what calipers are these?

[dondarnell]

Bought these for like $10 each garage sale. Lady said they from an old Porsche. Can anybody identify them?

[JohnJL]

Are they steel or aluminum?

[James Brown]

are they Early 911S Rear Wide L or S Caliper?

measure the on center distance between the mounting holes, they are either A or M fronts
3" M fronts
3.5" A fronts

Neither A nor M calipers have crossover lines like that.

Those are regular L calipers for solid rotors like on the back of a SWB 911 (non-S)

Or they could be earlier, like 356C calipers. I expect they will contain 35mm pistons.

Here's my wide-L for comparison:



Great find for $10 a piece!

Yeah you are probably right, the early L rear used from '65 -68 were the only steel calipers w/ the external transfer lines

I think L not wide L, it seems they do not have the spacer and the space between the pads is too narrow. Check the piston diameter and the distance between the center of the mounting holes should be 2.250 inch.

I think they are 356 rear
I am interested in buying them if you want to sell them. I have a 356
