I'm going to put new rotors and brake pads on my 2008 CL550 w/ AMG sport package soon. I'm seeing conflicting information regarding the parts. Can anyone clarify, does a 2008 sport package use 335x32 mm or 350 x32 mm front rotors? And the rear 300mm or 320mm? The Mercedes parts catalog says the 350x32mm rotor is for cars without AMG sport package. AutohausAZ says I need the 350mm part. Lots of other sellers say the 335mm is the right part for my car? Who is right?

Also, are the brake pads the same for either size rotor?

Thanks in advance.

Yes, I did figure it out. I ended up just taking off a wheel, and measuring the rotor size the best I could. I could see from eyeballing it that it was 335mm in the front. I've completed the front brake pads/rotors job, and have the rears on order. BTW, I put on Pagid rotors and Bosch Quietcast brakes, and have been happy with both so far. For the rear size, I'm assuming they are 300mm, as that is paired with the 335mm. I've got those on order, and will be installing them soon.

I don't know why there is so much conflicting information out there. You wouldn't think it would be so hard to just figure out the correct part.
