C230 needs 300mm rotors
Most regular C230's are fitted with 288mm front rotors however mine needs 300mm. Despite what parts guys insist that it takes 288mm it does not. I did make the mistake of purchasing 288mm but the pads stick out the end of the rotors. I have also confirmed from Mercedes with the VIN number that it does need 300mm rotors. My local dealer does not stock them but hopes they can order a set for me.
THE questions are would the sport Package 330mm fit? Also does anyone know where I could purchase a set of 300 mm rotors?
The plot thickens - According to Mercedes parts counter the OEM Rotors are part # 203 421 05 12 described as having a 330mm diameter HOWEVER they actually measure 300mm. Has anyone measured 330mm rotors to check the actual size?

you have been given an oem part number for the rotors for your car: A2034210512.
Now if you went to google and searched, you would find this:
https://www.eeuroparts.com/Parts/561...mm-2034210512/
Which clearly states the diameter.
Also seems you can get a set of OEM rotors for $100-130.

I'm in Canada and the best price for a pair of rotors even after a discount was over $200
before taxes.
By the way I have some nice pictures of the Canadian Rockies if your interested LOL
