just our of curiousity, it seems alot of people want to do the brake conversion even though it seems like its not quite an easy swap, as in things really dont fit properly.
why are most of you looking to do the swap? for increased stopping power or just to have bigger calipers?
seems like upgrading to a street/race grade brake pad and possibly slotted rotors would do the trick to getting better stopping power?
is it mostly because the other brake kits from the other MB cars can be easily found for cheaper?

DRBC43AMG

Probably for most of the reasons you mention, but also because OE rotors are mega bucks and anything which is cheaper and had the same stopping power or greater is worth looking at

for me:
mostly for newer updated looks.
better stopping power comes as a bonus

if I had the 18 inch e55 monoblock, if would have stayed with factory brakes.
as these are not open design.
with open design rims like my Brabus V's, it will look better with newer calipers and the AMG logo.

Yes it's correct,

scale them with global "Mandiri digital weight scale".....



ZAYED,,

That’s interesting & weird,,

why would E55 ECU causes some less hp/tq....?,

as i know; C43 and the early E55 which is "98 to end of 99" sharing the same ECU,

My friend got 1999 E430 which is 275hp, when he put an ECU from E55, he reached 294hp,

and then he switch it to the C43 ECU, he got the same results...!!,

that may explains, C43/E55 uses the same ECU,,

also the retune or remapping the ECU, depends of the tuner it self,

our ME2.0 needs some qualified hand to retune it....!!

ZAYED,

100000000000+ correct upgrading to other mb callipers is very costly and I am one to believe that some good pads would do wonders for the c43 on a race circuit along with some good tires. Only thing that bemoans me most about these cars is the handling. I just dont like it at all compared to my E36 m3 and my awd mitsu. However it is a blast to drive on hwy trips and does have a descentnt level of comfort. But the motor swap still has me enjoying the car immensely.

I agree with what you say about the handling when I was at the ring with my c55 I had a lot of over steer. but the high speed stability is very good.
I also had brake fade with normal pads so want to upgrade the brakes.
back to the handling what the best thing to make it better

Dziner82

as far as shocks i would recommend to get the coilover kit or koni adjutables. i have the bilstein sports, and while they are an improvement over stock, they still allow much of the 3500lbs of the car to roll quite a bit in hard cornering.
also get really sticky tires. im finding its quite hard to get this car to handle well compared to other sports cars. but it is what it is, a mercedes sedan so can only expect so much.
that being said i still love the car.

Stiffer springs will help a lot with body roll, but come at a price.

Nice seeing the 55 in action. I just got done completely rebuilding my e55 motor, putting it in my car on Thursday, I'm excited

raw1879

good luck

Still considering the brake upgrade. ive lowered my car now and as a result the front camber is out as I went to the aliment shop they tried to adjust it but could not as it already at the end of adjustment (see pic). So Iam thinking of getting the KMAC kit for the front are they any good?

I would just upgrade the pads I purchased some EBC Redstuff pads for all around, I believe this should make a nice improvement in my braking.

DRBC43AMG

I have the Yellowstuff pads front and rear and drilled OE rotors. The Yellows are the next step up from the Reds. They are very compliant for daily use and bit hard when you aply the pedal. However, when I drive in anger on mountain roads they also fade on the long run... When I have to change pads, I will go try Pagids

ProjectC55

I bought the yellowstuff pads for the mitsu. I figured the yellowstuff pads would be good for roadracing

DRBC43AMG

The Yellowstuff pads are probably excellent for a vehicle such as the Mitsu and I know that the Porsche Driving Academy at the Silverstone race track in the UK use them on their school track cars.

The C43 has nice big rotors, but probably the biggest let down in the brake system are the callipers. A swap to four pistons would very likely improve the brakes no end without an increase in rotor size, They are a 334mm standard which is already a good dinner plate size.

Another problem is the weight of the 43... it is over 1'500kg! And lastly, 17" or 18" Monos certainly don't improve the air flow and heat removal from the brake system. Getting cool air into the brake area is essential and probably none is really getting in there at all, so anybody with an idea and a simple system to channel cool air from the front to the brakes is welcome. I know one of our friends living down under in "kangaroo" land, Ausembtech I believe, came up with something, so maybe he could chime in

raw1879

ok ive decided to do the 6 pot conversion but the calipers are back order Germany. so it will be a few weeks till I start the job. DRBC43AMG yes The brake cooling is very important and I will try to implement some cooling on my conversion

ProjectC55

Yes I need to do that on both of my cars especially the mitsu.

So are the later Clk 4 pots really an upgrade for the c43? Im gonna check Speedbenz car out since he religiously used to road race his c43 55 converted beast. He did alot of interesting things to that car. I would love to change the heavy rims on my c43 but I never really planned on road racing it. Its amazing how big the EBC racing pads are for the front brakes of the C43. When I took my car to the scale it weighed 3360lbs without me in it. I think thats kinda light. No spare and aftermarket exhaust certainly helped. Just the weight loss in the exhaust I felt in the power of the car right away.

raw1879

KMAC bushes are they any good

I changed my 2004 clk55 brakes as follows:

Bought used with 30k mile stock 4/2 setup. Spongy brakes.

Step 1 - fresh pads new rotors new fluid.......... Big improvement.

Step 2 - used rotors 6/4 rotora set up..... HUGE upgrade!!!!!! W ss brake lines

Step 3 - found a usedclk63 setup......, with 2 PC rotors ..... Having cal painted red then install.


I too was skeptical about the need for bbk on the street..... But it opens up a new dimension which I enjoy.

DRBC43AMG

but yes they are good but apparently some people have experienced some serious squeaking...

DRBC43AMG

Did you also go for the SS brake lines route at some stage? That also improves the feel

Any pics of your setup?

betrezra

Drbc... Yes with 6/4 setup.


Also, Fresh fluid, ss lines, new pads rotors is a nice upgrade on a tired stock 4/2 setup if you want simple low cost.


The 6/4 w 2 PCM rotors is sooooo aggressive........ Like a slot car on th street. Makes my portly clk55 stop like a miata.

The extra braking cap really changes what you can do with the car even in daily driving,


When you add power adders and you can hit 80-90 mph quickly I also find in fun to drag the speed down rapidly before a corner..


My baseline is from 20 yrs of Dom muscle car drum brakes and overpowered 90's mustangs with puney stock brakes.

I plan to do a track day this winter so well see.

betrezra

Raw.... I too lowered my car clk55. I bought the mb crash bolt kit which hope will allow front alignment adjust.

I bought adj heim jt control rod for the rear.

Have not done alignment since lowering on hr springs and Koni yellows.

Have not noticed any funny tire wear after a couple thousand miles.... But pretty sure ill need align.

raw1879

got the parts now for the 6 pot install just trying them out before I do the job on Saturday
