the rotors are built by r/b. e/c is a distributor for them. my rotors are the c32 rotors which r/b builds to 340mm specs to allow the leading edge of the caliper to contact the outside edge. happens the slk55 calipers are 340mm! so its a perfect fit.
they will also be building a matching 2 piece rotor for the rears but lead time is 8 to 10 weeks and i just bought a set of oem slk55 rotors for the rear so ill use them.


yes the dust shields are on the backside of the rotor. less than a 3" wide piece was cut off to allow the huge caliper to sit on the mounts. took less than 5 minutes to zip it off with a cutoff tool
