So I have a 2k5 230 SS... I got new front rotors and pads, the rotors are StopTech's (127.35057L/R). I just measured the rotors and they measure to be roughly 11.4 inches, aren't my stock rotors 13.6 inches? Can anyone tell me if got the wrong ones?

Thanks

You got the wrong ones, those are for the luxury sedans. Rotors for the 2005 C230 should be 12.9" in dia. There is a chance that even this information is wrong, MB did a lot of swapping of parts in the late 2004, early 2005 time frame.

The rears are 11.4. possible you bought those instead

These are fronts... I'm sure of that... I think that e1000 is right that I got the luxury ones. Well crap... looks like I'll be posting them in the classifieds.

In my experience, the correct front rotors for the 2005 C230K sport are hard to find aftermarket. They are not dealer only, but you may have trouble finding them anywhere else.

the oem rotors are not bad, i would stick with those. i did however bought a brembo cross drilled for the rear to match the fronts, thanks albert.

Yep, the 11.4" rotors are for the non-sport brakes. I believe your rotors should be 12.9", as e1000 stated. The CLK version of the 4-piston brakes have longer mounting arms, hence the need for the 13.6" rotors. If you want to see a side by side comparison of the 2 versions of 4-piston brakes, see this thread:
