R7 Throttle Pedal Extension

Need a heel/toe aid for your vintage 911? Why not follow the factory lead?   Here is our first reproduction of the throttle pedal extension used on the 1973 R7 ‘Mary Stuart’ RSR Prototype: CNC machined from 18mm marine-grade plywood for long life, this extension will help position the face of the pedal to better utilize the available factory adjustments. These extensions closely follow the pattern and dimensions of the hand-made original and will be finished in black to wear and patina with use like the real thing: Installs with provided screws into the factory pedal face for secure mounting. …

Zuffenhaus 3.6MFI

MFI for Mary.

It’s been a while since we’ve updated; as we’ve been quite busy (and thankful for that!)  since our last post. We’ve been sorting our Celette benches, adding some in-house prototyping capability, continuing physical upfit (construction) of the facility, and making some strides on the Mary Stuart RSR project. Let’s talk about Mary. She’s getting proper MFI.  (If you know anything about us, you know this makes for big smiles around here.) The engine for this project is a 3.9l based on a 3.6, and as such was not designed for use with mechanical fuel injection, although the mounting bosses for the …

Zuchs on 930 – Aggressive Fitment

You asked for it: more aggressive Zuchs fitment for wide body Porsches. The rise in popularity of the Singer Vehicle Design 911 equipped with the Zuffenhaus-Fuchs (Zuchs!) has drawn attention to the flush-fitting wheel aesthetic within the Porsche community. As a result, Zuffenhaus has been getting requests to configure the 3-piece 17inch Fuchs-styled wheels more aggressively – to really fill out the body work and get as much ‘dish’ (deep outer lip) as possible. Here’s the result: Front 3/4 view Rear 3/4 And a side view to show off the RSR Finish. 😉 Let us know when you are ready …

964 Backdate RSR

Just a quickie for Friday. This is the long overdue 964-to-1972 RSR build, on the rack for suspension rough-in. It’s the business, most assuredly. Initial rough-in is for ride height and rake decision-making, as well as creating a square and level base for hanging the front bodywork. Normally we’d set up a 964 nearly flat at the sills, but it just won’t say ‘911’ without some rake. This RSR is sans interior, trunk lid, fenders, fuel tank, and bumpers, but is respectably light even at this stage: Not bad for all-steel with sound-deadening. Completed project will have stereo, AC, and …

1974 RSR Endurance Calipers!

Ever seen any 1974 RSR endurance calipers? In person? We’ve finished up a cosmetic resurfacing and crossover line replacement on these historic pieces, and I thought you guys would appreciate some pictures before they are put back into service. Here they are on the Zuffenhaus conference table, prior to packing: :thumbs up:
