hey guys,
i'm just wondering if the brakes between a CLK55 are the same with CLK63.
so both are 6 piston front and 4 piston rear.

spr

Doesn't the clk55 have the same brakes as the c55? if so then they're 4 pots front.

kbk

MY05+ has 6 piston front and 4 piston rear. From just the plain appearance, it seems that 55 and 63 have identical brake kit.

The last CLK55 I drove had six-piston calipers up front and four-piston rears, but it didn't have slotted and cross drilled discs. The last CLK63 I drove definitely had slotted, cross drilled, floating rotors (in addition to the like mentioned calipers).

Mine '03 has 4 pot in the front and 2pot in the back..

but it stops good enough!!

The 03 04 CLK 55 AMGs have 4/2 piston brake setup which is identical of that of C55 AMG. 05 CLK55 AMG and 07 CLK63 AMG have 6/4 piston brake setup.
63 has slightly larger thicker rotor than 05 55 AMG rotors.
I got AMG performance brake which is like 030 brake for CLK55 AMG.
The discs are two-piece floating rotors slotted and drlled (3 holes a row)and with compound brake pads which do not produce brake dust at all. The rear discs are also slotted and drilled(this is the main difference) with compound pads for the AMG Performance Brake. The stopping power is amazing at high speed. Very stable and no judder at all even at above 155mph).
I hope this info helps.

ok well i own a 2003 C32 and i want to upgrade my brakes to the 6piston front and 4 piston rear. and i have been told that the one that will fit my car come off a CLK 55 or CLK 63 so i'm wondering if i should get them off the CLK55 or CLK63. if they are the same i guess it does not matter, but the from reading all ur info's it seems like the rotors on the 63 are better then the 55????

JLee81

Pads are the same the rotors and the calipers are different.

mertd93

Not true, 2005-2006 clk55/slk55 and 2007 clk63 all have the same setup/rotors and calipers. I have part #'s if anyone needs them.
rotors: 171 421 01 12 slk55 209 421 01 12 clk55/63
calipers: 003 420 67 83 Left 003 420 68 83 Right all cars slk55/clk55/clk63

spr

hmm. So would the 6/4 bolt right up with bigger rotors? Is there a spacer for the caliper to clear the rotors? I now amg manufactur offers that kit, but I don't know what the piston sizes are for the bias etc.

mertd93

Yes they bolt right up. And you can actually use your front C55 rotors, they are the same size 13.6, a bit heavier and a bit thinner, but they work for sure.

JLee81

nope you got them mixed up man. SLK55 and 05 CLK55 share the same part number. CLK63 has thicker rotors recheck the caliper part number as well.
I checked it when I wrote the reply. If you have the price list you will know they are different parts. I guess you are new to EPC system.

JLee81

I have done the work so I know better than the other guy showing all wrong part numbers. Some minor modification on the plate is required to fit the brake kit but nothing major.

JLee81

63 Caliper: 003 420 67 83(L)
003 420 68 83(R)
63 Rotor: 209 421 01 12

CLK/SLK 55 Caliper: 003 420 47 83(L)
003 420 48 83(R)
CLK/SLK 55 Rotor: 171 421 01 12

Just a side note. It is illegal to give out any part numbers for uses like this.
This is why I do not give out or post part numbers and also part numbers can
change without notice so people can order wrong parts based on your reply.

Please behold yourself from doing so in the future or just pm people directly.
I posted these part numbers to correct you and protect other members from
getting wrong parts.

mertd93

You have no idea what you're talking about. What is the difference between 209 421 01 12 and 171 421 01 12 , only the chassis # otherwise it's the same rotor. As for the other part #'s you put up for the clk/slk 55 calipers 003 420 47 83 and 003 420 48 83 this is for the -030 package , meaning if you want to put these calipers on a non AMG car like a clk320/500 or slk350 or C230/320. It's the same caliper just different bracket. So relax, i've done this myself also. And like i said before you can use the c32/c55 rotors or 03-04 clk55 rotors to go with the 6 piston caliper, because it's only $125 a rotor as opposed to $600.

