Very difficult question.

I was told that the amg manufactur kit is just a rebranded brembo GT kit. Purely hearsay of course.

Sorry to drag up an old thread, but nobody posted details on the different rotors:

171-421-01-12 is a 340 x 32mm 2-piece rotor
209-421-01-12 is a 360 x 32mm 2-piece rotor

They are not interchangeable unless you also swap calipers. The 340x32 was used on the early SLK55 through the 2007 model year (approx), from 2008-up the SLK55 got a brake downgrade to the C32K brakes (4-pot calipers, heavier 1-pc rotors). The 360mm setup is from the CLK63 and was also used on the SLK55 as part of the optional "AMG Performance Package", not to be confused with the standard SLK55 AMG brakes.

Guys, I am trying to clear something up once and for all here and I think you all can help me since you seem to have the intricate knowledge about these OEM BBKs.

I believe I have the front/rear brakes from either a 2005 CLK55 AMG or 2007-2008 CLK63 AMG, which Renntech have re-branded as their Renntech GT BBK. The reason I think that is because they look exactly like this kit another member posted: https://mbworld.org/forums/clk55-amg...ce-rotors.html

They are 360mm (14.2") 2-piece rotors and 6 piston calipers up front and 13" 4 piston rears- that much I know for sure from the purchase invoice. I also know the part numbers stamped on the calipers are 20.8885.041A & 20.8885.031A. However, the original MB brochure says that the 2005 CLK55 AMG brakes are 340mm, and that is information straight from MB that you can see here: http://www.ragtop.org/mbbrochures/20..._CLK-Class.pdf


I am also attaching pictures for reference, can someone please confirm which model my brakes came from as I want to know what all my options are when I look for rotors and pads. Renntech refuses to give me any information because they want to sell me replacement parts (with a markup). I've already paid $300 for front brake pads which I replaced prematurely in an attempt to buy pads which make less dust (and they don't), and I don't want to be forced do the same with the rotors when they need replacement.

Thanks in advance for any information you can offer! You can also PM me with information if preferred.

AMGDave

2005 CLK55 has 340x32 two-piece front rotors with 6-piston calipers.

2007-2008 CLK63 AMG has 360x32 two-piece front rotors with 6-piston calipers.

No idea what RENNtech is selling but it's very possible they are taking OE parts are rebranding them.

Nero Tenebre

They certainly are. I am fairly certain now that they are from a 2007 CLK63 AMG and were used on a 030 performance package for SLK55, CLK55 in 2005-2006 as well but that was not published in the brochure.

BUT, this information still worries me:
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.

My rotors look different from the CLK63 rotors slightly in that they don't have slots, though my rears are both slotted/drilled. My fronts are pretty worn down though, so the slots may have disappeared? I still need confirmation from an expert but I think they are the CLK63/CLK55 AMG Performance Rotors 209 421 01 12.

If all else fails.
* use a chassis number of a car to do the parts ordering if that chassis number has what you want.
* check the part number of the master cylinder
* check the validity of the ESP system.

Pre-2003 W203 C32 does not have the same ESP setup as the later models. Just be sure that your whole braking system is suitable. Don't fall in love with brake calipers and drive over the cliff like Grace Kelly.

Thank you to the people who did all the true research but I want to stress that option 030 was much more common in USA than Australia and Singapore. So we may come to a different conclusion based on local VIN.

Lets face it. You can't order 030 in Singapore or Hong Kong. By the time you hit VMax you are already in a different country. LOL.

For anyone wanting to upgrade. Study your own car first and then ask a dealer or on eBay for a VIN which matches your needs.

I was finally able to confirm that my kit is a CLK63 (not black series) part. I measured the rotor thickness as 32 mm front and 26 mm rear with a digital caliper which do not coincide with the BS parts. Also, the caliper part numbers mentioned above are likely not MB part numbers but Brembo's original part numbers.

C_DirtyTwo

Does any one know if there is a decently priced replacement rotor for the CLK63 brakes with the 2 piece 360mm rotors?

Does anyone sell just the ring, and re-use the old hat? This has to be a cheaper option than purchasing brand new 2-piece rotors, I know Racing Brake makes them for the 340mm's, but who makes them for 360mm???

Nero Tenebre

Evosport is really the only one making them but they are not ready yet.

C_DirtyTwo

and what's the price on a set for the front?

do you have to buy the whole rotor or whats the deal?

not just for the black series right?

Nero Tenebre

I don't remember, check out their website for the price. You have to buy the whole rotor and the oem hats are a different type anyways so they're not compatible. They have one for the black series and another for the regular 63, they have different offsets.

