Here we go again! Zuffenhaus MS RSR project...

Brake line work has begun, new hard lines, using the old ones as templates:




Getting an idea of the bends to get the lines into the rack n pinion tunnel. This is the driver side:




Passenger Side:




Main line flared and finished:

Started working on getting the rear parking brake sorted out. From what we can tell the RSs with lug nuts used the typical brake shoe 911 rear emergency brake while the cars with center locks use the "clothes pin" style rear e brake. This build will be using the Zuffenhaus 930 style calipers that conveniently are premade to mount the clothes pin style setup. AASE currently offers a kit that is made to work with the Zuffenhaus made caliper.


AASE kit to be installed:

Is there a target date for completion? Just curious...

Will this be a static display, Pebble Beach Concours, cars & coffee, or tracked? Asking simply because of the level of details that are going into this car and the time it has taken so far to complete such details.

Hi Gus,
Great question, nothing specific with regard to a completion date, my hope is before the end of the year including the sorting that will be required to get this running well. It will be interesting to see if its possible to make the slide valves perform well on the street.

Plan is to use the car for PCA events/C&C/and 7 tenths DE driving. I live near tail of the dragon, definitely planning on some mountain weekend trips!

Pics of how it should mount from the AASE website:

Mounting bracket included with the kit:



Mounting point on the caliper for the bracket:

When we went to install the mounting bracket that came with the kit it was discovered that it wasn't wide enough for our aftermarket rotor which is 32mm thick. The kit is made for the stock 930 rotor which is 25mm or less. Ended up having to fabricate a wider bracket to fit our rotor:

[911 tweaks]

Nice…!
That’s one meaty rotor……..!!

@ktr6 Oh man! Great to see an update! Glad to hear there is momentum, as well.

Has this car been moved from North Carolina?? I see your location has changed to Knoxville.

hmm
930 used 304x32mm front and 309x28 rear rotors, only the '74-77 930 used the 911 size rotors 20mm rotors

afaik the same sizes as the '73/74 RSR



here's a very original '74 934
