I just got a free pair of JCW rotors (part 34 11 6 777 826) that were originally purchased for a relative's 2007 MCS. I have a 2006 MCSc - how does the increase in diameter of these rotors effect me, if at all? I am planning on upgrading lines and pads, but I have no intention of upgrading calipers if I don't need to. I guess the question is this - will these interchange with stock rotors with no additional upgrades needed?

Thanks, and apologies if this has been answered elsewhere.

 

You can't use those. Wrong size.

 

Thanks. I guess I should now switch this over to the marketplace, since I now have some rotors to sell
