Car is a 2008 C230 4 Matic 2.5L V6 with the sport package with option code 952.


I need to order rotors and am unsure what size the fronts are. 322mm or 295mm?


I am getting conflicting info on the rotor size with that option code so any assistance would be appreciated. I need to order rotors and am looking at Bosch Quiet cast over OEM.


I am also having a hard time finding rear cross drilled rotors like the stock ones that came on the car. I am assuming my rears are 300mm.

You don't order rotors by size---you order by the correct part number---what's your VIN!!

I am not buying OEM rotors as they rust and I want something coated like Bosch ect. Most I see on various sites are listed by size and not by Mercedes part #.


VIN is WDDGF85X18F147654

If it's a C230 they're probably 295mm

If you still have the OE drilled rotors, the rotors will have 3 holes in a row if they're 295. If they're 322, they'll have 4

Thanks Funk. I assumed they'd be the smaller ones.


I'd still like to find rear drilled but probably won't be able to unless I go OEM or some esoteric after market brand.

All you have to do is ask any rotor outlet to supply dimensions equal to F-204 421 36 12; R-204 423 15 12, else you start returning crap!!

Thanks Plutoe.


I am looking at Bosch rotors or Brembo. Not sure on pads yet. OEM brake dust is nasty.

Drilled rotors are basically for looks at this point. Also they are more prone to cracking.

To be honest it does not really matter to me if the rotors are drilled or not. That is what came stock so that is simply what I was looking for but with a coating to minimize rust. I just hate looking at a rusty rotor through the wheel spoke spaces.

My fronts are 295mm (3 holes) so would that make the rear rotors 300mm?
