I have a set of early 3" 911T front struts that I need to get hubs for.. is there any chance that a set from a 911S (991 version) would work ? I found a smoking deal on 'em..

narrow body car if that matters, cookie cutter or deep six replicas being considered. TIA.

.. just realized the 991 is the 7th generation, so probably not. I have a hard time remembering which 911 model is which.

I probably have early hubs if you are in the market. As you go later, the hubs get wider.

..to add to my confusion I want vented rotors and will be using Brembo Aluminum Calipers from an Alfa (same spacing as 'M' cals from what I gather).

Then you probably want later hubs.

But didn't the original 914/6 use 32mm hubs and vented rotors?

I have 911T struts which BTW are the actual 914/6 strut part number, 40mm hubs, 914/6 rotors and I'm using Alfa calipers.
All bolt on, no funky shims etc.

The wife's 914 has the same kit except it has M calipers and cookies.

You want 40mm, but there are early and late on those as well. Early has a smaller center and takes a grease cap that goes over the center. Later is hub-centric and uses a grease cap that is pressed into the center. They both take the same bearings.

Hi Mark (great looking car!) - hey it sounds like our set ups will be the same [911T struts w/ Alfa Alum. Brembos] ..so according to your note I need to source some 40mm hubs, but before I do, I wanted to verify that your Brembos do indeed have the spacer between the two halves of the caliper?

Also, I don't suppose you'd know the p/n for the hubs you're using ?

I keep coming across hubs that are listed as "911/914-6", but they're 47mm and I'm not sure how Alfa Brembos differ from 914-6 calipers. Anyone have insight on this?

If it's on the outside of the hub I can look for you, I have the '72 teen with cookies on the lift now and I'll have the '74 fuchs car on the lift no later than next week.

Anyone know where the part number is on the hub?

I'm sure the brembo calipers have the spacer, FYI I have vented rotors on all 4 corners on the '74, the rear calipers are PMB "V calipers", this is done with 911 108mm CV hubs and stubs and 911 rear rotors cut down (4mm) with Sway-a-Way axles.

I didn't do the 5 bolt install on the '72 cookies teen, but all the parts including the struts, bilstiens, hubs, rotors, M calipers came from PMB. This car has stock redrilled rear hubs and stock /4 rear brakes, also from PMB.

Mark - I searched but couldn't quickly find the answer.. are 914/6 (specific) front rotors vented ?

Had no idea the hubs to rotor thing was gonna be a puzzle.

My bad, does the 914/6 have solid front rotors?

If so I must have 911 vented rotors and I'm 100% for sure you have to run vented rotors with the Alfa brembo's. I didn't research the parts much as I got the parts for my car from Mikes914 except for the brembos. I do know they are 911T struts but noted they were the 914/6 part number.
I have two other sets of Alfa Brembos they all have the spacer.

..and the use of the vented rotors is what's got me thinking that the 47mm hubs are necessary (w/Brembos w/spacers)... I thought the spacers could be removed (during a rebuild) for use with non-vented rotors. Maybe it's why I keep seeing 47mm hubs described as 'for 911/914-6" - 'cause it's assumed that vented rotors would be the common choice?

I think you can see the p/n on the hubs, when the wheel is removed.. down in a recess where the bolts for the rotors are. Thanks for the help guys!

All the info I have says the 914/6 had vented front rotors with 40mm hubs. Rear rotor were solid.
Brembo calipers that Mark has are similar to the 911S caliper except for the 3" mounts. The 911T & 911S calipers, 914/6 and Brembo all have 48mm pistons. But the 911S and Brembo have larger pads.

Ok, well.. what about the 911's with M-calipers.. what were their front setups, anyone? (since the Brembo is supposed to have the same offset as well as having 3" mounts.

Well I'm wrong again, the hubs on my cookies teen are 47mm.
I'm going to have to measure the front hubs on my '74 with the fuchs but eyeballing through the rim I think it's also 47mm.

Fills out the wheel well real nice on a narrow body with 205/60-15 (Fuchs) or 205/55-15 cookies) tires.
I imagine the 40's will work as well, just 7mm narrower on each side.
