So after some study it looks like the REAR caliper and disk are the same on all models? NA and SRT, coupe or ragtop.

Sorry not true. Look at the part numbers in the parts manual.

 

So for the rears only, are the rotors the same size? Is it different calipers between the SRT and NA?

 

No and yes.

 

The front and rear Rotors and calipers from NA to SRT are different.

The SRT rotors and calipers are larger.

 

So I went with the STOPTECH rear rotors cross drilled and slotted on my 05 NA coupe. Put them on today they came with their street/strip pads. Got caliper rebuild kit from ROCKAUTO. Also used the NEEDSWINGS SS brake line kit so the rear is done. Plan to use the SRT fronts on this car, but still need more info on the four piston caliper and disk to use on the SRT.
So with stock 18 inch wheels on the front what is the biggest rotor that can be used on the front and what MB model do they come off of?
