out how much longer you need the fasteners. Use a thread pitch gauge to figure out the precise thread pitch, or just take them to the shop and say "I need this, but **mm longer".

KJI3jflarryfe93

yup that's the dude I emailed and he said just do it!
straight bolt on with c32 rotors!

KJI3jflarryfe93

it's easier to take the caliper to the hardware shop and try out different bolt lenghts.
if too long cut it down to be shorter.

Saaboteur

And what does our Swedish friend say about the caliper placement on the upright, ie. for sorting out the piston placement?

DRBC43AMG

Well what are you waiting for?? Just do it and keep us informed
If the Club202 forum was still active we wouldn't be asking all these questions as I'm sure the info is all in there.

KJI3jflarryfe93

I saw some pictures of an AMG ML55 2000 jeep.
This jeep has the front calipers mounted on the same place where they will sit on our c43's.
So the same calipers on a c32 are mounted in the back of the rotor.
On ML jeep caliper is mounted upper front side.
Check the close up picture with the front wheel.
http://www.blocket.se/stockholm/Merc...5.htm?ca=8&w=3

However ML jeep uses 345mm rotors up front.

I don't quite get the leading/trailing part for those C32 calipers?
If you compare the fitting position on c32 and ML55 jeep they are different.
So what kind of problems would there be with braking performance?

DRBC43AMG

No difference for calipers being front or back. Now you bring up an interesting find. Would be nice to have confirmation if the calipers on the ML55 AMG are the same as the C32. If so you have further confirmation that they can work on the C43. Also the 345mm rotor is the size used by the C32 compared to stock 334mm C43 one.

One advantage IMO for front leading calipers would be better cooling. Closer to the front air access and less piping needed to get cool air flowing towards the caliper when building or modifying cars for track and racing.

KJI3jflarryfe93

parts number for left caliper C32: 002 420 1983
Right caliper C32: 002 420 2083
Front brakepads: 0044 20 90 20

Seen on pictures calipers and pads looks to be the same in size between both vehicles c32 and ml55

DRBC43AMG

Good news! One last thing though. Do the calipers have same size pistons? If so, even more good news and would be no problem how you mount them: front or back, but just need turning around..

ECTurboGSX

Guys, it does not matter if it has staggered pistons or not. Can we please get past this? The leading piston is going to be the same whether the caliper is at 10 o'clock or 2 o'clock. You do not need to (or more specifically can NOT) flip the caliper or any of that. This shouldn't be an issue, but just check and make sure the brake line isn't getting stretched at full lock or anything like that.

Also, I would not use the stock C43 rotor with the new caliper. Buy C32 sized rotors. Tirerack had some aftermarket ones for $120 or so last time I looked. Otherwise you are going to create an edge part way down the brake pad, depending how off it is you could tweak some stuff. Not a good idea at all.

DRBC43AMG

For me it is clear that C32 calipers go with C32 rotors. Mixing c32 or C43 parts is not recommended at all, even if it is possible (which I doubt...). Could be also outright dangerous too.

jayrasheed

ok quick question, are the calipers and disks of the 32 amg same as those fitted on the 2005 203 c230 komp, c230 V6 sports pack, but bar AMG logo (mercedes logo instead?)

that would be a cheap option for me as the c36 95 disks are almost usd 500 here and are smaller than the 32 amg ones.

Saaboteur

To take weight distribution to a fastidious level, the calipers should be 'inboard', ie. within the wheel base as opposed to outside of the wheelbase. Even better, the caliper should be bottom mounted, but I don't think any major manufacturer does this, typically bottom mounting is only seen on F1 cars. And not all the time either.

But taking weight distribution to such levels on a mildly driven car probably won't make a tangible difference, and not really within the realm of the shadetree mechanic either.

KJI3jflarryfe93

ok so my idea of a design change to a newer and nicer looking caliper is not a problem.
good to know!

my idea of fitting the new caliper to my stock c43 rotor is not recommendable at all?
this would have been cheaper solution and I still have plenty of rotorlife on them.

Ok then I'll have to try and get the c32 rotors.

here is a link to an ebay auction.
these calipers looks like crap.
don't buy them!
but you can see the pistons.
