Are the hubs on the front and rear full hubs or 3 tab? Trying to order spacers from Adaptec and no one seems to be sure.

 

Anyone? Tons of folks put on spacers here. Someone must have the answer.....

 

What?
Spacers mount between the rotor hat section and wheel. The hub isn't part of the stack, per se.
Looking at Adaptec's page I don't see what they are asking there either. All the spacers look like a typical spacer.
So I'm not sure what the question is.

 

If you look at the 964 PET, the pic of the hubs are different front and rear. Looks like the rears are the 3 tab type, front are full. But not sure if this applies to the turbo as the part number is different than the NA/narrow body cars

 

I don't think it matters. The spacer is in contact with the rotor hat section. Who cares what the hub looks like?
I might be missing something though.
Get a drawing from them and I will be happy to help you evaluate it.

 

Hmmm... Guess you're right. May be thinking about the hub/rotor assembly the wrong way. I'll see if I can get Adaptec to chime in here.

 

The 3 tab vs flat vs full hub. The idea of the 3 tab spacer is when spacers get in the 5/7mm range they cover the majority of the hub. the 3 tab spacer allows it to be hub and wheel centric.



As you can see that spacer would not fit on the regular full lip hub. Edward sent me a picture of the turbo rear and it looks like the front. When we had Rennline on the phone they looked at their 964 which had a full hub front but 3 tab rear, just like Porsche diagram shows. So now we are trying to find out if the rear of the turbo is different than that of a standard 964.

 

Ok, so we're talking about the hub pilot flange. It centers the rotor and the wheel to the hub.
Apparently, it's a full 360 on rear of the Turbo.

 

Yes the 964 fronts are full 360 they switched to the three tab with the 993 up front.

 

What about the rears?

 

rears are all 3 tab both 964 and 993.

 

Perfect! The answers I was looking for. Thanks Anthony.

 

Uh-uh.
The picture I posted is of my rear hub.
So, Anthony, it must be a 1991-1993, 1994 thing.
Ed, your going to have to remove a center cap on you rear wheel to confirm what you have.

 

Here are mine - 1991 3.3 964 Turbo...

FRONT:



and the REAR:

I am perplexed.

I have a friends 91 targa on my lift now and it has the three tabs. My 90, 93 and 94 all have three tabs. I don't think I have ever seen another N/A 964 with the rear 360 like yours so I am assuming it is a 91-92 964 turbo only thing. I have only had one of the 3.3's on my lift and I didn't think to check. I do know the 94's have them along with the 94 964 C4 wide body cars.

My friends 91 targa. In dire need of some seal replacement new CV boots and a other misc things.