C_DirtyTwo

hmm looks like OEM is cheaper, although a little heavier than the evosport's most likely.

ChiCho55AMG

Does any one know if the W211 E55 BRAKES(the rotors,the calipers&the pads) Can Be installed on CLK55 04 ? I think they need some modifications right ? And whats the best price for used one,they are in good condition,the front and rear pads has half life..Thanks

Nero Tenebre

Most likely heavier yes. I am planning on buying the set bc the real magic happens with the rears. Reducing that rotational weight on the drive wheels will make the car noticeably faster.

C_DirtyTwo

nothing better than getting rid of some unsprung weight

Nero Tenebre

You should just look for CLK63 (non black series) brakes. There are a lot of variables to consider pulling them from another unrelated chassis.

ChiCho55AMG

Yea I Know the CLK 55 05-06 BRAKES AND CLK63 Non BS will be just plug and play,but the problem im not finding

Hey,
While I love the detail level of the information in this thread I still think that at least part of the loop needs to be closed. Of course that part of the loop has to do with my issue: I just purchased a 2002 CLK55 AMG. It still has the OEM brake system, 4 pistons in the front, 2 pistons in the rear, solid rotors all around. The purchase inspection noted that on at least two of the rotors there were signs of uneven wear and though the brakes passed both state safety and the prepurchase inspection they feel a bit squishy to me and they are on my medium term list of catch up maintenance issues from the PO. I am now looking at the brake system and when posed with a choice of repairing an old superceded or upgraded system vice investing in a newer system that bolts on and will give me superior performance, I tend to invest in the upgraded system.

Questions:
1- Will the OEM 6 piston front and 4 piston rear calipers and slotted, drilled rotors from later model (2003-2006) CLK55's fit the brackets on my 2002 CLK55, true bolt on with no need to change the offset of my cool and pristine OEM AMG rivet wheels. The thread above seems to drift a bit in discussing the ability to use brake systems from both different year CLK, and different chassied vehicles, SLK, C and E class vehicles onto a non AMG CLK. Again that assumes that I haven't twisted this up badly.

2- Will the OEM 6 piston front and 4 piston rear calipers and slotted, drilled rotors from a CLK63 AMG fit the brackets on my 2002 CLK55 AMG without the need to change my wheels because of the need for a different offset?


3- Is there such a thing as an OEM or aftermarket "AMG performance brake kit" that will bolt onto my 2002 CLK55 AMG? I Googled AMG performance brakes for 2002 ... and got stuff that did not have the level of precision that I needed to make an intelligent choice.

Any help will be appreciated, if things won't work please tell me why. If things will work and you have correct part numbers for North America I would greatly appreciate it and lastly any sense of price to do the swap would again, be greatly appreciated. Thanks.

The 6/4 CLK63 brakes will be a direct bolt on. As far as wheels go, you must have 18'' wheels, and if you list your offset I'm sure we could identify if they will still fit perfectly (which most likely they will).

Nero Tenebre

First consider budget- replacing rotors and pads is a few hundred bucks vs a few thousand to replace everything. The brakes on the 63 are much improved and even have the 2 piece front rotor. You will likely need new brackets with different calipers too. If you want to buy an aftermarket kit there are a few in the classifieds at good discounts that i would seriously consider if you have $4k to spend on it. Also if your brakes feel squishy it could be a sign there is air in the system so bleed your brakes first. If the rotors are warped its likely because the PO did not use a torque wrench to apply even pressure to the wheel bolts or your pads were not properly bedded. I'm not sure about the rotor offset difference if any but chances are that won't be a problem but you can easily examine the 63 wheel specs and I would guess they are similar. You do need at least 18" wheels to clear the 63 BBK so forget about it if you have the 17's.

City Rat

Ok, this is progress. the 6/4 combo of CLK63 will be a direct bolt on. Excellent. This now narrows the issue to wheel size. If I have 18 inch wheels I am a go. If I have 17 inch wheels no for the 6/4 CLK63 BBK. I will check tonight on the wheel size. How can I tell what the offset is? I am just learning MBZ bits so I don't know what the factory AMG rivet wheel offset is. Where could I look to find that information?

Nero Tenebre

Typically different calipers need different brackets, I would verify that or just buy one used with brackets. You can also check the part numbers for each to see if they are the same. Offset is usually on the back of the wheel indicated by ET on German cars IIRC.

ChiCho55AMG

Hey guys,would like to ask for some help, is this w209 clk 55 05 brakes or W211 E55 brakes ?

waveterrorist

no idea what from
rotors do no look like full floaters up front