Harry Madan

this is only the part # for the fronts, what about the back rotors and calipers?? and so this set up will fit my C32? as a bolt on item.

Harry Madan

''

So if i get the Set up of 6/4 piston from a 05' CLK 55 will fit my car? or em i better of getting them of a clk 63? (if there is no difference then i guess it would not matter right) so i can use those part # and cross check them with the dealer and see if those are right parts i'm ordering and then place an order, does anyone know of the price rage of this setup

spr

So on my point, the piston sizes are the same for the amg manufactur kit as the clk55/slk55/63 6 piston ones?

Also what modification would I have to undertake to fit them exactly? What are the costs?

What are the rear 4 piston calipers??? Are they per chance the same as the c55 fronts?? that would be sweet. What about rear rotor size and fitment issues.

I was greatly interested in this mod.

Also what are the difference between the c55 rotors and clk55/63? Sorry for my ignorance but would the thickness play a part in performance or initial bite??? Also does anyone know what pads come with the 6/4 kit from amg manufactur? are they the same as on the clk55/63?

Thanks. I am trying to see how real this would be to do and what the complete cost would be.

Neat stuff!! I greatly enjoyed modding the brakes in my 996 with stoptech 14" slotted, pagid orange, stainless lines, and srf. Although there is NO way I would go that crazy (pagid oranges) again on a street car.

JLee81

Hm.. let me tell you again.. You are wrong.
The rotors are 100 definitely different. Sorry..
The CLK55 SLK55 Rotors which is 171 421 01 12 weigh 10.158Kg.
The CLK63/CLk55 AMG Performance Rotors which is 209 421 01 12 weigh 10.603Kg.

For the calipers, they are different as well.
The CLK55 SLK55 Caliper weighes 4.840Kg(L) 4.880Kg(R).
The CLK63/CLK55 AMG Performance Caliper weighes 4.803Kg on bother sides.
How can you tell people that they are the same when the old 6 piston calipers have biased weight while the new ones don't?

All these figures are from the MB system so there you go. I think I don't need to argue about this point. They are 100% different parts though you might argue again that they are the same without any solid proof. When you look up any parts and willing to give out the information to other members, please don't look at just numbers and try to be more precise about it. The prices are also different for both of them, 63 rotors is more expensive.

What good is it to use the same rotor when you upgrade the calipers to work with better and larger discs and pads? You will only add more stress to the brake system. And brakes are something that people needs to be careful of when upgrading or modifying through this kind of DIY as it is a safety feature of a vehicle. I would like to advise anyone who is considering this mod to go to the right way instead of cutting it short using improper parts.

I am relaxed. I just don't want other members to use incorrect parts.

Take care.

JLee81

Rears are different as well. anyways I do not want to comment on this anymore. Just get the parts you like and can afford. 63/AMG Performance system is more expensive for a good reason.

spr

Hey so are the brakes different than from the slk55? I asked on there and someone stated that there are 2 different sized rotors that work with the 6 pots. thanks. I am not trying to spur any battle between you two guys but am merely trying to figure out how feasible it woudl be to do myself! Thanks Sean

JLee81

It is clear that they are different parts. Please read the thread carefully again.

spr

I was referring to the rotor size. I was told that there are 2 sizes the c55 size 13.6 or whatever and the larger 14.2. No where above were those sizes noted. I am not against you just trying to get the info to see if it's something I want to do

JLee81

C55 brake cannot accomodate 14.2 size rotor and it is not designed to do so with the small 4 pot calipers. 55 AMG Performance BBK and 63 AMG has 360mmx32mm while the the previous version has smaller not slotted rotors. I am not saying that you are against me or anything. It is that you can find these information easily online looking at Yahoo Auto, Ebay or MBUSA site which will give you more solid info.

Harry Madan

thx for all ur help guys, now here is a different side question;
are the new brembo brakes as good as the CLK63 brakes???? the brembo GT brakes????
