Ok, let me clarify, what I should have said was the 3" spacing calipers have been used on the 911 from the early models to the 89 Carrera. Early cars had both front and rear calipers with 3" spacing. Then, the front spacing on the strut was change around 1976 to the 3.5 inch. Then in 1984, the Carrera had a rear caliper with 3" spacing and bigger pistons and a wider gap. Also, the 1984-89 3.5 inch calipers had a bigger gap for the wider front rotors.

What is in questions is did the 911 'S' have 3" alum calipers on the rear. The orginal post was interested installing 3" calipers on the rear of a 914.

So if one assumes that steel M calipers refers to 3" spacing, my statement is correct


On my 914, I used the rear Carrera rotors with the rear Carrera calipers. All that was required was the spacer btwn the caliper and the mounting holes in the trailing arm. You could use earlier M calipers, but you would need to find a larger spacer btwn the two caliper halves. And nice 911 parking brake!
