2fromtheCouve For the sport/gts 6 piston brembo 360mm front brakes, I found the following cross references:

Mercedes: 05-06 CLK55, 07-08 CLK63, 2010 SLK55 AMG,
Lexus: 08-14 isf
Subaru: 2018 wrx sti

And there are some others as well.

neptuno239 I too spent a lot of time trying to cross reference the MB pads, then I gave up and just traced the old pad off my 09 QP5 and it matched with ones from Autozone so I gave up on the Brembos.

I'll look for them when I get home.

The brakes I use are for the 2005, which are a direct replacement for the ML55. However, many older AMG cars shared the brake options with the QP of various years, very likely all the years of QP5. It's a little of a PITA cross referencing but the pads are very high quality for the money so it's worth it to me.

One tip when buying part from MB is to walk in with a VIN that corresponds to the model year of MB your brakes fit. Otherwise, they will get all confused. For example, I knew the 2002 ML55 used the same brakes as the 2005 QP, so I walked in with a VIN I pulled off of Google and they handed the brakes to me, no questions asked. A half hour later, I was driving on my new brakes.

It is a good combination for road and track use although I don't track the car.

Fortunately, No squeezing with OEM rotors (just a couple of times when I go out from my parking garage) . Note that you loose the sensor wires.

Where did you get your pads from? What was the part number or brakes manufacture?

Thanks.

There are two contacts in the sensor that, when worn into by touching the rotor, make contact with each other to illuminate the brake warning light. If the sensor is tied back and was never worn into heavily, then it'll be fine. But if your brake warning light is already lit, then you may need to replace the sensor (hooked up or not), or somehow separate the contacts to shut the light off.

You are welcome, it is a pleasure to help keep these expensive cars maintained as affordably as possible.

ltmax Got the fronts finished today, the MKD639 pads worked perfect. They were a little tight on the ends so had to sand the sides for a few minutes to get them to slide in nice and smooth. Like the rear, the pad wear indicator didn't fit so tie wrapped that out of the way.

Overall, very satisfied with the performance of the pads and less than $120 for everything front and rear guaranteed for life and that's a big bonus since the last OEM sets only lasted 20K miles...

Made a minor mistake in my last post the rear pads DG1053 are actually semi-metallic not ceramic as I first thought.

Thanks again to those who did the research, deeply appreciated!

ltmax I know this is a pretty old thread but wanted to thank everyone who posted info here as it helped a lot finding decent (and reasonably priced) pads for my 08 QP Sport.

Since mine had the four piston rear calipers the Auto Zone DG1053 (ceramic) pads fit like a glove except they didn't have the notches in them for the break wear sensor so I just zip tied the sensor to the wiring harness and everything works great. Noticed a considerable improvement in stopping power over the worn out Brembo pads that were on it.

Had to special order the MKD639 front semi metallic pads (no ceramic option at Auto Zone) so that's a project for next weekend.

Thanks again!
