Hi to all im a new member from the land down under AUstralia
and this is a great site for information
can anyone tell me about brake up grade for my 2003 SL500
will SL55 AMG discs and calipers bolt straight on a SL500
thanks in advance for information on this topic
regards Steve

luv4eternity

im actually wondering that too!

stevohj61

I have been told you only have to drill out the front mount holes on the spindles to 14mm and they fit and the rears bolt straight on
2003 - 2005 e55 cl55 cls55 s55 AMG 8 pot front callipers will bolt on just modify disc backing covers or change them
looking for someone to confirm this before I go out and buy them
regards Steve

yes you are correct about the front. think we talked. i had to cut the dust shields also. the rears i have didn't bolt on...mounting points were different but maybe i had the wrong set. my set was off a 2005 sl55 so i will say the are correct. if you figure that part out let me know . good luck

2003-2006 Front calipers are the same, Except performance code: 030,

2003-2004 Rear calipers are the same,

2005-2008 Rear calipers will not fit, cause spindles are differs, including face lift,,

* i think Steve want to get F&R calipers from 2003 SL55..

ZAYED,,

im wondering are 2003 2004 SL55 E55 CL55 AMG pot 4 rears are the same also ?
and they may also fit SL500 rear.

what part numbers are the rear AMG 03-04 callipers

Most welcome guys,

for more clarification; there are 2 types of SL500 rear spindles & caliper bolts hole pattern, U.S version and Euro/Japan version,

prefer to measure your Exist caliper pattern holes, to avoid spending $$$$..!

75mm VS 90mm patterns,,

pls. see attached..!

i have been looking at online parts catalogs for referances to 2003 sl55 and sl500 for fitting AMG brakes
www.mbpartsexpress.com and www.genuineautoparts.com.au
part numbers for rear Knuckles are different
SL55 rear knuckle 230-350-51-08 left 230-350-52-08 right
SL500 rear knuckle 230-350-85-08 left 230-350-86-08 right
SL55 front knuckle 211-330-66-20 left 211-330-67-20 right
SL500 front knuckle 211-330-64-20 left 211-330-65-20 right

the differance must be the mounting points for the larger 8 / 4pot callipers
im trying to find out about what parts are required
dont want to buy the callipers from sl55 and the rears wont fit
ive been told you can just drill out the front knuckle calliper holes to 14mm
im just not sure on the rears
or is there a AMG rear calliper that just bolts on from a different model ?
cant seem to find info on euro/japan models

Appreciate your valued feedback, that of course reflects your Elegant sense..

Steve,

*In Front steering knuckle; The only difference between SL500 & SL55 are bolts thread,

[SL500 = M12] vs [SL55 = M14]

*In Rear knuckle/spindle; SL500 got a different spindle than SL55,

my initial conclusion that the Rear calipers which fit in your SL500 spindle should be from:-

(2006-2008 R230 SL55 facelift & SL63 or 2007 W219 CLS63),

that's why i asked if you can measure your calipers distance hole points..!

ZAYED,,

stevohj61

Good information Zayed , i will measure my bolt hole distance on my Australian 2003 SL500 rear callipers and see if i can find the part number on them as referance
i will look for part numbers for rear AMG callipers from models you have indicated
thanks again for your valuable information im sure others will be interested in this topic

AnyTime Steve,

Unfortunately; MB didn't stamped their part # in the calipers, you will just find Brembo reference #s,

just when you measure your Exist caliper hole or even spindle hole pattern, it will help more to see from which Exact AMG rear calipers you should to go with..

ZAYED,,

stevohj61

My calliper mount distance is 90mm

cm60k

If it 90mm, then you should go with:-

1) 2006-2007 W211 E63/E63S wagon

2) 2007-2008 W219 CLS63

3) 2006-2008 R230 SL55/SL63

*MB part #s:-

1) L #: "003 420 81 83"

2) R #: "003 420 82 83"

Hey Zayed,

thanks for all your helpful posts! My measurements are 90mm as well and I have calipers from a 2006 CLS55.

Do you know if the fronts would fit with just a re-drill? It looks like it would but I want to make sure before I do so. Also for the rears, it looks like rear caliper bolt holes are about 1/2" closer together compared to the rear hub. Is there anyway I can get these to fit? Thanks in advanced!

Were you able to install them? I also have a 2003 sl500 and have the chance to buy some calipers and mounting brackets from a 2006 cls55 .
