Hi Gang,

I have some calipers that "may" work with 944 rear rotors. Working off the hunch supplies another round of problems. There's only about 4-5 different 944 rear rotors:

83-86 944
87-89 944
86 944 Turbo
87-88 944S2/Turbo
92-95 968

I can probably rule out the last 3 but the first two are tough calls... does anyone have one of these cars they can take some offset measurements off?

I need the distance from the top of the hat (where the wheel sits) to the middles of the vented rotor (or the top or the bottom, I just need to know what's being measured).

Thanks in advance.

Eric

I'll get those to ya tomorow

Danke Amigo!

Do you still want mine?

Does it fit in that first two category?

Nope. I think the category you want is the 83-86 944 or 86 951, those are early offset cars.

The one's I would be looking at have the same rotor thickness as a 70-83 911 disc.

that is 20mm thick right?

Believe so...

whatcha cooking?

did 944's have a 911 style parking brake?

I have a set of calipers that have 5mm shaved off them. The PO says the PPO may have used 944 rotors with them. I need to check because, the 5mm off makes for 10mm in the "wrong" direction.

If the 944 rotor offset is correct, it's a bolt on. (oh please, oh please, oh please)

5mm off the ears? thats a ton dude

Left is a 86 N/A, right one is an 86 Turbo.

N/A face to center of rotor = 2 3/8" turbo = 1 3/16"

N/A rotor thickness = 3/4" turbo = 1 1/16"

Does that help ya?

Oh yeah I forgot the turbo rotor in the pic is a front

yeah.. 951 front rotors are 28mm thick iirc...

and the rear has the 'flat' area for the drum e brakes too....

That does help... it indeed coincides with a caliper that's moved "out" 5mm. Now I'll measure it against a 9leben and see.

Danke Amigo!

If you wanna wait I'm going to be uncovering my car this weekend to let it run for a while, and can get a rear turbo rotor measurement for ya.

I'd bet the Turbos are thicker hence not for my application. That picture just might do the trick!

Oh, oh, oh....

How big-o-round are those???

Danke!!

Just another thing to note. I put late turbo/968 calipers on an 86 N/A and using 86 TURBO hubs and spindles still had to shave the fronts a bit ( quite possibly the 5mm you mentioned) but had to add a spacer to pull the rears in a tad.

Turbo front = 11 11/16"

N/A rear = 11 5/16"

Early 944's it is...

Took me a while but I finally dug out the car and did some cipher'n

Danke Scotty the Cat! You are a "cat" for sure.
