Hello,

the vented rotors off the W108 4.5 sedans have the ventilated rotors. 280sd is correct, the calipers must be off the same version with the ventilated discs. They must be wider than your originals. Brake pad size is the same on vented and non vented versions of the W108 cars. Your spindles should work the backing plates may be different.

I am currently swithching out an entire front suspension from a 220SE sedan (rally car). I am replacing it with a ventilated disc brake suspension out of a W108 4.5. I believe it will bolt right up. A rear brake suspension will go in next. Also a bolt up item.
